Size Forged Steel Check Valve 2012-03-12

A Tilting Disc Check Valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction.

These valves are often designed for safety reasons, to prevent backflow and to ensure that someone operating a system knows which direction fluids and gases are flowing in. Check valves can also be used for tasks like creating leak tight seals, which can be an important safety or convenience future. They are also used for the routine task of directing fluids or gases efficiently through a system.

1 Turn off and disconnect the power source to the pump before attempting to do anything with it to avoid electrical shock.

2 Remove the old check valve from the intake if you are replacing it.

3 Check the manual of the pump if you still have it, or the specifications for your make and model online. These sources will specify the inlet connection size.

4 Measure the inlet pipe or the outlet of the old Forged Steel Check Valve across the widest point to get the diameter if you cannot locate the specification.

5 Write the measurement down and keep it with you so you have a reference when shopping for the new check valve.

Check valves prevent the back flow of liquid or gas. Sprinkler and irrigation pumps often use check valves to stop water from draining out of the pump body when not in use. If the water flows out, the pump may require priming before it will siphon water again. Check valves are also used to prevent back flow contamination of water supplies to prevent flooding and prevent flow due to gravitational forces.
