Leaking push fit joint

[Vicdiy]

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!

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

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

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.

I was under the impression that you pressure test on full installs and small use is not necessarily done with pressure test.

I understand. Not a lot you can do other than work with what is already there

I bet the pipe is scored, how else could it dribble unless the o ring is damaged.

Ever seen at merchants the straight lengths of plastic pipes being dragged by staff or plumbers along the ground?

They are part of the problem plastic fittings out the bags strewn over the shelves, pipe dumped on ghe floor in merchants

I agree but I wonder why it was over a month before it dribbled?

Hot was it?

Yes it was the hot but the bath had not been run for over a week before it leaked
