Pvb Backflow Test Procedure

Pvb Backflow Test Procedure

A backflow preventer is a device that keeps water from flowing backwards into your drinking water supply. A backflow preventer is installed in your home or business to protect your water supply from contamination or pollution.

The purpose of a backflow preventer is to protect your drinking water from contamination. A backflow preventer is installed in your home or business to keep contaminated water from flowing back into your water supply.

There are two types of backflow preventers:

• Reduced Pressure Zone (RPZ) Backflow Preventer
• Double Check Valve (DCV) Backflow Preventer

The type of backflow preventer that is installed in your home or business will depend on the type of water supply you have and the level of protection you need.

If you have a private well, you will need to install a DCV backflow preventer. If you have a public water supply, you will need to install an RPZ backflow preventer.

You should have your backflow preventer tested once a year by a certified backflow tester. Backflow preventers can become damaged or corroded over time and may need to be repaired or replaced. A backflow preventer test will ensure that your backflow preventer is working properly.
