Looking for some advice here.
Went to see an existing solar thermal system installed 10 or so years ago it has soldered connections - allowed at that time iirc.
Anyway custard is having lots of work done including installing a new unvented dhw cylinder and has asked us if we could drain down, disconnect it from the existing cylinder, hook up to the new one and re-commission.
Generally it's in pretty good condition, and I've checked all the existing joints and they are OK.
So long as the required safety's are in place which in this case is just, the manual reset and check valves. What is your guys take on installing the new pipework to current regs - in this case it will be compression with brass olives from the point it comes into the 'airing' cupboard, and leaving the existing pipework that is working just fine as it is?
I can't see much point in ripping out all the existing which is working OK, even if we wouldn't do it that way now on a new system. (Obviously we'll do all the pressure and saftey tests etc when we re-commission with nice new glycol)
