Greetings all!
I have a spa which is surrounded by a concrete surround. Water was seeping out from a seam in the concrete and, after some detective work, it seems the culprit is a bad seam in the skimmer: The plastic skimmer connects with a plastic riser at an angle, and the plastic-to-plastic join must be poor, and when the water rises to a certain level, water seeps into the concrete, and then is slowly released by the concrete. Since we lowered the spa water below that join, the seeping has stopped.
So my question is what product is best for sealing a plastic-to-plastic join, which will usually be under water that is hot, and is chlorinated? Do I want a flexible seal, or a non-flexible seal? There is some product I saw at our pool supply store called "A+B Epoxy Putty."
Any advice at all on this matter is greatly appreciated!
Chuck
