Evolution Aqua 4" Bottom Drain with Air Diffuser

Evolution Aqua


The EVO 4" Aerated Bottom Drain is made of heavy duty Schedule 80 PVC. It features both a 4" horizontal pipe fitting and a 1" side-mounted aeration pipe fitting to make aeration simpler. The center stand pipe can be adjusted, threading to the underside of the aeration plate and gluing to the bottom of the drain base. Includes stainless steel screws, liner ring and aeration disc with plate.

We recommend between 30 and 100 liters of air per minute with this aerated bottom drain.
