So you know again we always most pumps have a check valve in them. But you know depending on the manufacturer.

RP's must be installed above ground. Backflow preventers installed inside must be a minimum distance of twelve (12) inches above the floor, and no higher than four (4) foot above the floor, with adequate clearance around the backflow preventer for testing and/or repair.

This check valve will be the first check valve installed. The second check valve should be placed above the pump and no more than 25 feet above the water pumping level in a well. This will ensure that if the check valve at the pump fails, the second check valve in the system will hold the vacuum below it.

The Manager shall inspect and approve all installations of the required backflow prevention devices. The costs for purchasing, installing, and maintaining a backflow prevention device shall be the responsibility and sole expense of the consumer. The consumer shall the backflow prevention device.

Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a one-way valve, in which the flow can run freely one way, but if the flow turns, the valve will close to protect the piping, other valves, pumps etc.

Backflow testing is a plumbing service that checks your backflow preventer device by assessing its pressure levels. When backflow is present, untreated or contaminated water can be back-siphoned into your clean water. For this reason, testing guarantees the water you use for drinking and showering is safe and sterile.

pump, check valves and backflow prevention devices or assemblies shall be located a minimum of 10 pipe diameters from the pump suction flange.” The 10 times the pipe diameter requirement is to minimize the turbulence created by the check valve.

Check valves use a hinged plug that allows water to pass through the pipeline but blocks it from coming back. Backflow preventers, on the other hand, apply an increased amount of pressure on a pipe to ensure the water can only flow one way.
