Bottom Drain, LWS Ultimate Bottom Drain

The "Ultimate Bottom Drain" is the first bottom drain to have internally threaded fittings for sealing or pressure testing during construction! Both the 4" outlet and the 1.5" dome support post are schedule 80. The 9" air diffuser has one of the lowest back pressure readings of any on the market at less than .3psi at 60 lpm and is recessed into the dome as an integral part of the cover itself. This eliminates the air diffuser as a protrusion into the pond above the dome. The 4" outlet exits at a 22.5 degree angle to eliminate multiple fittings when plumbing below a concrete floor. One additional 22.5 degree street fitting or a short section of pipe and a standard 22.5 degree fitting is all that's necessary to connect to the outlet piping. The mechanical clamp ring is recessed into the flange for a smooth flow of water and debris into the drain from the pond floor without the obstruction of the ring's edge.
