Push-fit plumbing. I’m not happy with what the kitchen fitter did, and want him to change it.

My concern about push-fit is potential failure of the gasket forming the seal between the components.  I don't have any idea what the life expectancy of that item is, but would expect a well made solder joint to be a permanent seal.  Not so sure about that with push-fit.

John Guest, the manufacturer of the SpeedFit fittings, have increased their lifetime warranty from 25 years to 50 - That should give an indicator of how long the fittings will last if installed correctly and not subject to extremes of temperatures.

We had a weep on a soldered joint in our bathroom. The entire GCH system needed to be drained down to fix it. 

I know a soldered joint can fail but I just suspect that it will be far less common over time than with a push fit for the reason I outlined. I assume a push fit system would also have to be drained if a joint started leaking.
