What is a reduced pressure zone backflow preventer?

It is commonly known as an RPZ valve or a backflow preventer. RPZ is an acronym for a reduced pressure zone. It is a type of backflow prevention device used to protect water supplies from contamination in Villa Grove, IL.

Can a reduced pressure backflow preventer be installed vertically?

Backflow preventers must be installed in the installation orientation for which they were designed and approved (vertical, horizontal etc.). There are backflow preventers that can be installed horizontally, vertically (up or down) and other orientations that can make an installation easier.

Can you install a Watts backflow preventer vertically?

The Series 007DCDA may be installed in either a horizontal or vertical-up orientation for service on commercial potable water or fire sprinkler systems. Supply pipe lines should be thoroughly flushed to remove foreign material before installing the unit that may cause unnecessary check fouling.

What causes a backflow preventer to leak?

Why is my backflow preventer leaking? A. The backflow preventer is designed to relieve pressure when the watering cycle stops or the system is turned off, so you will see water dripping from it at system shutdown.

What is the difference between a regular backflow preventer and a reduced pressure backflow preventer?

The main thing to take away from this is that both backflow prevention device types perform the same function when they are operating properly, but only the RPZ is designed to protect the public water supply by disposing of any backwards-flowing water if any of the check valves or the relief valve fails.

Does a backflow preventer reduce water pressure?

What does a backflow preventer do? Backflow preventers are relatively simple tools when it comes to how they function. Their job is to prevent the flow of contaminants from the system to the supply line. And even if the pressure from the supply line drops dramatically.

Can a Watts 007 be installed vertically?

Can I use a check valve instead of a backflow preventer?

check valves. And we clear up a misconception that’s often inquired about in online forums: while check valves have other important applications, they cannot be considered a safe substitute for backflow preventers when it comes to protecting the purity of drinking water.

What pressure should a pressure reducing valve be set at?

Pressure reducing valves are required by code when the street pressure is higher than 80 psi.

What causes a backflow preventer to fail?

Backflow prevention assemblies are designed to provide decades of protection. There are many regional conditions that can shorten the working life of a backflow preventer. Conditions such as excessive pressure, water quality, temperature or turbidity can all cause the assembly to deteriorate in its performance.
