Plug or seal any open ends and use valves to limit the test section of the piping.

Step 1 –  Plug or seal piping

Plug or seal any open ends and use valves to limit the test section of the piping. Using valves to limit the test section means that you can test a certain part of the piping, depending on where the valves are placed.

Wonkee Donkee says, "To plug or seal any open ends, use pipe plugs or stop ends."
Pipe plugs and stop ends are used to seal off the ends of copper and plastic pipes while testing. Both can be purchased in a variety of sizes to fit pipe with different diameters. Pipe plugs and stop ends are used to seal off the ends of copper and plastic pipes while testing. Both can be purchased in a variety of sizes to fit pipes with different diameters. Ensure there is no burr on the pipe end before fitting a plug or stop end. Burr is a rough, sometimes jagged, edge left on the inside and outside of the end of a piece of pipe after it has been cut. Remove burr with abrasive paper, a file or a special attachment on some pipe cutters.
Insert the pipe plug into the end of the pipe. Once the end of the plug is inside the pipe turn the wings clockwise to tighten the plug. Insert the plug into the end of the pipe. Once the end of the plug is inside the pipe, turn the wings clockwise to tighten the plug.
The stop end will mount the open end of the pipe. This will then be pushed against the pipe to lock in place. The stop end will mount the open end of the pipe. This is then pushed against the pipe to lock it in place.(To remove the stop end, push the collar into the fitting and pull it off the pipe.)
Use the push fit fitting to connect the test gauge to the piping. Simply insert the pipe into the fit fitting to lock the pipe clamp around the pipe securing it in place.

Step 2 – Connect test gauge

Use the push fit fitting to connect the test gauge to the piping. Simply insert the pipe into the fitting to lock the pipe clamp around the pipe, securing it in place.

Once the testing gauge is in place, you are now ready to pressurise the system.

Step 3 – Testing kit is ready

Once the testing gauge is in place, you are now ready to pressurise the system.

Use a hand pump, foot pump or an electric pump with the correct adaptor to apply pressure to the system.

Step 4 – Pressurise pipe system

Use a hand pump, foot pump or electric pump with the correct adaptor to apply pressure to the system.

Each of these pumps would require a schrader pump adaptor. Each of these pumps would require a schrader pump adaptor.
Place the pump's adaptor onto the end of the schrader valve by pushing and screwing the adaptor clockwise onto the valve. Push and screw the adaptor clockwise to fit onto the schrader valve. Screw the adaptor until it is hand tight. Place the pump’s adaptor onto the end of the schrader valve by pushing and screwing the adaptor clockwise onto the valve.
Pump air into the system while watching the dial. Make sure enough air is pumped into the system so the needle points to 3 - 4 bar (43 - 58 psi or 300 - 400 kPa). Pump air into the system while watching the dial. Make sure enough air is pumped into the system so the needle points to 3 – 4 bar (43 – 58 psi or 300 – 400 kPa).
Retain the test pressure for around 10 minutes to see if there is a drop in pressure. You can leave the test for however long you like but the minimum recommended test time by professionals is 10 minutes.

Step 5 – Time test

Retain the test pressure for around 10 minutes to see if there is a drop in pressure. You can leave the test for however long you like, but the minimum test time recommended by professionals is 10 minutes.

After the time has finished and there is no drop in pressure then the test is a success.

Step 6 – Check drop in pressure

If, after 10 minutes, there is no drop in pressure, the test has been a success.

If there is a drop in pressure then the test was not successful. If there is a drop in pressure, then the test was not successful.See How to fix a drop in pressure?
