A check valve lets water flow one way and blocks it from flowing back. It is a simple flap or ball that does its job automatically, with no handle to turn.
The one way
Inside the valve, a disc, ball, or flap sits in the flow path. hard water is common, and summer heat and shifting soils put pressure on underground lines In Brownsville, water pressure on the inlet side pushes it open, and reverse pressure snaps it shut.
The gravity
Some check valves rely on gravity to close the flap when the flow stops. A vertical installation lets gravity help the seal.
The spring
Spring-loaded checks close faster and work in any orientation, which is why pumps and appliances use them. The spring adds a little resistance to the flow.
The uses
Sump pumps, ejectors, boilers, and irrigation all use check valves to stop backflow. hard water is common, and summer heat and shifting soils put pressure on underground lines In Brownsville, the sump's check valve keeps the pit from refilling.
The failure
A stuck-open check lets water flow backward, and a stuck-shut one blocks the flow. A rattling valve often means the flap is loose or the spring is tired.
The check
