Hi,
I will be instaiing my 5 new solar panels this weekend on the roof of my deck (10' above filter level). the questions i have are:
the kit came with 2 check valves but I only thought i needed one valve on the line from the DE filter to the panels to eliminate back-pressure when the pump turns off each day. Do i need to put one on the return line as well?
Also, I'm installing a relief valve that's supposed to allow the panels to drain when the pump turns off but I can't figure out where the water will drain to if the check valve will close not allowing the water to drain below the valve. i was planning on installing the valve on the vertical run halfway up the wall of the house to the roof so there will only be about 5' of pipe between the valve & the bottom of the panels which can't possibly hold the water from one panel, let alone 5 of them.
What am i missing?? thanks
