First time poster here and very excited to find this forum.
Pool was running great overnight with suction cleaner and woke up to find cleaner not running with bubbles all in pool! (Air coming out of return line every 2 or 3 second)
The strainer basket now has air in it when the valve is fully open, but when i close it a bit the pump primes fine but when I plug in the suction cleaner it loses prime immediately and almost becomes empty of water with zero pressure.
I have a brand new strainer gasket as well as top and have checked the pumps plug and all look fine. Also there are no visible leaks anywhere when i try the towel test as well as water hose test?
I am afraid I have a suction leak under the 3 feet of concrete by the skimmer...........Any advice would be great!
