I moved into my house a few years ago and have been having problems with my pool pump. I have been getting air bubbles pumped into the pool, as well as the pump leaking in various places. I have taken the pump apart and replaced all the seals twice. This usually helps for a little while and then it goes back to air bubbles. I replaced the above ground suction lines and again that helped a little.
After doing some more research, I think the issue is that I have a pool pump that is too big.
I have the Hayward SP2615X20 - 2.0 HP Super Pump
Pool Size - In-Ground, 10,000 Gallons
Pool Filter - Hayward Sand S244SV
Suction - There are 2 lines that meet at the Jandy, the Skimmer and the vacuum line. I believe the main drain runs through the skimmer basket (still can't figure this out). The skimmer is approx 22' of pipe from the pump and the vacuum is 27'. (This assumes they ran the pvc in the shortest / logical route.)
Suction PVC - 2"
Filter to pool - 2" PVC + 1" branch for small "water feature" sprayer
Outlets - 2 water jets back into pool.
My math is telling me I should have a 3/4 HP Pump. Such as the Hayward SP2605X7.
I have no idea why they installed such a large pump.
Please let me know if I've made any errors in my calculations. Thanks.
