Air- test a system of water pipes by turning off the main shutoff valve and draining the water from the system.

How long should you pressure test pipework?

How do you pressure test PVC pipes?

Use the attached pressure test tool to put water in the PVC lines . The lines should be mostly full of water and not just air. Remove one of the plugs if necessary to fill the pipes with water then reinstall the plug. Continue to add water until the pressure reaches 20-25 psi.

How do you pressure test a shower plumbing?

If you’ve installed a combination shower and tub valve , remove the tub spout and cap or plug the line. This will allow pressure to build up in the water lines when the faucet is turned on for testing . Leaks that might not appear when water is flowing through a faucet will emerge when the valve is under pressure .

How do I test the air in my sewer line?

Connect the air hose to the inlet tap. Add air slowly to the test section until the pressure inside the pipe reaches 4.0 psig. Allow the pressure to stabilize such that a pressure between 4.0 psig and 3.5 psig is maintained for at least two minutes.
