We are just putting up Intex ultra frame 16X32. I am wanting to hardplumb as we set it up. It doesn't come with a true skimmer, having only a large return and thru wall strainer. We are putting a Hayward skimmer and adding 2 regular Hayward eyeball return jets. I would like to replace both the original Intex thru wall parts if possible also with 2 more Hayward eyeball jets, using the strainer one to become a regular adapter for a suction side pool sweep. That would give us a total of 3 actual jets, one real skimmer, and one suction pool sweep. (We come from the inground pool world and are used to letting the Polaris 360 roam the pool permanently, except when too many people playing--can't use that one in vinyl pool so will get Hayward bug or something.) My real question is that the 2 Intex holes are 1/4 inch bigger than the standard Hayward thru wall fittings. The Hayward gaskets are plenty large enough to cover, but not sure it will seal well. Will it work--should I make a larger patch glued over the holes first, then install--I don't know. Help Please! Here's a link to another site that has pic of intex parts if interested. I'm writing this at my office so can't take and Photobucket actual pics right now.
