Due to all the rain we have had this summer in New England, our in-ground gunnite pool is at or above it's maximum normal water level. Since I don't know what the weather will do in the future however, I'm reluctant to pump any water out of the pool. I don't know of any serious problems that being over full should cause, and I would just as soon not get rid of the water I have now, just to need to put it back later as metered town water...
However I am having a problem with the wier gate on our skimmer - it keeps getting stuck in the closed position, usually when somebody has been using the pool and thus generating wave action to push the gate back and forth... When this happens it restricts the flow into the skimmer enough that the skimmer basket empties out most of the way and the pump starts sucking air as well as water.
As best I can tell, the problem is that the 20+ year old skimmer gate has worn it's pivots to the point where it is hitting on the top edge of the skimmer and is getting hung up. My initial thought for a fix is to trim a quarter inch or so off the top edge of the gate so that it can't hit the top of the skimmer any longer... Does anyone know of a reason NOT to do this, or have a different suggestion for a fix?
