Non Return Valves (check valves) 4mm
Pack of 3

These simply fit in line and prevent water from the system siphoning back into the Air Pumps if the power fails or when maintaining the system and the power is switched off.
Non Return Valves (check valves) are very important if you cannot mount your air pump above the water level in your system. Remember accidents can and do happen!
