Installing a hot water system may appear to be a doable job, but keep in mind there are many mistakes you can make, as the process involves a few aspects that require special attention. For installing hot water systems in Perth, keep in mind the following problems you may encounter –

Using the right fittings

It is important to assess the exact requirements of the type of hot water system you want to install. Details such as brass or copper tank connectors, galvanised nipples, etc. all require special fittings. If these details are ignored, chances are the pipes will weaken down the line and leaks will occur.

Proper soldering of connections

Be cautious when soldering the connections. If this task is performed too near the tank itself, the heat can also melt any plastic fittings on the tank.

Fill the heater with water before switching on

Many first-time users make the mistake of switching on the heater electrical connection, before filling the tank with water (by opening up the tap). In such a case the heating elements in the heater will get burnt out, making the same inoperable.

Need for an overflow T&P tube

T&P is a relief valve which is required in all water heaters. It is a safety feature designed to protect the tank from bursting and spraying scalding water on anyone in its vicinity.

Valves controlling pressure and temperature

If the above valves are misconnected, you run the risk of being scalded with hot water spray. To avoid It, the valves have to be connected to a pipe that is watertight and extends to within six inches of the floor.  A separate overflow tube fixed at the top and snaking down the side of the tank up to the floor will help to prevent such a problem.

Basic security requirement

When installing a hot water system, you need to make sure it is securely fixed to the tank frame. Such secure fixing will ensure there is no falling or tipping if an earthquake or other such calamity occurs.

When it is time to look at purchasing a replacement water heater

Probably your existing water heater will nudge you when it can no longer perform fault-free. Check for the following warnings signs –

  • The water is not heating to the required temperature
  • The water colour is not clear or looks rusty
  • The water does not heat up at all
  • Strange noises being emitted while the heater is operating
  • Metallic taste and strange odour of the water
  • Leaks noticed around the water heater

Besides all the above, if your hot water system is over ten years old, it has more or less run its life expectancy, and you should look at replacing the same.

As mentioned above, installing a hot water system is not an easy job.  Every home requires a water heater, so to avoid any dangerous and problematic situations cropping up it would be wise to use the services of a professional – someone who will ensure proper and safe installation.
