Installing a backwater valve will prevent sewer drains from backing up and overflowing with sewer water – eliminating sewer backflow as a source of basement flooding.
Backwater Valve installation Toronto
A backwater valve is a one way flow control valve installed in a drainage system, that under normal conditions allows the waste water to drain out of the system but if a reversal of flow should occur, the valve will be forced closed and protect the interior of the building from sewage backup. Every year thousands of homes are flooded with raw sewage and storm water causing millions in damages that could have been avoided with properly installed backwater valves.
When are backwater valves required
Backwater valves are required to protect fixtures and drainage openings that are installed below grade; such as in a basement, where the possibility exists for the municipal sewage or storm water systems to become overloaded and force waste water back through your drains. Backwater valves are also required on any subsoil drainage pipe that connects into the sanitary drain, to protect it from sewage backups.
The most common backwater points of entry into your home may be through basement floor drains, water closets, sinks, laundry standpipes and sump pits.
Fullport Backwater Valve
The Mainline #4963 Full-Port Backwater Valve is the ‘flagship’ of the company. Established in 1997, this valve has revolutionized sewer protection across North America with its patented ‘normally open’ gate design. This valve is typically installed in homes or buildings that have basements, cellars, crawl spaces or area that are accessible for servicing. The normally open gate allows the sewer system to ‘vent’ any gases that may be causes by positive or negative pressures in the sewer line. The 4963 has a ‘Clear View’ top that m
akes inspection of the valve quick and simple for the building owner or plumber! As well, the 4963 comes with an integral clean-out for rodding the sewer lateral. Should rodding from the stack be necessary, the snake can easily pass over the open gate and be retracted with out doing any harm to the components.

Built in flow channels on body direct sewage out of body
How Hinge area is protected from contamination
At the bottom of the valve you will notice dams, the gate in the open position rests on these dams preventing any flow from circling back from the outlet side of the gate and penetrating back into the hinge area,
At the front of the dams is drain port, this port drains away any water which may seep under the gate through the inlet side of the valve
Gate is fitted with closed cell polyethylene floats, this flotation material is impervious to sewage and will not become water logged (gate design locks floats in place)
Upon a slow reversal flow, water rises in the body and the gate starts to float (lift). Once the gate starts to lift the water flow in turn pushes the gate into the gate position.
Upon a quick reversal: The gate is fitted with 45 degree angles on the front which act as wings, upon quick reversal action water is diverted into the wing area through the flow channels. Water then pushes up on the 45 degree angles causing the gate to quickly close.
O-ring is used on the body for positive seal.
Built-in Sewer Cleanout
The built-in sewer clean out is downstream of the gate, a sewer tape will not catch on the gate when feeding or retrieving the cable
