So if I understand correctly, the consensus is: It was bad practice to fit the pipes like this and it does increase the risk of leaks in the future, but still we'd have to be unlucky for a leak to occur if the fittings we properly pushed home and pressure tested. Given the plastic pipes are already joined this way and its already concreted over, there's not much we can do? So really, we should leave them in place and either get a properly documented pressure test done and/or get the situation documented in writing with a clear responsibility for the builder to rectify if repairs are necessary (the builder has been around for 12 years - realistically this will be hard to enforce if it fails many years in the future and/or if the builder closes down - but it probably strengthens our hand if the pipework fails in the near future).
Do people agree with the above? Or any other constructive suggestions on options we have given where we are?
