    Pressure testers (advice please)

    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...

Because I have a job with poor flow rate which gets a lot worse when 2 or more outlets opened but 3bar (it's an unvented system so I was surprised at the poor flow rate) 2) I'm getting 16ltrs...
