Are those connections on heating, or tank fed supplies, or pump fed supplies, or mains fed supplies?Should I go back to the pipes and fit sleeves tobe on the safe side?
The cold is mains fed, the hot is from a sealed combi boiler.
No, because the grab ring/wedge would then be too far from the end of the pipe. With Hep2o this is a minor problem, but with Polypipe fittings the steel ring is a royal pain in the ar*e to move without destroying it and/or scoring the pipe.Is it just a case of pushing sleeves inside the plastic pipes & refitting the push fit connectors?
I could probably lose an inch on the pipes & slide the grab ring off from the oher side. I didn't realise that you can simply push the connectors back on over the sleeves though?
Yes, it would be....I had visions of having to push fit copper pipes to the plastic ones & then using compression joints to join the chrome pipes to the copper ones, which would be a messy install for all pipes.
You can use brass compression fittings on plastic pipe, but using the sleeves is [even more] imperative, and don't murder them when tightening up.
I'll be extra carefull when I tighten them up so as not to crush the plastic.
Is it worth using plastic comression couplers to be extra safe. I have these in the form of a tap feeding my shower, but could probably track down some plastic compression couplers if they are any better?
