on the suction side...
Pump - TWV (three way valve (to pump, from spa floor, from pool skimmers). A couple of 90o elbows that seem very air-tight, and then 2" pipe into the ground.
TWV Direction from Spa floor. Zero air coming in from that direction - pump basket removes all air.
TWV Direction from Pool Skimmers (skimmers have plenty of water) - pump basket collects air. Not enough to break suction on the pump, but there's still quite a bit of air coming into the basket and making it back to the return jets.
The only place I can imagine air coming in would be a leak somewhere in the 2" PVC, but the pool doesn't lose water when the pump is off, and there's no dirt getting sucked into the filter (just cleaned the filter a few days ago - lots of dead algae, but no dirt...).
(edit - oh yeah, and when I have the vacuum hose plugged into one of the skimmers (and plug the other skimmer w/a tennis ball), so much air gets into the pump, vacuuming becomes impossible)
(another edit - brand new o-ring on the pump lid...)
Ideas? Things I should be looking for?
Thanks,
- Jeff
