I am building a solar heating system on my roof for my IGP ~18,000 G. Because the pool is the type with inground jets (sprinkler type) cleaners there is no sweep machine or pump outlet into the pool from the main filter pump. I cannot return the solar heated water to the same line because of the pressure is the same. It won't work. So........I have to run the solar heated water into a "feature" pump output line, (after the pump) this is NOT the filtered line from where the water is diverted to the solar panels.
Here's my questions;
I know I need a one way valve after the diverter valve on the solar panel supply side. I'd like to put a one way valve on the output side of the panels just before the "T" at the "feature" pump's output to pool side. The panel manufacturer says NOT to have 2 one way (check) valves in the system or it will void the warranty.
Any ideas why?
I do not want the "feature" pump to reverse pressurize the panels when it kicks on. I have no other means to return the panel flow to the pool. Dual end pressurizing would be disastrous! What am I missing with the dual one way valves?
Panels are 4x12 Swim Master Plus (5)
Thank you for your help,
Ron
