Sanitary Fittings Inside Toilet Likely To
Contribute Smell
Water Closet (WC)
2. Urinal Bowl
3. Floor Trap
4. Wash Basin
NOTES:
 Wet “dirty” looking floor stain with shoes marks, etc
DOES NOT contribute to smelly toilet rather it is
unsightly and is a SAFETY concern of the users.
 Fitting’s water seal prevents foul smell from the
sanitary system entering the building. Vent pipe
protects the water seal and helps maintain a STABLE
discharge stack.

TRAP as described in BS5572
6.2 Traps
Traps should be designed so that deposits
do not accumulate. A trap which is not an
integral part of an appliances should be
attached to, and be immediately beneath, its
outlet and be self-cleansing. The internal
surface of the trap should be smooth
throughout. All traps should be accessible
and provided with an adequate facility for
cleansing. There can be advantages in
providing traps which are capable of being
readily removed or dismantle.

Floor Trap
Identify the sources of smell from the Floor Trap:
3.1 Accumulated organic materials/debris inside the
water seal decaying emitting foul smell
3.2 Difficult or inaccessible areas within the Floor Trap
ABOVE the water seal
3.3 Loss of Floor Trap water seal only to P-trap or S-trap
3.4 No water seal on the floor trap especially on the
Ground Floor
3.5 Water seal dried up allowing foul smell to enter the
building

CORNER, WATER
SEAL DRIES UP
Use Spind 6,
discharge the basin
water into the floor
trap, hence water seal
will not dry up.

How Does A Floor Trap Works?
Spind 2 and Spind 6
How Does A Floor Trap Works?
1.0 Basin discharge BY PASS the water seal and goes directly to the
stack. An advantage to discharge BELOW water seal!
2.0 Ceiling height reduction 150mm verse 275 mm. Spind 6 preferred
How Does A Floor Trap Works?
VENT PIPE PROVISION
1.0 Basin discharge on TOP of water seal entering from the side. An
advantage to top up the water seal REGULARLY
2.0 Ceiling height reduction 275mm verse 400mm. Spind 6 preferred
SPIND 6 TYPES
 SPIND I
 SPIND II
 SPIND IV
 SPIND 6
 SPIND Mini
 SPIND SF
 Do you wish to MINIMIZE floor trap/gully piping
below the floor slab, hence SPACE SAVING on the
floor below
 Achieve 0(zero)mm space for piping below – SPIND SF,
condition – floor is wet often to refill the water seal!
SPIND SIDE FLOW
Water Seepage Concern?

floor gully/trap is embedded in the floor
slab. Ribbed outer casing allows for water proof joint
with concrete there is no chance of water seeping
below.
Top Access Floor Trap WITHOUT

WITHOUT water seal Insects enter the
house via the floor trap especially
GROUND FLOOR
3.
Floor Trap – SPIND Top Access Type
Top access type floor trap with bowl and bell cap with
features as follows:
 Easily removed and cleaned hence eliminate inaccessible
stains build up within the floor trap.
 Able to collect debris hence eliminating the debris to block
the discharge stack
 Cleaning eyes available to carry out rodding when there is
a blockage
 Water seal can be replenish automatically from the water
basin water
 Bowl bell cap components are easily available to replaced if
lost
 Side Flow for Concrete basin, water divert to urinal
4.
Water Basin
Identify the sources of smell from the water basin
4.1 Accumulated organic materials/debris inside the
water seal decaying emitting foul smell
4.2 Difficult or inaccessible areas within the water basin
ABOVE the water seal
4.3 Loss of water seal, applicable to P-trap type only
4.4 No water seal, allowing smell from the sanitary
system to enter the toilet
Conclusion
New Generation of Smelless public toilets can be built and
are sustainable provided the key points are adhered to:
- Design (fittings are maintainable and easy of cleaning)
- Thinking out of the box is necessary and DO NOT follow
the conventional method. More importantly use fittings
that are easy to maintain and clean like SPIND Top Access
Floor trap with cup and bowl features. This should be your
specification in your tender document.
- Cleaning Schedules of the public toilets
- Simple wet mop with mild detergents follow by dry mop is
sufficient!
- Education
- Users must be civic minded, treating the public toilets as if
their own home toilets

LIST OF PLASTIC PRESSURE PIPES
(Note: Internal Plumbing 3 to 4 bar system pressure)
UPVC – unplasticized polyvinylchloride ( length of 6 m)
CPVC – Chlorinated plasticized polyvinyl chloride
MuPVC – Modified unplasticized polyvinly chloride
ABS – Acrylonitrile butadiene styrene
HDPE – High density polyethylene (6m up to 100m length)
PPR - Polyproplyene
POB – Polypropylene Blend (classified as PP-B)
PE – RT, Polyethylene Raised Temperature
PE –X, Polyethylene cross-linked
PVDF – Polyvinylidenefluoride ( eg. PTFE, teflon)
Polybutylene – BS7291
JOINING METHOD OF PLASTIC PIPE
 Electrical Welding machine to heat up the pipe and socket and
press the soften components and hold, commonly known as
poly fusion welding
 Electrical Welding machine where both pipes are mounted on
sliding blocks on the machine, electro fusion sockets installed
and press start, machine takes over. Commonly known as
Electro fusion welding
 Solvent cement where both the socket and pipe has a coating
of solvent cement, both pressed together and hold for joint to
set
 Mechanical join, use of compression ring and with
mechanical force to tighten the nut forces the ring
against the butt end of the fitting, creates a high pressure
seal.

Solvent cement
ADVANTAGE OF SPIND PREZFIT
 Electricity voltage supply from generator set at project
site is unstable, this would affect the integrity of
electro fusion joints, lesser impact on poly fusion joints
 Solvent cement joints, dusty site condition would affect
the integrity of the joint and there is a need to apply the
correct amount of solvent cement on each of the joint.
Some skill required.
 Use of reel type of HDPE pipe up to 100 meter length
would reduce the number of joints compared with
solvent cement joint which is only 6 meter per length.
More joints means a likelihood of a joint leak is higher!
