after adding mysolar system, now when i turn off the solar panels they drain down using the VRV letting air into the system which from what i read is normal. now my chlorinator used to stay full when pump was off but now with the air in the system the chlorinator drains also. when the system turns on automaticly in the AM the chlorinator doesnt fill back up unless i prime it each day. has anyone seen this? or know a fix?

Hi, have you got a working non return valve to prevent the drain down of the leg?
VRV?

Vacuum relief valve (vrv) allows air in panels so they drain. I also do have 2 check valves (non return lines) on the system.

OK, maybe you could sketch a schematic for us to look at?

Excellant diagram very clear
Does your pump lose prime if so the check valve after the filter is faulty
If it doesn't isn't the pump powerful enough to force the water through the chlorinator
I suppose that when you re prime it you open the bypass valve and close the solar isolation valves to force it through the chlorinator

Not sure of your exact pipe layout (physical) is there a loop on the exit leg of the solar? if your pad is above the water then it will drain out without a loop to contain some water, possibly. any photos of you pipework available?
