POOL PUMP ISSUES/BUBBLES

[mpoland33]

I recently bought a dual speed pump, 1 HP for a 18' round above ground...to work with a Hayward Perplex DE filter

My problem is....

Originally when I bought it the high speed worked fantastic and as quite honestly impressive. I vacuumed with it...perfection.

I started er' up last night to vacuum and low puts out a trickle (out of the return) and high works about as well as low used to. Also, air bubbles spit out of the return...AND the pumped works slow for 20-30 seconds spitting out air bubbles and then it's like a toilet bowl flush where everything rushes through and the return works/skimmer works completely normal. It works normal for maybe 5 seconds and back to low return water and low suckage.

Any ideas?!?!

Have you backwashed the filter?

Maybe the lid on the pump is letting in air

Check your skimmer weir door isn't jammed shut and you have sufficient water in the pool 1/2 to 2/3 up the opening
