I have a pool with solar panels on the roof of a three storey house and a variable speed pump.
Why is there a need to drain the solar panels through the vaccuum relief valve?
It seems to me that if you primed the panels at the beginning of the season, the pump would be able to run a lot slower (because it wouldn't need to maintain the head), and it would be more efficient.
But there's probably something I'm not thinking of (so I thought I'd ask, before I tried blocking them.
Thanks!
