I've never bothered with pressure testing before because my soldering is normally pretty good. I'm currently doing a full system from scratch though and the builder got all the materials. Bar the tails the whole lot is in barrier and I'm not happy with a lot of the joints. I have a horrible feeling it's going to sound like the 1812 overture with joints popping everywhere. I therefore popped out today and grabbed a Stanley compressor but think I'm going to have to adapt the hose end to fit a bit of 15mm. Has anyone used these or the proper rothemberger hand one? It's only 8 dads but I don't fancy sitting there with the rothemberger one pumping away for an hour to pressurised it. Any experience you have with either of them would be welcomed. Ta.
