Today’s homeowners are extending their living space by utilizing the basement area. Whether you use the lower level of your home as a game room, office, exercise area or workshop, you’ll want to be sure the area stays moisture free. While you may not have spent a lot of time wondering about backwater valves, installing one of these fixtures can be a key component to making sure your basement remains dry. This is definitely a labor-intensive job and may require some professional expertise, but this guide will help you understand why you need one.
Backwater Valve Defined
Also known as a back-flow prev-enter, a backwater valve prevents storm water or sewage from backing up in drains or plumbing fixtures. It is installed under your basement floor and attached to the main lateral drain line. Any time a reverse flow of waste water occurs, a gate flap closes to prevent it from backing up.
You may have seen a backwater valve in the plumbing supply section of your local specialty store. They are usually made of 4″ ABS plastic pipe with openings on both ends. These openings allow for the inlet and outlet of waste water. A closed-cell polyethylene gate with flotation devices on either side is resistant to sewage and won’t become water logged. The top is usually made of clear plastic so a visual inspection can be made periodically to check its operation.
