Leaking push fit joint

[dancinplumba]

I like to give mine a good hard tug to satisfy myself.

Oooo Don't we all

OP you now say you have put a new hep insert and a speedfit reducer, you have made your situation worse by mixing manufacturers.
The hep fittings/inserts have the "rumble strip" which allows you to feel that the fitting is fully inserted. I suspect you had not fully inserted the fitting the first time, it is actually quite a firm pressure required to do so, a little smear of silicone grease aids insertion and lubricates the o-ring making dismantling easier if needed. I know you'll say you did it properly, but I bet you didn't!

As the fitting didn’t come off the pipe, then pressure testing would only have improved the chances of finding if the joint could leak.
I hate plastic push fit but where I have to work with it, or for example - on push fit pump flexi hoses, I use smear of silicone grease.
That first contact with O ring is very likely to damage it.
Copper and soldered joints any day

Well I think this is the point you’ve not installed to MIs lots of plastic manufacturers ask that you input an excessive pressure (depending on brand) to ensure that metal grips bite into the pipe

Would you pressure test if you fitted just one fitting ?

He didn’t say he’d fitted just one it said it came up in plastic pipe so I assumed it was the end of a run. Maybe I’m wrong?!?

You guessed right, I did insert it properly and felt the rumble. I believe that provided you put the correct inserts in the pipe for the pipe manufacturer you can then put a different manufacturers fitting on as all the pipes have the same outside diameter. Because the original was a Hepworth pipe I put a Hep2O fitting on but lost confidence when it leaked hence the change to Speedfit which I have always liked and I also like the added security of tightening them after insertion.

This is mental!
When you think of it, - after installing just one or two plastic fittings, you then are supposed to pressurise the pipework to a high pressure for a time period.

So much for plastic push fit ‘speed.’

Copper pipe, soldered joints done, water on, quick confirmation no leaks and I am in the van

When I took the joint apart it was fully inserted and I had given it a good tug on assembly so that wasn't the problem. It had not come apart at all but was just leaking.

Copper, as Best said, the only way to be sure.

I know where you're coming from but the existing pipe was 22mm plastic so just a few fittings to the flexi from the bath taps.
