Purpose of pressure test on speedfit system?

[GCarnegi]

Obviously to prove that a system doesn't leak.

I'm pretty sure my plumber did NOT pressure test my plastic pipe CH system when he commissioned it last night.

I'm just curious as to whether the 10 bar pressure ONLY tests for leaks, or actually has some "setting" action on the fittings - making the teeth bite-in a bit harder, for example. I know it won't have any lasting effect on the O-rings.

So does the lack of a pressure test actually make a system less reliable, or just makes it... err... untested?

Is it common practice NOT to pressure test a plastic system?

If it was common practice, would anyone openly admit that on a web forum?

Just curious

Depends how good his/her public liability insurance is.

I would certainly notify him/her in writing that it hasn't been tested according to the manufacturers and date it and keep a copy.

If you have a flood you may find it quite handy.

If it's not been pressure tested correctly and there's a warranty issue with the fittings or pipe, they won't honour the warranty.

Part of the reason for the 10bar test is to push the pipe and the grab rings of the fittings into each other to make a sturdier fit.

If there is a fault, JG will come and disassemble some fittings and walk away laughing all the way home.

Bit of a cop out IMHO, but thems are the terms.

Plastic is for monkeys.

It proves it's capable of withstanding 10 bar. A leak test is not the same as a pressure test.

So when they sell them in diy shops do they honestly expect them to be tested dont see anywhere in shops that explains this
Should they not be described as pushfit but pressure sealed false marketing in a way

That's why is said it was a cop out...

But how many manufacturers of cheap shlte will do cartwheels to help you in a warranty situation?
