We anticipate the requirement of a couple of extra wall suctions on a vinyl pool that we are building that has 2 waterfalls. The 2 skimmers on the pool will provide the water for the pool and spa returns.
(We removed the bottom drains from all of our pool designs for safety about 10 years ago......)

Does anyone know of a decent wall suction 2" that will work on a vinyl liner pool with VGB safety in mind......?

Should we tee the wall suctions to the skimmers to add an extra degree of safety?
