I learned last summer that the cartridge filter for my Intex pool wasn't very effective...so I saved for a 14inch Hayward Sand filter. The Hayward hoses are 1 1/2 inches and the wall fitting is 1 1/4 inch. I have an easy set pool 15' X 48". I can't find any adapters and I am not sure what to do...all pool stores look at me like I am crazy.... My pump is 40 GPM so it is strong just afraid if I use 1 1/4 inch hose it won't be able to accommodate the strong flow....PLEASE ANY HELP IS APPRECIATED! My kids are desperate to swim in this AZ heat but I don't want to fill it up until I have the filter system figured out!!
