Hello. Does anyone know what this tube is for, is it a pressure relief tube?
Thanks Damon Newsome
Condensate line from the WH’s heatpump. You should note on the report the type of WH it is 
Where did the top portion of the blue line connected to the tee go?
The top portion hung freely. Also will do.
Thanks Simon!!!
I don’t see a drain line for the TPV.
The manufacturer model info is printed right there on the product. I recommend you take a few minutes, go online and read the installation requirements for that appliance.
One is not installed.
No shut off.
No approval sicker for the replacement.
Hot/cold water bond?
