Help Please. Has anyone heard of testing a sealed system using high pressure (8bar) as a method of sealing push fit polyplumb connectors that may not have initially installed properly and were leaking. We have recently had a massive underground leak in a new build that initially showed pressure loss during testing at 1.5bar but then was tested a 8bar and miraculously the leak seemed to have disappeared thereafter. The damage is massive and although drying out now, the insurance company wont pay out because current leak detection shows no pipe leak. Any advice would be greatly appreciated. Regards jhk
