Notes :
1.
All water meters shall be installed in the horizontal position. By-pass piping may be installed
in either the horizontal or vertical position around the water meter. The inlet tee shall be
installed within 500 mm from the floor or wall where the private water service pipe enters the
building.
2.
Water meters shall be installed with a minimum 1.2 m unobstructed clearance in front of water
meter to nearest wall and 300 mm unobstructed clearance behind the water meter to nearest wall.
Water meters shall not be installed at a height greater than 450 mm above the floor.
3.
By-pass piping shall be installed with a minimum 300 mm unobstructed clearance from the outside
wall of the by-pass pipe to the nearest ceiling or wall.
4.
The working space in front of the meter shall have a minimum of 1.8 m unobstructed head
clearance.
5.
All joints shall be soldered, compression type, threaded or welded. Acid core type solder is not
permitted. Solder-joint fittings for copper pipe shall conform to ANSI B16.
6.
All piping, including by-pass pipe, tees, bends and valves, shall be the same diameter as the
private water service pipe.
7.
The by-pass and flushing valves shall remain closed at all times and shall be sealed by the City
after water meter has been installed.
8.
Only gate valves shall be permitted for inlet, outlet, by-pass or flushing valves. No ball
valves or butterfly valves shall be permitted. Gate valves shall be designed for a minimum cold
water working pressure of 1035 kPa and shall conform to CSA B125.
9.
Drainage valve shall be a brass ball valve with brass plug.
10.
All piping shall be either type "L" copper (certified to ASTM B88) or stainless steel pipe
rated to a minimum working pressure of 1035 kPa. For stainless steel pipe, all pipe flanges shall
be welded to the pipe. Galvanized, polyethylene, PVC and other plastic pipe and fittings shall not
be allowed.
11.
All check valves, backflow preventers, pressure reducing valves, cross connection control
devices and all other such devices shall be located downstream of the outlet tee. No other fittings
or connections shall be allowed upstream of such devices.
12.
All water meter installations shall conform with the manufacturers installation instructions.
13.
The by-pass valve shall be connected to the inlet tee, the flushing valve shall be connected to
the outlet tee and the drainage valve shall be connected to the flushing valve. The drain port tee
shall be connected to the upstream side of the outlet valve. All valves shall be configured such
that their handles shall not interfere with each other and all valves shall be readily accessible
for operation, repair or replacement.
14.
Any insulation placed on or around any water meter shall be easily removable and replaceable
and shall not contain asbestos or any other toxic or hazardous materials. Such insulation shall not
cover or obstruct the water meter register. The City shall not be responsible for any damage to
such insulation during any removal or replacement of such insulation.
15.
The room where the water meter is located shall be positioned in the building such that it is
adjacent to the outside wall of the building at the point where the private water service pipe
enters the building.

16.
The room where the water meter is located shall have a door with a minimum opening of one metre wide
and 2.2 m high. The floor, shall be constructed of waterproof materials. The walls and ceiling shall be
constructed of water-resistant materials.
17.
The private water service pipe shall be flushed prior to and after the installation of the water
meter.
18.
For remote readout device wire and conduit installation, refer to City of Toronto specifications.
19.
When non-metallic pipe is used for the private water service pipe and / or private water pipe
downstreamof the meter, the section of pipe between the stop and waste valve and full bore
ball valve shall be as per note 8 above and shall be fully supported and restrained to prevent
movement of the piping around the meter.
All dimensions are in millimetres unless otherwise shown.
