Fresh Water System Start-Up Procedure

  • Close all taps including your drain-down valve
  • Fill fresh water tank with tap water. If you are refilling after the winter or other prolonged lay-up add a disinfection agent to the water in accordance with the manufacturer’s instructions
  • Ensure your 12V electrical system and pump isolation switches are on
  • Fully open the hot water tap that is furthest away from the water heater
  • Wait for the water to run steadily from the tap. It may take some time as the water heater tank needs to fill up first
  • When even flow is achieved open up the next hot water tap closer to the water heater until smooth flow is achieved and repeat this for any further hot water taps
  • Close all hot water taps and repeat the procedure with the cold water taps, starting with the one located furthest from the hot water tank
  • With a smooth flow achieved, turn off cold water taps
  • Check for leaks including to the underside of taps
  • If you have filled with a disinfection agent, allow the solution to stand in the system for the recommended time and then drain down. Purge the system by running two or three tanks of fresh water through the system with all taps open at the midway point.
