Pressure testing

[stratplus]

On new build it was standard to test the first fix to 18 bar, had to be witnessed by the site agent then a certificate issued saying what pressure was applied and how long for.
When completing second fix and filling up it became obvious who hadn't tested properly with water leaks all over the property, ceilings/walls showing damp patches or worse.

I first fixed a 1 bedroom flat in copper last week. I air tested to 8bar but the pressure kept dropping slightly but I couldn't trace any leaks so I filled with mains water to 2 bar and a ball o fix valve popped off! With water going everywhere! Turns out it was only leaking very slightly originally on a speed fit cap end.

18 bar is pretty standard stuff on alot of plastic installs. Ive tested speedfit to 25bar with no failure just to see what would happen.

air testing is dangerous and should be done with caution and no other persons inside the building.


its alwasy good to get the new apprentice to cut a pipe at 18bar to take it off test, they always get wet and a good shock.

the only reason I test isto make sure there wont be any water leaking everywhere, if done in copper there is very little chance that it will leak after a test and even less chance of it leaking 6 months down the line. and if air testing I would rather it flew off and then I know I hadnt done it right.

I dont get the whole water testing, if you have a leak then you will have water pooring everywhere.
