Eliminate Back-flow in Main Drain

Toronto receives heavy rainfall every year. Naturally, this causes sewer backflow throughout the city. The municipal sewer system can often back up, causing the home sewer drains to choke up. The result: a flooded basement. Fortunately, the city provides up to $3,200 in aid in installing flood prevention devices at homes, including a backwater valve.

A backwater valve installation in Toronto is the best insurance policy against the backflow backflow of sewer water. Mechanically, it is a one-way valve, meaning water cannot return to the home. As per Toronto Plumbing law, every modern household should install built-in backwater valves during construction. Many homes constructed decades ago face basement flooding due to sewer backflow. The flooding of a basement can get costly. It certainly is a traumatic experience. In bad weather, water damage can cost an average homeowner up to $25,000. So, it is a good idea to prepare in advance and prevent the loss of personal property. For more information on backwater valve installation costs in Toronto, reach out to us today.

The backwater valve is an essential component of the home plumbing system.

It prevents sewer waste from overflowing or backing up into the home. It helps eliminate sewer backflow, which backflow could lead to basement flooding.

Do You Require Backwater Valve Installation in Toronto?

Most homeowners already know whether or not a backwater valve is required. Flood-prone homes definitely cannot do without one. If the sanitary sewer drain is located at the top of a hill and homes are all down the slope, the chances of sewage backup increase dramatically. A home situated downhill should install backwater valves. Regretful homeowners are looking at basements flooded with sewage waste.

An innovative plumbing contractor in Toronto developed it. Earlier, plumbers installed check valves on every sewer back line. So, every drain had its own backflow backflow prevention valve. It meant that the house was littered throughout with backflow valves. They were all over the house. It made repairs difficult due to multiple out-of-sight valves. These valves were also likely to be damaged during drain snaking. The large number of valves made it challenging to identify the faulty one. Most people realize a faulty valve only after the basement has been flooded.

Enter the backwater valve. It is installed on the home’s primary sewer line, eliminating the need to install several check valves throughout the property. In its natural open position, it permits the outward flow of sewage and the venting of gases. This position allows unobstructed wastewater flow. On the contrary, this one-way valve closes if the sewer water flows in the reverse direction, as is the case with flooding.

The invention of the backwater valve is a piece of Canadian ingenuity!

Backflow is a generic term that applies to various plumbing fixtures. So, people often ask about the difference between a backwater valve and a backflow preventer. Let’s clarify this once and for all.

A backwater valve is used to prevent sewage water from the main drain pipe from backing up in the home.

It is installed on the main sewer pipe to prevent basement flooding. On the other hand, a backflow preventer acts against the general backup of water through any line. Under normal pressure conditions, the water lines do not back up. However, under pipe bursting, the pressure in the line drops, leading to water and contaminant backflow. To prevent this, a backflow preventer is installed at high-risk plumbing joints.
