Hi There-
I am installing a new heat pump for my pool and have a question with the plumbing. I have an old gas heater that I would like to keep for standby that used 1" copper plumbing. Does anyone know how I can tap into the copper output line with the 1-1/2" PCV output line from the heat pump? I assume that I will also need to use some sort of 3-way valve as well.
TIA,
Civil Bear
