In the 6 years I have been doing inspections this is only the third on demand water heater I have come across.
I noticed a couple things wrong with the TPR valve discharge piping. I noticed there is a small leak at one of the connections, there are 4 elbows in the discharge pipe, and TPR valve drain should be independent of any other plumbing…
I thought I would share to see if anyone could explain to me what the braded line was for that is tied into the TPR valve discharge piping?
Is this a different style of TPR valve?
