Example Back Flow Devices

This page is provided as an aid to help members identify devices they may have, that need to be tested. It is not intended as an exhaustive list of all devices. 

Sprinkler Systems

An in-ground sprinkler system is buried beneath the ground surface and usually consists of pop up sprinkler heads. In-ground sprinkler systems can be connected to the water source at the house, by the water meter or anywhere in between.  A backflow assembly should be located at the water source and could be buried in an access box or mounted above the ground, on the side of a house or maybe the deck.

Pools and Hot Tubs

Some Pools and Hot Tubs have auto-fill connections to your water supply. These connections must have a back flow device.

Frost Free Hydrants

Example of frost free hydrant without anti-siphon adapter. This frost free does not meet CCCP requirements.

Example of frost free hydrant that has a anti-siphon adapter added. This frost free meets CCCP requirements.

Frost free hydrants are convenient ways of having year around water at different locations on your property. Frost frees do not come with anti-siphon adapters when purchased, they must be added separately.

Medical Equipment

Some medical equipment used at home such as dialysis machines can be directly connected to your water source. Medical equipment such as this must have the proper backflow prevention assemblies in place. If you are unsure, please call our office so we can inspect your premises and make the correct determination
