Composite Pressure &
Temperature Relief Valves
Composite bodied valves have many benefits including
a reduction in both weight and heat loss, our Composite
Pressure & Temperature Relief Valve has the added benefit
of being fully rotatable after installation allowing for the ideal
positioning of the outlet pipe. It features a brass adapter
which can be fitted directly to a water heater using circlips
rather than threads and features a stainless steel seat to
prevent seat erosion damage and increase the valves lifespan.

15mm Compact Inlet Control Valve
Unvented systems of 15 - 100 litres are most often fitted
with a 15mm supply pipe, yet the industry standard 22mm
Inlet Controls have meant it is necessary to use either
separate components or oversized controls. The Reliance
Water Controls 15mm Inlet Control Valve gives you all of
the advantages of a combination valve; reduced size,
quicker installation, fewer joints and easier maintenance
and servicing whilst being
one of the only Inlet Controls
designed specifically for
smaller systems.
See page 17.
See page 22.
Heatguard Compact
The Heatguard Compact Pre-set tempering valve is a space
and energy saving solution for use on an unvented cylinder.
A tempering valve generally functions very similar to a
thermostatic mixing valve, the main differences being in the
flow rates, which are typically higher as the valve is feeding
a complete system, not just the point of use like a shower
or bath. By using a tempering valve it is possible to actually
reduce the amount of stored hot water that is needed for an
installation. For instance if 100 litres of hot water is stored at
70°C and a tempering valve is used to then blend this hot
water with cold, down to 55°C, the actual useable hot water
that is available is over 150 litres. This means that you can
still provide the same amount of useable hot water whilst
allowing the cylinder size and footprint to be greatly reduced.
The other advantage is that
because the tempering valve
is thermostatic the 55°C set
temperature stays stable until
the temperature drops off
below 56° - 57°C.
See page 50.

Flat Spring Loaded
Expansion Vessels
One of the biggest reasons for boiler breakdowns in the UK is
from systems that slowly lose pressure over time because of
a loss of air pressure in the expansion vessel. In today’s world
of modern boilers, almost all new systems are filled from the
mains and then sealed off, this means that if water is lost from
the pressure relief valve because of the vessel air pressure
being depleted then there is no way for it to automatically
refill. Below 0.5 bar the boiler will typically shut down and
a plumber needs to be called, service costs can add up to
hundreds of pounds depending on how hard it is to re-charge
the air pressure in the vessel. The spring loaded vessel avoids
this by having no air cushion to lose. Instead the expansion
is controlled by means of a calibrated spring which never
loses its ability to compensate for pressure changes, it never
loses its pre-charge, because it does not have one, and it will
continue to work, maintenance free, for the life of the boiler.
See page 30.
Pressure & Temperature Combi Valve
The Pressure & Temperature Combi Valve is a unique,
patented valve that combines the Pressure and Temperature
Relief Valve, Expansion Relief Valve and Check Valve into
one body, making a compact and easy to install solution
which eliminates the need for an additional expansion
relief valve.
See page 24.
28mm High Flow One Piece
Inlet Control Valve
The new 28mm One Piece Inlet Control is the next step in
the evolution of our mains water control groups for larger
cylinders. Aiming to provide a smaller, lighter product with the
same high performance, the valve includes a balanced take
off port, an expansion vessel connection port, a one-piece
Pressure Reducing Valve cartridge, that can be supplied
pre-set or adjustable, and a composite bodied relief valve.
See page 16.
Dry Trap Tundish
The latest edition of Part G of the Building Regulations makes
specific allowance for discharging the drain pipe from an
unvented systems relief valves directly into a soil stack. Prior
to 2010 the drain pipe had to be routed to a point at low level
outside the building and discharge into a covered grate.
The main considerations that Part G stipulates is that the
pipes conveying the waste water to the drainage system and
the soil pipe should be suitable for the temperature of the
water being discharged into it. It is typical practice to fit both
a trap, to prevent smells coming up through the drainage
system, and a tundish to prevent any chance of backflow
into the potable water system. The dry trap tundish achieves
both of these functions in one compact, easy to fit product.

As a key supplier and pioneer in the design and development
of controls for unvented hot water systems, RWC UK has
by far the largest and most innovative range of products
on the market. Their unique features and benefits ensure
superior performance, ease of installation, and trouble
free maintenance.
All unvented systems require certain key components:
Inlet Controls: combining the technology of a pressure reducing valve,
single check valve and expansion relief valve in one single valve, these are
required to control the mains pressure, protect the main water supply from
contamination and to protect the unvented cylinder from over pressurisation.
Expansion vessels: these allow for the expansion of water when the
system is heated.
Tundish: provides type AA backflow prevention to protect the main water
from discharge which may occur either from the pressure and temperature
relief valve or the expansion relief valve within the inlet control.
Additionally on indirect systems:
Zone Valve: this is used as a safety control and is linked to a thermostat to isolate the heat
input to the coil of an indirect system, to ensure the cylinder doesn’t overheat.
Dual Thermostat: a combination control thermostat and non-self-resetting high limit thermostat.
These controls represent the first and second line of defence to prevent overheating, with the
Pressure & Temperature Relief Valve being the third and final one.
RWC UK manufacture, source and package these components to offer a complete solution in the
form of our G3 Unvented Kits. Over the years the kits have become highly customised to include
not only the standard legally required parts but also specific components and accessories for
individual customers, and today we boast over 300 different kits.
A Kanban service is also available for individual components. Ideal for pre-plumbed assembly
lines, this allows a minimum stockholding by the customer which RWC UK can replenish on a daily
basis or as required.

Inlet CONTROL
VALVES
10
The key factor that has always been at the forefront
of our thinking when developing inlet controls can
be summed up in one word... Quality.
Reliance Worldwide Corporation has a long history of providing
high quality, innovative control valves to the unvented hot water
industry. As one of the first manufacturers to supply an Inlet Controls
package featuring a pressure reducing valve, expansion relief valve
and single check valve, we have grown and developed with the
industry resulting in today’s single body, multi-function valves.
Quality in design
Our range of inlet controls have been developed to address issues such as size, weight,
ease of installation and cost. Many of the designs are centred around a one-piece
cartridge principle meaning only two cartridges are required to completely refurbish
the valve. Although the range is the biggest and most varied in the industry, we pride
ourselves on flexibility and can customise controls to suit individual requirements.
Quality in manufacture
Our valves are manufactured in facilities of the highest integrity and
subject to thorough testing regimes and exacting quality control systems.
Quality in innovation
RWC UK have launched many industry firsts over the years, including the first 22mm
& 28mm One Piece Inlet Control and the first inlet control with a balanced take-off and
expansion vessel connection, our innovations are now the standard throughout the
unvented hot water industry.

Pressure & Temperature
Relief Valves
20
Reliance Worldwide Corporation is the world’s biggest
manufacturer of Pressure and Temperature Relief Valves
with some 9 million valves produced each year at our
factories in Australia and the USA.
When the water regulators began discussing the fitting of unvented
systems in the UK, some 30 years ago, the first prescribed element
was the Pressure and Temperature Relief Valve (P&T). They believed
that the most critical safety issue in an unvented system is the risk
of overheating, which makes the P&T the most important control
valve on a hot water cylinder. It is the last line of defence to prevent
a cylinder from overheating and safeguard against the damage this
could cause.
Our range of products is vast, with sizes between ½" and 2",
a choice of probe lengths, a variety of inlet and outlet connections
and custom pressure settings. RWC UK has a Pressure and
Temperature Relief Valve for every requirement.

Expansion
Vessels
26
As a crucial component in an unvented system,
expansion vessels are a key part of the
Reliance Water Controls range.
The function of the expansion vessel is to help maintain stable
system pressure by absorbing the increase in pressure when the
water temperature increases.
RWC UK is a leading supplier of Aquasystems branded expansion
vessels to the unvented systems market. These high quality,
epoxy coated steel vessels are designed with a stainless steel
flange on potable water vessels and a galvanised steel flange
on heating vessels, as well as a special diffuser plate to prevent
high velocity noise. All Aquasystems vessels also have a special
high density, removable membrane making them easy to replace
and are guaranteed for 2 years against loss of air pressure.
Our range is the most comprehensive in the industry offering everything from 0.16 litre
shock arrestors up to 5000 litre vessels with vessels for potable water, heating systems,
solar systems, and numerous bespoke solutions, including customised pressure
settings, packaging and labelling, for individual requirements.
Our potable water vessels with integral bracket were another industry first, replacing
difficult to install straps with a secure, wall mounted fixing point.

Expansion Vessels
Flat Spring Loaded Expansion Vessels
A range of unique and innovative spring loaded vessels designed for use in
heating systems. The vessels patented design utilises an internal spring to
compensate for system pressure changes instead of the traditional air cushion
which means the vessel will never need re-charging during its lifespan.
• The vessel uses a spring, not air, to absorb pressure so it never needs re-charging
• Hot dipped galvanised finish gives superior corrosion resistance over epoxy coated heating vessels
• Unique membrane design prevents air locks and ensures even water distribution on commissioning
• The patented spring design and added capacity allows for smaller vessels to be used than
with an air charged vessel

PRESSURE REDUCING
VALVES
36
Constant research, development and innovation has
maintained RWC UK’s position as market leading
supplier of Pressure Reducing Valves for 25 years,
with over 7 million valves installed in the UK alone.
The water systems in domestic, commercial and industrial
properties can present unique problems and challenges
as plumbing fittings become ever more sophisticated.
The water supply pressure in the UK can vary from 1.0 bar to 20.0 bar (or even higher
in some low usage areas). The water pressure will also tend to vary through the day,
for instance at high usage times (typically mornings and late afternoons) the pressure
may drop by comparison with low water usage times (throughout the night, for example),
when the pressure may increase dramatically.
Such periods of high pressure can cause several problems: excessive noise from high
flow velocities, water hammer from quick closing taps or solenoid valves, plus the risk
of water wastage is particularly great because higher pressure means higher flow rates.
The water supply usually enters domestic dwellings beneath the kitchen sink so the first
effect of high pressure is often experienced at that point; when the cold tap is turned on
too quickly or too far, this creates a gush of water which hits the bottom of the sink and
bounces back, soaking the user and creating a wet mess! The best way to control high
pressure is by installing a pressure reducing valve. These take a high pressure at the
inlet, then the valve reduces it to a lower pressure at the outlet as desired, under both
flow and no-flow conditions. All Reliance pressure reducing valves are WRAS approved:
this means that they have undergone independent third party testing to ensure that
they comply with the current UK water regulations for pressure reducing valves. It also
ensures that all materials used within the make-up of the valves have been verified as
safe for potable water systems.

Pressure
RELIEF Valves
42
Pressure Relief Valves play an important role in the
unvented system by helping to control the pressures
within the cylinder and the wider plumbing system.
The valve will open and allow a small amount of water to discharge when
the increased pressure generated during hot cycles exceeds a certain
point to prevent damage to the water heater or other system components.
This means that the pressure relief valve becomes a “passive” safety valve which only ever
opens if the expansion vessel fails or if there is some other sudden surge in pressure.
RWC UK market a vast range of pressure relief valves for both potable water and heating
systems in sizes from DN15 to DN50, some with stainless steel seats and in many different
standard pressures. Custom settings are also available on request.

Thermostatics
48
One of the key competencies of the Reliance Worldwide
Group is the design, manufacture and distribution
of advanced Thermostatic Mixing Valves (TMV)
for both point of use and whole system control.
As a global leader in the field, we offer a vast range
of products to suit many different applications.
Large commercial systems can benefit from Thermostatic Mixing
Valves for both economic and hygiene reasons; fitting a TMV allows
much higher temperatures in calorifiers which can help keep
systems free of bacteria such as legionella.
In domestic systems, G3 Building Regulations in the UK require the fitting of a TMV
where the water heater is fed by a potentially uncontrolled heat source such as solar
or biomass. The valve controls the temperature of the hot water being fed to the system
whilst also providing economic advantages such as reducing the size of the cylinder
required to generate the necessary amount of hot water.

BACKFLOW
PREVENTION
54
The Reliance Water Controls Backflow Prevention
range includes single and double check valves,
as well as specialist products such as Tundishes
and RPZ (Reduced Pressure Zone) Valves to further
safeguard and protect the system and its users.
Backflow means flow in a direction contrary to the intended normal
direction of flow, within or from a water fitting. In the UK, potable water
is categorized into fluid categories:
Fluid Category 1 is wholesome water supplied by the water undertaker)
i.e. water supplied directly from the water undertaker’s main.
Fluid Category 2 is water in Fluid Category 1 whose aesthetic quality
is impaired as a result of a change in its temperature, or the presence
of substances or organisms causing a change in its taste, odour or
appearance, including water in a hot water distribution system.
To guard against contamination caused by backflow of fluid in the water heater entering into
the fluid in the incoming mains, UK water regulations require that a minimum of a single check
valve be fitted to the cold water inlet of an unvented water heater.

BACKFLOW PREVENTION
Backflow Prevention
What is Backflow?
Backflow is a term which is used to describe water which is flowing in a direction contrary to the intended ‘normal’ direction of
flow within or from a water fitting. This may be caused by either back siphon-age; a system condition where there is a sudden
interruption of a supply to a property, thus creating a vacuum in the pipework or backpressure; where the incoming pressure
from the supply is less than the pressure within the plumbing system.
As protection of drinking water is vital to public health, water regulations stipulate that backflow prevention devices should
be fitted to plumbing system to ensure that, even if backpressure or back siphon-age occur, the water supply will not be
contaminated as a result.
Fluid categories and risks, as scheduled in the water supply (water fittings) regulation 1999
Fluid Category 1: Wholesome water supplied by the water
undertaker and complying with the requirements of regulations
made under section 67 of the Water Industry Act 1991
Fluid Category 4: Fluid which represents a significant
health hazard due to the concentration of toxic substances,
including any fluid which contains:
(a) i.e. water supplied directly from the undertaker’s main.
(a)Chemical, carcinogenic substances or pesticides
(including insecticides and herbicides); or
Fluid Category 2: Water in fluid category 1 whose aesthetic
quality is impaired as a result of:
(a) A change in temperature, or
(b)The presence of substances or organisms causing
a change in its taste, odour or appearance,
including water in a hot water distribution system.
Fluid Category 3: Fluid which represents a slight health
hazard because of the concentration of substances of
low toxicity, including any fluid which contains:
(b)Environmental organisms of potential health significance
Fluid Category 5: Fluid which represents a serious
health hazard because of the concentration of pathogenic
organisms, radioactive or very toxic substances,
including any fluid which contains:
(a) Faecal material or other human waste; or
(b) Butchery or other animal waste; or
(c) Pathogens from any source
(a)Ethylene glycol, copper sulphate solution,
or similar chemical activities; or
(b) Sodium hypochlorite (chloros and common disinfectants)

Thermostats

Control and safety are vital elements
of unvented system design.
In terms of control, it is important for system designers and installers
to ensure that the systems which they supply are compliant with both
the requirements of building regulation part G3, which relates to hot
water, and the applicable parts of Part L, relating to conservation of
fuel and power. The Reliance Water Controls range of thermostats,
programmers and programmable room stats help system designers
and installers maximise the control and efficiency of hot water and
heating systems.
In terms of safety, the control thermostat is the first line of defence
in regulating the temperature within a hot water heater. If the control
thermostat fails then the next line of defence is a secondary high limit
thermostat. When activated, this thermostat will cut off any heat input to
the water heater, and must be manually reset so that the installer/end
user is aware that a problem has occurred. Reliance Water Controls
market a large range of these products including individual control and
high limit thermostats as well as a dual thermostat which combines
both functions in one compact solution.

The brand
behind the
products.
At Reliance we may have led the UK in
water control systems since 1986. We
may have over 700 patents, industrial
designs and trademarks across the
world. But to really earn the trust of our
customers, we have also created five
core pillars, which support our brand.
“We offer comprehensive
warranties, but in truth,
they’re very rarely needed.”
72
INNOVATION
We set the benchmark for water controls through customer-led insights
that help us to invent and enhance products that are perfectly suited to
the modern built environment, today and tomorrow.
QUALITY
Our products are robust and hardwearing, made to the highest
specifications, using pioneering techniques and only the very best
materials. We meet or exceed all relevant UK product standards,

73
PRODUCT
CATEGORIES.
To help our customers, we’ve developed
six product categories which encompass
our complete range. These product groups
cover everything - from flow and temperature,
to heating, washrooms and plumbing.
So whether you’re a specifier, installer,
merchant or distributor, you’ll find everything
that you need.

At Reliance, we have created a broad range of
products to help control the temperature, flow and
safety of water distribution, heating and cooling
for both commercial and domestic buildings.
We pride ourselves on gaining insights from our
customers to help shape our future products.
Whatever the sector, and whatever the commercial
and legislative requirements, we can provide the
perfect system solution for modern buildings.
Public health is always paramount - we’ll meet the
regulations so you can ensure water safety at all
times. But this is also about efficiency as much
as reassurance. Installing the right products for

RESIDENTIAL NEW BUILD
COMMERCIAL
Many of our temperature and flow products, and our
plumbing and heating systems, are deployed across all
types of commercial buildings, silently doing their job to
provide safety, efficiency and to meet the highest legislation,
standards and best practice.
Our washroom solutions are equally at home in commercial
applications. Commercial washrooms often come with diverse
requirements, which is where our range come into its own.
Diverse enough to meet the challenges of projects large and
small, across hospitality, retail or office. Our systems help
provide safe, durable and hygienic facilities, as well as assisting
reduced water consumption to conform to the recommendations
set by BREEAM. Solutions such as time flow and infra-red
controlled taps for enhanced efficiency, reduced risk of flooding
and increased hygiene control.
Designing and maintaining a safe and highly efficient plumbing
and heating system or high-quality commercial washroom has
never been easier.
EDUCATION
There are no shortcuts to providing heating and water for
schools, colleges and universities. With the welfare of children
at stake, safety is of the utmost importance.
Our systems are specifically designed for these environments –
operating at higher temperatures to prevent the growth
of bacteria, but always balanced with anti-scald features.
You’ll also find anti-Legionella valves to maintain circulation
and prevent stagnation, or Thermostatic Mixing Valves that
are approved to a minimum of TMV2 standard.
Other solutions include time flow taps to aid water efficiency
and ultra-hygienic infra-red controls with hands-free and
automatic flushing.
When designing for the education sector we can supply
a system with genuine intelligence.
77
Health Care - care homes
All hospitals and care homes should operate to the highest
hygiene standards. Reliance helps make this possible with
a broad range of heating and water systems, which are
specifically designed to ensure resident safety and wellbeing.
Of course our range includes anti-scald and anti-bacteria
systems, and with Reliance compliance is at the top of our
agenda so you can select TMV3-compliant products for the
highest levels of prevention and protection.
Providing care is also about providing comfort. Our range
of room thermostats and heating programmers provide
precise temperature control to ensure optimal heating
system performance whilst making sure a Care Home
still feels like home.
Health Care - Hospitals
In addition to providing solutions to meet or exceed all current
safety and hygiene standards, our healthcare washroom systems
feature a number of innovations designed to boost efficiency
and provide cost-savings opportunities.
One such innovation is our single cartridge which will fit all our
taps, showers and shower panel systems. This simple initiative
helps reduce inventory costs and avoid the risk of waste and
damage associated with fitting the wrong cartridge.
We have also developed a concealed shower unit system with a
unique two-step installation to help avoid damage and parts loss
during the project construction and fit out phases. Our specially
designed thermostatic taps and showers, with long levers
and easy-to-use controls, are easy to maintain and repair essential in reducing downtime.
78
Hospitality
Reliance systems can be found in a wide range of hospitality
focused buildings, helping the building operators provide a
safe environment in a highly efficient and cost effective manner.
For venues and large public areas, we have a range of plumbing,
heating and water safety systems to help create a safe and
welcoming building ambience. We offer a comprehensive
selection of washroom solutions too, such as timed-flow and
mixer taps which utilise high performance and control to provide
the best user experience.
As safe water isn’t just about temperature, the Reliance range
of reduced pressure zone valves prevents contaminated water
entering into the wholesome water further safeguarding both
the water system and it’s users.
RESIDENTIAL - NEW BUILD & REPAIR,
MAINTENANCE & IMPROVEMENT
New build developments demand efficient plumbing and
heating systems that are both cost effective to purchase and
install and meet all necessary legislation and standards.
At Reliance, we excel in this area. With a broad range of
solutions that optimise performance and cost efficiency,
the SharkBite push-fit range is the connection in the system.
Rapid jointing, high performance and total flexibility.
Our hot water systems for domestic environments take into
account all building specifications and the safety of occupants.
The Reliance range of TMVs includes solutions for both new
build and retro-fit projects, all with the same leading standard
in thermostatic technology and reliability.
You can trust Reliance to find the right solution for you.
79
RESIDENTIAL - MULTI-OCCUPANCY
Multi-occupancy buildings such as apartment blocks,
student accommodation and hotels present building designers
and specifiers with multiple challenges. With our experience
of developing unique solutions for this type of building,
we can supply standard products and bespoke systems
which offer effective space heating and safe hot water delivery.
Our Radiance Thermal Interface Units, for example, can
provide each apartment with individual control of heating

REtail
The building demands of the retail sector are quite varied.
So when it comes to selecting plumbing and heating systems,
or fitting out staff or public washrooms, you need an
experienced partner with the expertise and breadth of
range to offer flexible solutions.
Reliance is well equipped to be that partner. Our product
solutions are both high performance and cost effective,
combining efficiency factors with safety, hygiene and control.
SECURE FACILITIES
Secure facilities such as prisons and detention centres
have very specialist requirements and unique challenges.
Our water systems for secure environments go far above
the usual performance, safe water distribution and
durability standards.
Features such as anti-ligature and vandal-resistant shower
heads and basin spouts are designed to prevent the
opportunity for self-harm and misuse. And with water
management becoming an increasing priority, our range
has been developed to help architects and specifiers design
with confidence. Whatever the criteria, you can be safe
in the knowledge our systems will stand up to the test.
SPORTS & LEISURE
Sports & leisure is all about performance. Not just with the
activities which take place, but also in the facilities.
Specific requirements might include the need to install a water
system capable of balancing high-quality showering with water
efficiency and, of course, hygiene and safety. The complex
demands of this sector require intuitive design combined with
eye-catching aesthetics. Customers demand it. Fortunately, at
Reliance we’ve exactly the right products for the job. Our diverse
range of group mixing valves is ideal for guaranteeing both flow
rates and safe temperatures from a bank of showers. We also
stock a range of time flow and infra-red controlled taps, which
are often a must. All economical. All still delivering on looks.
