I am just finishing up replacing my pool liner this fall. I admit I am a little slow. I was double checking the skimmer screws before I cut the hole and noticed one screw would not tighten like all the others. Since I replaced the liner with my wife, I recalled a rust hole on the wall around the skimmer in that area. I initially thought it was caused by the gaskets failing overtime. Now I believe the installer many moons ago stripped it on installation of pool and never addressed it. It is the lower left corner screw.
I used the rubber gaskets for the Hayward wide mouth skimmer when I replaced it, hopeful that is better than original gaskets. I have called around to pool builders and only one offered advice on fixing/repairing it. He said to put a larger stainless steel screw in it. I am concerned that would break the plastic.
I called Hayward, they told me to put lots of silicon in the hole and put screw back in.
I did find a post on the forum that talked about using Anderson flexible sealer. I have ordered some of this material. The water is just below the skimmer.
Does anyone have any experience or advice for this issue? Thanks
