Most of us tend to ignore our hot water service until it’s too late. Rheem has some key tips to help you identify whether your hot water system is on the way out – or might need some attention. If you have the system checked on a regular basis, you can extend its serviceable- life; improve efficiency; ensure your water heater is operating and performing as designed; and highlight any repairs or preventative-maintenance that should be done.

Signs your hot water system might need attention:

  • Is the water coming from the tap rusty or brown in colour?
  • Is the water muddy or does it have sediment in it?
  • Is the hot water system making strange sounds? Some noise from the water heating up is normal, but if you notice cracking or popping noises these should be checked.
  • Has the pilot light gone out? Does this happen often?
  • Does the hot water have a strange smell or metallic taste?
  • Are you getting less hot water?
  • Is water leaking out of the system?
  • Do you often experience fluctuations in temperature?
  • Does the water pressure or flow rate vary?
  • Are you running out of hot water?

Rheem Service undertakes regular checks of domestic Rheem hot water systems. It offers a range of services including six-monthly minor maintenance, an annual service and a major five year service. The major service includes replacing the system’s sacrificial anode, temperature and pressure relief valves; checking correct operation of the gas, electric or solar control; and checking solar heat transfer fluid [for solar hot water systems]. Rheem recommends having domestic hot water systems checked around every three years for gas and electric systems, bi-annually for solar systems, or whenever you feel something has changed or you have noticed any warning signs.

The most common problems discovered during service checks are:

  • Pilot light outages [which results in leaking valves].
  • Leaking valves.
  • Installation issues.
  • Temperature settings set too high [which increases running costs].
  • Excessive water pressure [this adds stress on the cylinder, thus reducing the life of the system].
  • Incorrect gas pressure settings.
  • Relief valves which are stuck and then leak constantly due to householders not operating the valves every six months in accordance with manufacturers’ instructions.
  • Blocked strainers, causing flow rate issues.
  • Blocked filters and shower restrictors.
  • Faulty thermocouples, igniters, elements and thermostats
