Low skimmer suction
We have very low suction in both skimmers of our in-ground pool. It started about a week and a half ago. We have backwashed several times, run cleaner solution through the filter and today changed the sand. It pulls debris into the skimmer, but not down into the baskets. We also checked the pump and the impeller seems to be fine. Any other suggestions?

What's your returns like?
Floating debris won't be sucked down, if it did then you would pull air into the suction line and stop the suction

It should go into the basket and not float on top. We've had the pool for 40 years and this has never happened. The debris gets pulled into the skimmer area then just floats and prevents other debris from entering. Our pool surface is a mess.

Re: Low skimmer suction
You don't mention your return flows as that will determine whether you have sufficient suction

Re: Low skimmer suction
If the return flow seems to be fine then the suction should be OK
What's it like on filter bypass / recirculate

My husband just tried that and there was no change. We're at a loss, we can't even use the pool because there is so much debris on the surface.

Re: Low skimmer suction
Right, then the only other thing could be a restriction in the suction pipe or the pump is blocked
First of all dismantel the pump and check the impellor for a blockage
To use the pool use a net to clear the debris off as a temporary solution

Re: Low skimmer suction
My husband didn't take it apart but said he was able to reach in and spin the impellor. Is there something he should look for that he needs to take it apart to find?

He just took the pump apart and said that everything is fine there.

Re: Low skimmer suction
You need to disassemble the pump to check that there isn't any blockage in the impellor
There should be 4 or 5 bolts holding it together

Re: Low skimmer suction
He did that, there’s no blockage
