React Solar Pump Spare Foot Valve

Every React Pump owner should have a spare foot valve on the shelf (other than those who have a gravity-fed supply)

This part must be replaced each year and kept in perfect working order. Once the foot valve starts to leak, the Triplex may be unable to clear air in the system and hence not be able draw water into the pump body on sunrise. 

 It you run your pump air-locked (without water) you will likely damage the wet side pistons seals (water is needed for cooling and lubrication). These seals will then leak once you fix the faulty foot valve.
