Hello, just bought a home and am a new pool owner for a whopping 10 days. Have noticed something that didn't sit well with me and am seeking advise.
I have an IG ~10,000gal pool w/ two intakes, one being the skimmer, the other being an intake dedicated to the Hayward (its older, looks like the "poolvac classic" though). The skimmer & poolvac line come together to a Hayward valve which allows me to select what enters the pump.
When the valve is open to just the poolvac, the pump gets significantly louder & PSI drops on the filter. There is also a significant build up on the air (when I turn the pressure release on top it always bleeds air for a while, though air isn't making it to the returns to the pool). When I turn the valve toward just the skimmer (either partially or completely) the "rocks flowing" sound goes down & the sound of flow in the pipes can be heard. When this is the case, the poolvac hardly moves (partially open) or obviously not all all if it is skimmer-only.
The pool is about 12 years old, taken care of solely by the owners poolguy... Her only advice was leaving it entirely on the poolvac side and never skimming. She was a very "if it ain't broke don't fix it" type & had original filters in the 12 year old cartridge filter as well. What needs fixing? I will pull out the cleaner tomorrow and see if I can get a serial# to see how old the thing is, also inspect the tubing again.
Thank you so much for your help... I am at much of a loss here.
