About Bonaire & Celair evaporative cooler drain valves
A faulty drain valve can leave the tank draining when it shouldn't (so the cooler never fills), or never draining (so scale builds up quickly). Check which system your cooler uses before ordering; H2O Optimiser upgrade kits are also available for some models.
For seal replacement on the Aquamiser, see the Aquamiser valve seal. For simpler dump valves see Bonaire dump valves. Contact us with your model number if you need help.
