Hep2o pushfit grey, Grab Ring Failure ?

[JonInvestigations]

I had a leak coming out from this reducing tee just after a month after installation.

I think it’s an old Hep2O tee.
I took it apart and found that the grab ring had scratch the PEX pipe.

Making me think the pipe had move out of its place.
Has anyone else have the same problem and any idea how this could happen ?

What brand is the pipe? Hep20 is grey

I ask, as the theory is... you use the pipe brands own inserts and that pipe may not use that insert

That looks like a HEP ftg on JG pipe.
In my experience its pressure fluctuations that have caused that hi lo hi lo. Was it on the hot side of an UVC?

Hep20 is white now

I don’t know, I haven’t used hep20 in about 10 years, it could be pink for me

John guest for me, if I need to use plastic.

Also... the fitting isn’t white, so maybe a case of cross contamination

The grab ring has scratched the pipe but not where the O ring sits. Looking at the marks it looks like the scratches have occurred while whoever fitted it, was pushing and twisting. When was it installed? If it's a month ago then chances are that has been laying around for a while before been used as hep changed their fittings years ago.

Or severe water hammer

Its wrong , the seal goes into the fitting first not the grab ring

That made me stop and think and I haven't got one to check Jon. However, our very own 'old bugger' looks to be 100% correct.

His back's beggered, but his brain still works - bless him

All hail Emperor Jon

Yep, you da man John. I never picked up on it.... embarrassingly!

Agree, very embarrassing. Just shows though: look for the bleedin' obvious FIRST.
(I'm trying desperately to justify my utter incompetence as I look into the mirror...)

Also, it may have wrong pipe/ insert combo as well
