I can believe that you can't replace the part. I found the same problem with many pool products. I worked for a pool and spa store many years ago. We stocked and sold all kinds of parts for skimmers, pumps, filters,ladders,etc. etc. I too have had problems finding parts. I believe the name of the game is why sell a $1.00 oring or gasket when you can sell a $20.00 lid. I use to buy a 50 cent oring for my 1 1/2 inch winterizing plug but now I have to buy the whole plug. I am not sure if this is a difference in the states or what the store want to bother with. I use to live in PA , past 8 yrs been in FL.
