I'm really new at this also, but I have lots of questions.....most of which I can find the answers to on the forum.
Does anyone have bubbles (air) come in the line when you switch from high to low on the pump?
We have an 18x38 Doughboy with a .5/1.0 Hayward pump. (Is this a big enough pump for a pool this size??) When I switch from high to low on the pump, air bubbles come in the pool for a few minutes, then go away and filters normal.
Any ideas?
Thanks,
