EBD4A 4" Heavy Duty Bottom Drain with Air Diffuser


Many pond builders have found that adding a bottom drain helps keep a pond cleaner. Fish waste and other muck that accumulates on a pond bottom can be easily removed by a bottom drain. Ponds that are over 2′ deep can become stagnant without a bottom drain.
