Sudden rain could cause sewage to flow backward into your house. A sewage water backstop is a great way to prevent backflow, as it ensures sewage can only flow in one direction. Installing a backstop is an effective way to flood-proof your house.
How Do Water Backstops Work?
Sewage is supposed to flow out of your house. However, if the main sewer line is overwhelmed, it can get backed up, resulting in sewage flowing back into your house and flooding the premises. Having a basement makes it more likely you’ll experience flooding.
A sewage water backstop is a valve installed in your sewer. Normally it lies along the pipe floor, but when water backs up toward the home, it’s pushed upright so sewage can’t flow backward.
Some houses come with backstops. If your home doesn’t already have one, you will have to apply for a plumbing permit to install a new one.
Should You Get a Backstop?
Consider installing a backstop for the following reasons:
- You experience frequent flooding.
- You live along a storm line, where there’s a constant risk of bad weather.
- You have a basement.
Installing a backstop can prevent the headache of property damage that accompanies sewage flooding. A little bit of foresight can go a long way in protecting your home.
