Hi,
I'm thinking ahead when I go to install my new Combi boiler
pipework.

I obviously have to pressure test the pipework, to ensure the pressure
relief system works.

What test method is best - dry or wet?

I've noticed Screwfix sell a "dry pressure test gauge" with a Shrader
valve.
Obviously this will only allow to test using pressurised air.

I've noticed some posts on the newsgroup about the dangers of dry
pressure testing.

Can anyone give an opinion on the better methods, and tools to buy.

Thanks,

W.
