AUTOMATIC ABOVE GROUND POOL FILLER...got tired of overfilling my pool. This clamps on the edge of the pool using a toilet float, my pool has a 16mm x 16mm metal lip hidden by plastic "beauty" pieces. This pool filler sits nicely under the beauty panel top plates.
I used galvanized pipe for the time being but i need / recommend to get PVC, holes for pipe and and float is 23.4 mm (3/4" EMT). Once you figure out the water level you want you can cut your PVC pipe even with the top bracket.... which i haven't even done yet. I also didn't use the mid_clamp, it is unknown yet if it is really needed, but i made it anyways. Over all cost of this project might set you back $20 USD as of August 2018.
screw holes are 4mm and i used the screw itself to self thread, the "auto_fill_top_V3" is specific to my pool that has a 16 x 16 mm edge. Use a thick shell setting in case you need to drill out the holes for your bolts or pipe i used 1.6mm shell.
P.S. The pictures are of an older clamp i made that wasn't quit strong enough, a improved stronger and more compact top clamp is posted in the files. Also you are on your own with the plumbing since it can be done several ways.
Maybe, just maybe someone has this same pool frame and can use this auto filler...
