Pressure Test Guide.

DiaOseal performs a pressure test and full tap service on every shower as part of our Standard Seal Service.

1. Steps

• Unscrew the shower rose off the wall and clean any teflon tape or similar from the thread.

• Screw pressure gauge hose onto the thread that comes out of wall.

• Turn on the cold tap, pressurizing the gauge.

• Check with your torch through the spindle penetrations for leaks from body washers and any leakage dripping down from the shower rose behind the wall.

• Watching the gauge turn the cold water off. The needle should remain in the same position. If a leak is present the needle will drop due to pressure loss within the gauge as a result of this leak.

• With the cold water off, turn the hot water spindle on and check the body washer for leaks.

• Should your test reveal a leaking pipe, STOP and call the office.

• Should your test reveal a leaking body washer, don’t worry as you will be performing a tap service anyway. (As per tap service guide.)

General Information.

You will not be able to carry out a pressure test on a gravity feed hot water system. If you find a leaking body washer on the hot water side, inform the client that a plumber is required to change the washers as soon as possible.
