Re: Dave Robs laser Cut Ball lifter
I'm not convinced about the long term reliability of these push-fit connections. I expect them to be OK for cold water connections where there's no likelihood of movement, but can't see them being appropriate for copper pipes with hot water. There is going to be some degree of thermal expansion when the hot water is running through the pipes, and contraction when it all cools back down to room temperature afterwards. This movement is likely to be taken up by the o-ring seal in the fitting and so it may prematurely wear.
Seeing as a failed rubber seal allowing water to drip onto the floorboards caused this entire dry-rot mess to occur in the first place, I don't think I'll be trusting an o-ring seal for a little while yet!
As I've already got the fittings, solder, flux and a blowtorch from previous DIY plumbing attempts, I think I'll be using the old tried and tested copper pipes with soldered joints, and not have to worry about it springing a leak, with the added bonus of there being no restrictions to the flow of pachinko balls.
