Airmax PondAir Air Line Check Valve ARM490314

ARM490314: Check Valve

Water tends to climb aeration airlines when your aeration pump is powered down. Airflow check valves allow oxygen to travel outwards from the aeration pump while preventing water from traveling into the lines when not in use to prevent potential water damage to your aeration unit. (Replacement Valves for the PondAir 2 & 4 Areator Units)
