Hi,

We have an in ground pool. For the last year I've noticed that that there's nothing in the skimmer baskets...and I used to see the water swirl when looking down at the skimmer basket. If I lift the skimmer basket and put my hand over the ingress hole I can feel suction but I'm guessing it's not as string as it once was. Also, there is a lever at the pump for main drain versus skimmer and I've moved that towards skimmer.

tia,
