I am installing a Waterway Large Mouth Skimmer in a new IGV pool. Should I use a silcone sealer on the gaskets that touch the metal walls? What is the best way to install a skimmer? Are there any tricks or tips that the installation manual does not disclose? Or should I just follow the installation manual completely.

Any suggestions are welcome!

This may differ from other suggestions and if it does, follow the folks advice that work on pools all the time.

I'd use a thin bead of silicone sealant on each sealing surface if it were mine. The thing about silicone sealant is that's it does a really good job of sealing and it's relatively easy to remove if you ever need to. Beyond that, follow the mfg's recommendations as closely as possible.

Thanks! I'll get some silicone sealer...
