How much does a backflow prevention device installation cost?

November 15th, 2022

If you are a homeowner and are concerned about sewage or rainwater backing up into your basement, you may be wondering about backflow prevention devices, also known as check valves. This type of device protects your home from backflow and it is recommended that you call a plumber to install it. The following article will provide you with information on this type of device and the costs associated with its installation.

What causes sewer backups?

Sewer backups are when sewage or stormwater flows back into a property. This type of situation occurs in a variety of situations. For example, the side sewer may be clogged with grease, paper, household or organic waste, or a tree root. When the city’s collector sewer becomes overloaded, clogged or impaired, a sewer backup can occur. In the spring, river flooding or heavy rains can also cause this type of damage. A sewer backup will bring contaminated water into your basement. The risk of transmitting viruses and bacteria is therefore significant. Even when dried out, your basement may show signs of mold.

How does a backflow prevention valve work?

A check valve is an element installed on a pipe that controls the direction of water flow. The valve contains a shutter that acts as a door to prevent the return of wastewater. There are different types of backflow prevention devices such as the normally closed valve that is installed on each plumbing fixture drain pipe below street level. If there are several plumbing fixtures connected to the same drain pipe, the valve can be installed on the drain pipe only. The normally open valve allows water and air to always pass through. In the event of a sewer backup, the valve will lift and prevent sewer water from flowing back up.

How much will it cost to install a backflow prevention system?

There are several things to consider that will vary the price, but you can expect to pay anywhere from $1,000 to $2,000 (maybe more) depending on the work that needs to be done. It depends on what needs to be done, such as cutting out the basement floor covering or drilling into the concrete slab or digging around the drain. This type of work may involve cutting the drain pipe before installing the backflow prevention valve and then redoing the concrete and finishing. The price of the installation will also depend on the number of valves to be installed. The best thing to do is to contact your plumber and ask him to make an estimate. This will give you a realistic idea of the budget you need to budget for the work. Then you can rest easy knowing that you won’t have to deal with sewage backups in your basement.
