A few things I have learn in applying some of the ideas in this thread.
1. The electrical conduit adapeter works great.
2. it is easier to just switch to 1 1/2 in jets, - I did mine with the pool full, just using freezer bags to cover the opening as I slid out the old & in with the new 1 1/2 inch jet into the slightly larger Intex holes. I did drop the water level to add a new jet near the up wind side of the pool & just followed the hayward instructions. I dumped the Intx valves after one broke after winter storage, it is nice to have just standard 1 1/2" so repalcements can be found anywhere.
3. the Hayward skimmer does not seem to skim as well as the intex floating skimmer. Last night I hooked up the Intex skimmer to the hayward inwall skimmer with the hayward cleaning attachment, I might just use tat cofiguration & remove the intex while swimming.
3a. I used the hayward frame to mark the holes for the inwall skimmer, I think I could be 1/4 inch higher if I had used the gasket for marking. I had to drop the pool level 2 to 3 inches below normal level to have the hayward work at all. It just seems the junk, leaves et all just float around in the top of the hayward skimmer. I have the larger 2650 Intex pump running thru a 4 X 20 solar heater, that seems to be plenty for volume. All plumbed with X 3 insolated 2" piping -(2 1/8" foam, 6" X 2 each roof eve tape, covered with 4" drain pipe, and wraped in plastic & buried 1 foot deep - with a french drain under the piping.)
3b. If I had bigger ____, I would install the skimmer up in the white seam material sanding down the rib area around the gasket to get the Hayward higher in the pool. I have a 12' X 24' Ultra Farme. 52".
4. I used a hose picked up at "Tractor Supply" 20 feet for 25 & a combination of both PVC & hose - I think there needs to be some flex in the system too prvent brakage with the kids hanging off of things.
