1. Do not use anti-vortex covers, use only Anti-Entrapment covers. Anti-vortex covers present a potential hazard for Hair Entanglement, and the smaller open area of some anti-vortex cover designs results in higher hold down forces (>15 lbs force) should one of the dual drains be blocked by a bather. 2. Dual drains should only be constructed with sumps having 2" connections or larger. Sumps with less than 2" connections (1-1/2" or less) result in higher hold down forces (>15 lbs force) should one of the dual drains be blocked by a bather. 3. Dual drain connector piping (sump to connector tee) should be 2-1/2" diameter or larger to minimize hold down forces (<15 lbs force) should one of the dual drains be blocked by a bather. 4. Dual drain separation distances should be minimum 3 feet and should be kept less than 6 feet. Greater separation distances must be compensated for through the use of larger diameter connector piping in order to minimize hold down forces (<15 lbs force) should one of the dual drains be blocked by a bather.
