PSI BAR whatever, need to see if my bodge will work

[Gaffers]

at a guess I would say about 30-40 psi, but I am sure someone with more scientific knowledge will give you a better answer soon  

[Kevin Wood]

It's not too high. Perhaps 10 or 12 PSI. I forget what the expansion tank cap is rated at but it may be stamped on it. That's the ultimate limit to the pressurisation.

12 ish Psi....

12 ish Psi....

Will alradite hold a copper pipe glued into a nylon pipe?

I hope so as I need to hunt for a new T piece

Chose the right araldite, it has a habit of softening when warm and roughen it all up well first so it gets a good key.

Couldn't find slow set and rapid didn't work - have some 2nd hand tees on their way!

Hi,
Some while back I made up a tee piece with Schreader Tyre valve in it so I could fit in the system to pressurise it cold to check for leaks.

I found the header tank pressure cap started to release at just over 13 PSI.
