In one of the pools, the skimmer / main drain diverter (as shown at the visual encyclopedia from the PS) pool-school/visual_encyclopedia, seems to have trouble working as it should.
Looks like the "floating" device from the skimmer sinks and gets stuck once it is placed in the skimmer cylinder therefore the "suction" from the skimmer is cut and the debris is not pulled to the skimmer and stays in the pool area. I though could be having a lot of suction power, but this happens with or without suction.
Do you know if there is a way of making this stop happening? Any maintenance? lubrication? exchange? has to be made?
Thanks as always!
