Saxon Hot Systems

Fill Saxon hot water tank up
  • If you have a Saxon hot water system you may have to top up the tank. 
  • Once every six months the pressure relief valve must be checked by the owner. To top up the tank and check the valve, lift the valve lever against the spring pressure until water flows from the overflow pipe. When water flows from the overflow, restore the lever to its original position. (Do not let the lever snap back, as this may damage the valve seat). As cold water is introduced into the tank, it will expand and continue to flow for some time. It is good idea to do this check whenever you receive your electricity bill. If water does not flow freely – Call K-Oz Plumbing
