Hi all (the fun never ends!)
This year has been really hot and I've noticed that I've had to refill more than usual. I don't suspect a leak as some days there is no level change while others an inch or more of loss between checks (24-48 hrs). Pump runs on a 24hr/day (on a timer for different speeds throughout the day) but will periodically re-prime between settings/timers.
What I've found is over the 10 years of the pool (I've owned it for 4), the optimal water level has etched itself on the skimmer face plate (white line whereas rest has turned yellow). My issue is if the water level drops about 1.25-2" from that optimal level, when my pump primes, it sucks the skimmer dry. Is this a normal level of water level tolerance? The line is about 3/4 up the face plate (if that helps with an idea of how full it needs to be).
In my googling, I found what I think to be my actual skimmer (Hayward SP1080 - https://www.hayward-pool.ca/pdf/manu...P1080-1082.pdf). I noticed it talks about only having 1 suction line while the other 'hole' is used for a 'equalizer line'. Mine was plumbed with both as suction lines. My neighbour's is the same way (same pool builder).
Could the whole issue be that I have 2 1.5" suction lines from my skimmer? Do I just close 1 of my valves at the pump and plug the hole in the skimmer?
