The 4″x 2″ Bottom Drain and Dome are designed to give a high efficiency low maintenance system when constructing a pond, as it draws debris and solids from the pond floor. The 56mm outlet on the 4″ x 2″ Bottom Drain gives a high flow of water which gives a good “draw” removing debris from across the bottom of the pond
