Here is my problem: When my pool is running from the skimmer, the pump seems to be running fine; a few air bubbles at the pump lid. The pressure holds pretty steady at 12-13 P.S.I. and the suction feels like it's normal. When I attach the Hayward Pool Vac to the skimmer inlet the pump just pulsates/chugs and the pressure varies wildly from 2-5 P.S.I. and the Vac is barely moving.
Things I've done so far:
1. Took the Sta-Rite 1 hp motor off, checked the impeller. Looks fine.
2. Lube the Pump lid O-ring. (Could be an invisible crack on lid)
3. Snaked the inlet pipe for debris. Seems clear.
4. Closed off the skimmer inlet; filled pump inlet with water. No air bubbles observed and pump filled with water so hopefully the inlet pipe isn't leaking.
(Note: my main drain is blocked and inoperable in order for the pool vac to work properly-old style pool with one diverter valve in the skimmer).
5. Checked the Pool Vac/hoses- seem fine, no obstructions.
I'm kind of at a loss as to what the problem is. Is it the pump inlet pipe/fittings that have a small leak causing this. That's my only guess right now.
Any help would be appreciated.
Thanks
