Probably knock off fittings or similar and it's likely they may not supply direct burial rated ones to be price competitive. DB is gonna have a lot more pressures and movement from the outside. Even top side would see a lot of potential pipe movement.

They get condensation so it is not apparent that it was happing. One fitting had drip when there was no condensation.

I got the razor blade and found one leak. Then a cut open all fitting like this one and everyone had a drip.

I replaced all of them with crimp fittings. I just checked again after A few hours and it still had good pressure.
I will check tomorrow and some going forward to make sure I have good pressure.



These worked for two years not sure why they just are not working anymore but they are all gone now.

All the fittings are in my crawl space. It just looks bad as it was wrapped in insulation and leaking.
I think they were knock offs. I am glad they are gone.

I have no connections at all under ground. All loops terminate at the manifold in the crawl space.



These smaller push Nibco fittings are all doing fine. It was just the 1" fittings that all went bad. These smaller fittings seem much higher quality.

Loop pressure has held @35 psi for almost a week now. This is good news.
It is back to just working again.
