Testing a Water Line Check Valve
A check valve may be installed in a house water line in order to regulate water entering and exiting. Though a check valve in a water line requires little external interference, it is important to test the check valve every now and then to ensure the correct water pressure is entering the home. To test the check valve, begin by opening the high-side and low-side bypass valves. Then attach the high-side hose on the test kit to the fitting, which is usually to the left side of the check valve.
The low-side of the hose from the test kit should be attached to the testcock to the right of check valve. Turn off the first shut-off valve (connected to the water line) and then slowly open the testcocks to which the hoses are attached. Open the high-side bleed valve and then close the low-side bleed valve. Read the PSI on the test kit to see if the water pressure is where it needs to be.
Backwater Check Valve
There are different types of check valves. The one type that you will want to make sure that it is working in excellent condition is a backwater valve. This type of valve is used for sanitary drainage systems. If you have ever had a sewage backup then you know exactly how important it is to make sure that this type of valve is functioning properly.
A backwater check valve protects lower located rooms against flooding caused by return flow of sewage waters. Backwater valve prevents rodents and rats to enter the sanitary and rainwater drainage system as well as the building interiors. Preventing a sewage blockage is something that is important to prevent. The smell is un godly as well as the clean up.
Check Valves
The check valve is designed to use in sanitary stainless steel pipe systems. The check valve is responsible for preventing the reverse product flow. This valve is versatile because it can be installed either vertically or horizaontally. Pictured here is Alfa Laval’s “Y”-Body check valve.
