I know what you mean.I don't want to correct you or whoever did this, but threaded and pro press are not code underground. Just some food for thought.
Yes. Where the dresser coupling was the 2” fail site. We just had the objective to get the 6” main pressurized which was across the drive. The 2”ended up being full of holes so we dug down to the main and installed a ball valve on the 6x2 tee.ProPress is allowed underground.
there was, at first, an advisory reco. To wrap joints with silicone tape, but now allowed underground all over Calif where soils are decent without wrap,, even under slabs.
I’d assume that the dresser coupling is temporary. We’d never have anything like that be permanent.
