Backwater Valve & Sump Pump



Sump pumps are extremely effective at controlling water leakage, redirecting it out of your basement.

HomeStars Review Our Work



A sump pump is something we highly recommend to our clients, a highly effective way of redirecting water away from the foundation and footings of your home, ensuring your basement stays dry.

A sump pump is usually installed so that the weeping tile system that surrounds the perimeter of the house has a place to drain.

The old method of draining a weeping tile was to connect it to your drainage system. But that is deteriorating and cannot keep up with the increase in precipitation we are now seeing. This situation if left unchanged will almost guarantee that your house would eventually get flooded in the event of a major storm.


The global climate is ever changing. We are seeing more examples of this right here in Southern Ontario. Heavy rains and snowfalls are overwhelming the aging sewer infrastructure across our community. One of the unfortunate byproducts of the increase in water has been flooding in neighbourhood homes.

Residential basements have been particularly impacted. There is little the homeowner can do to protect their homes against such extreme weather-related flooding – if their home isn’t waterproofed.

In 2013 the insurance industry spent almost $1 billion repairing and replacing clients’ basements and possessions. That’s the bad news.

The good news – there is a solution to keep basements dry and avoid this level of property damage or loss. The pros at Canada Waterproofers Brampton will visit your house and give you a free assessment of the waterproofing, plumbing or drain repair work needed for your home. The best offence is a good defence – we’ll show you how to protect your property from any future flooding with the latest in flood protection technology.

When a sump pump is installed the old weeping tile connection to the city sewer is severed. That will help avoid flooding.

We also highly recommend installing a sewer back-up valve (backwater valve) to protect you from sewage coming back from the city.

The pump is installed inside the basement along the wall – as long as there is a place to discharge the water (so the water doesn’t flow back into the house). Our crews will excavate, remove and dispose of the soil, and install a water tank (also called a sump liner).

We’ll then set up a connection from the existing weeping tile (or the new weeping tile, if installed) to the side of the tank. We’ll encase the tank with gravel (3/4″ clear), re-cement around the tank, install a submersible pump, then test the system (discharge water to the exterior). If all checks out and meets our standards, a lid is then put on the tank, bolted down, and you are good to go.

A sump pump consists of three main features:

  • Tank that holds the water that is drained from a weeping tile
  • A pump that pushes the water up and out of the basement to a drainage point
  • There is also a third feature that can be added to the sump pump – a battery back-up system and alarm


This system consists of a separate pump that runs off a marine battery, so if there is a power failure or a primary pump failure, you are still protected, since the back-up pump will automatically switch on. The back-up device can continue to pump water out of your basement without the aid of the main power for up to 24 hours.

The system also features an alarm that automatically switches on when the battery pump kicks in, so you’ll be aware when the main pump is not functioning.

We recommend the extra security that the battery back-up provides you, if you are leaning towards having a sump pump installed in the home.


We love this pump. This one is powered by your water supply, kind of like fighting fire with fire. Water turns the pump turbine which then pumps water out of your basement.

Plus with this pump there is not a time limit as to how long it will run. As long as your water supply is on then the pump will keep on pumping.

There is one thing to bear in mind, though.

You need a minimum 3/4″ water supply line from the city coming into your house in order for the pump to work correctly. If you have the supply line, and it’s close to your sump pump, then this is the ideal way to go, as it’s one of the most reliable pumps on the market and doesn’t use up any power.


A backwater valve is a device that prevents outbound water from the home to re-enter through the home’s drain pipes. The valve prevents raw sewage from backing up into the home through toilets, sinks, and showers.

Municipalities and insurance companies are now encouraging homeowners to install mainline backwater valves.

  • The installation of the valve takes just one day
  • The valve can be installed either inside the foundation wall or outside of the home entirely
  • Our crew will conduct a camera inspection of the sewer to determine the ideal location for the valve
  • Once the valve is installed it will allow waste from the home to flow to the city main
  • If for some reason the city main becomes overwhelmed and begins to back up into the adjacent basements, the valve will close automatically, preventing flooding from the city main sewer

The professionals at Canada Waterproofers Brampton have expertise in installing backwater valves, and would be happy to provide an on-site assessment and a free quote.


A crew from Canada Waterproofers Brampton will excavate where the sewage connection leaves the house (normally in the front of the house), inside or outside the foundation wall. The building code stipulates that the valve has to be within a maximum of three feet from the front wall and you cannot have a Y Pipe connected within three feet behind the valve, or you risk having the sewage back up into the house.

Install the city-approved BWV with down-stream, clean-out access in the front of the valve. Have the valve inspected by the city. The Canada Waterproofers Brampton crew will support the pipework with gravel and then back-fill and compact the ground, followed by inside concrete finish and outside gravel finish. Clean-up is the last step.

Check out our drain section to read more about backwater valves and how important they are for flood protection.

Keep in mind – when installing any new fixture a permit from the city is required. Ask us about it.
