Bryan Posted April 8, 2016 Report Share Posted April 8, 2016 Good afternoon. During a recent inspection of a small apartment complex the PEX water lines leaving the water heater were discolored (see photo). This was primarily on the hot side; however, the return loop line was also discolored. The installer did use copper for the connections to the water heater up to about 18", which is supposed to be the minimum. Any thoughts? FYI: the hot water was around 125 degrees.

gtblum Posted April 8, 2016 Report Share Posted April 8, 2016 Any idea whose PEX? One thing for sure. It's another perfect example of an installer without a clue about PEX. Look at all of those joints. Quote Link to comment Share on other sites More sharing options...

LeePlace Posted April 9, 2016 Report Share Posted April 9, 2016 Did the discoloring wipe off? There is evidence of some sort of liquid product that was applied to a area of the ceiling and on top of the vent pipe. The pipe that does not show any signs of discoloration could have been replaced. Quote Link to comment Share on other sites More sharing options...
