What Does a Backflow Preventer Do?

When water flows into your home through the main plumbing line, it usually flows in a forward direction. When plumbing problems occur, water can flow backwards and lead to all sorts of damage to your home and can also cause health issues.

Backflow can happen in your water system when there is back pressure or possibly back-siphoning in your plumbing system. It can also be caused when your town or city’s water supply experiences dropping water pressure.

If you find you have a problem with your backflow preventer, you will want to contact a 24 hour emergency plumber in Virginia Beach as soon as possible. Backflow can lead to contamination of your water supply. Installing and maintaining a backflow preventer is imperative to keeping your water supply clean and free of contaminants.

What Is a Backflow Preventer?

A backflow preventer is a device that is installed where the main water supply enters your home. It helps prevent the water entering your home from becoming contaminated from any water that may start flowing backwards. Most devices use a ball that is a little bigger than the supply line. The water pressure forces to ball to open and let water through and is connected to a spring that helps keep the ball in the shut position when no water is flowing.

This closed position prevents any water from backflowing, stopping things such as chemicals or fecal matter from flowing into the water supply.

Backflow Preventer Testing

It is important to have your backflow preventer tested every year. You may even receive a letter from your local council requiring you to submit a testing report. This will ensure that your backflow preventer is functioning correctly and has not failed. Virginia requires that this testing be completed by a certified professional.
