I am redoing my en-suite and I am considering using pushfit connectors. For part of the installation I will need a couple of 90 degree bends (15mm) that will eventually end up covered over in a plasterboarded wall. Obviously I will make sure they do not leak before covering them up, but is this a good idea or am I better to use compression joints here (my soldering is not very good!). Has anybody seen any details on the expected lifespan of pushfit or are they expected to last 'forever'?
Cheers
John
