What is an RP backflow preventer?

The RP-500 Backflow Preventer is designed to supply maximum protection against back flow caused by negative pressure or backpressure. Backflow may cause infiltration of chemicals, fertilizers and/or other pollutants into potable water systems.

How does an RP backflow work?

RPZ backflow assemblies consist of two independent check valves. Backflow preventers work by letting water flow through them in one direction, but prevent water from flowing back through them in a reverse direction. This is how the water supply is protected.

What is a RPZ backflow device?

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.

What is the most reliable backflow prevention device?

RPZs
Reduced Pressure Zones (RPZ): Primarily intended for plumbing and other internal systems, RPZs are the most complex and reliable backflow preventers. These devices consist of a shutoff valve, two spring-loaded check valves separated by a pressure differential relief valve, four test cocks, and an outlet shutoff valve.

Can an RP be installed underground?

The RP must not be installed in a vault or pit or any structure where the assembly could be submerged. Both the UPC and IPC prohibit test cocks from being installed underground.

What’s the difference between an RPZ and a backflow preventer?

A Reduced Pressure Zone (RPZ) lets you know that the valve is working properly. RPZ backflow preventers consist of two independent check valves. Backflow preventers work by letting water flow through them in one direction, but prevent water from flowing back through them in a reverse direction.

What is the difference between check valve and backflow preventer?

Check valves are used in a wide variety of equipment, cars, planes, pneumatic and fluid systems, while backflow preventers are typically used in plumbing systems for structures. A check valve has a variety of roles but is mostly used to regulate and control the flow of fluids, especially into pumps.

What is a plumbing backflow device?

A backflow preventer valve is designed to prevent the water in your main water supply lines from flowing in a reverse direction. The valve will distribute the sanitary water from the main supply pipes to the water lines beneath your foundation.

Which plumbing device helps prevent a backflow Servsafe?

A vacuum breaker is a mechanical device that prevents backsiphonage. It does this by closing a check valve and sealing the water supply line shut when water flow is stopped.

Why are backflow preventer above ground?

USC Supports Installing Backflow Preventers Above Ground The reason for this recommendation is the safety of the public drinking water. When a backflow preventer is installed below grade, the vault or pit in which an assembly is installed may fill up with water — possibly contaminated water.

Can a backflow preventer be underground?

You should have your backflow prevention assembly installed inside an above-ground enclosure. You also don’t have to worry about flooding your building if backflow were to occur and your backflow preventer does its job. Installing a backflow preventer underground is not safe.
