Clean as they are, there is not one drop of primer on hundreds of large joints in the building. That is 2 step glue (orange). Just becuase it looks pretty doesn't make it good work.

Well, I will say that those are some clean glue joints there. Unlikely of a rookie or UNhandyman.

no means of expansion although hangers are non-clamping. No loops. etc. I'll post some more pics tonight of corrosive pipes ran in regular pvc and copper, orange glued flowguard no primer, compression fittings used on med gas piping (nitrogen, comp air, vacuum, co2) and more.

Those RO lines look like Harvel LXT. We use a one step cement on LXT. When it's done right you can barely tell it's been glued.

yep them's pretty. just found no backflow prevention on water softener caused brine solution to backfeed into boiler somehow and cause serious issues. Installers explanation "the system's under pressure water cant flow backwards....." he should of added "unless the booster pumps power fails and o'yea the water softener is on the 4th floor above and after boiler tie in.... glad potable water system has its own backflow prevention devices or else my break water would of been a little salty.

Im with UA maybe they used clear primer. The orange glue is CPVC glue, although I am not sure if it suppose to be used with Corzan pipe. That is the same pipe I had problems with underground, but it was used for heating water on a hydronic system.

Maybe it these gettin' older eyes ,,, Now I'm not say ing that I don't clear prime ,, I DO !!

If that is YELLOW glue and not Orange ,,, then the specs call it a "one step " and it is the only glue ( acording to manf. specs ) that doesn't require cleaner/primer

DON'T JUMP IN MY A *** ,,,,, Just reporting ,
