obsolete parts?

So you pressure test it and it leaks - then what? Now refuse to fit a sealed system and keep ov - its still leaking which ever way you look at it. The damage has been done by you pumping it upto 3 bar

Erm....it gets repaired, it's part of the work to swap the system over.

Rubbish ... if it goes at 3bar then it was a burst waiting to happen and wasn't fit to be a sealed system and every customer I've done the job for has been grateful. They and I would prefer that it leaks when I'm on site and it gets repaired when I'm there rather than later down the line, when the system leaks and ruins their house.
