Things to know about installing, maintaining, and repairing hot water systems

1. PTR valves

PTR valves, tempering valves and pressure limiting valves must be replaced at intervals NOT exceeding five years.

It is, however, possible for these components to fail in less than five years. In this case they will have to be replaced sooner. These manufacturing guidelines are put in place to protect not only the unit, but you, your family, and your home, too.

2. Your hot water system’s life expectancy

Excessive water pressure, extreme temperatures, or poor water quality can negatively impact the life expectancy of your hot water system. This means you might require frequent and inconvenient hot water repairs.

Do you find your current hot water system is susceptible to frequent failures? There are three common culprits for inconvenient, repeat repairs:

Poor water quality:

If you have old, galvanised water pipes you’re probably filling your hot water service with rusty sediment causing the cylinder to corrode at a faster rate.

In this case, you likely have poor water pressure, too.

We can fix this by replacing your cold supply pipe from the water meter to all the cold outlets in your home. That might sound complicated and expensive, but for an average home, it’s actually quite a simple process that can be completed in a day!

Excessive water pressure:

Pressure limiting valves (PLVs) should be fitted when the water supply pressure exceeds the
specifications provided by the manufacturer.

We recommend fitting a 500kpa PLV to your water meter so to equalise the hot and cold outlets. This means cold will not override the hot, as it often can when the hot water service has a pressure limiting valve only. This allows you to easily adjust shower temperatures.


Tempted to turn the temperature of your hot water service up to the highest setting? That might sound good in theory, but doing this doesn’t necessarily produce a larger volume of hot water. Additionally, the excessive heat actually shortens the life of the unit.

It’s best to set the thermostat at the specific manufacturer’s recommended setting. This is usually around 55-60°C.

If you have children, we recommend fitting a tempering valve. This valve limits the temperature to 50°C and acts as an anti-scalding device. Did you know that all new houses must have tempering valves fitted to hot water lines that supply bathrooms?

Tempering valve installations are also required when changing hot water units from one type to another in existing homes (for example, decommissioning an indoor gas storage unit and fitting a gas instantaneous unit outside.)

The only time a tempering valve is not required on a hot water service installation (on existing homes built before the mandatory use of tempering valves) is when the unit is a direct change over (for example, removing an old gas storage cylinder and fitting a new gas storage cylinder in exactly the same location.)

3. You MUST have a safe tray installed!

Indoor hot water services must be installed on a safe tray with a drain outlet or terminator valve.

A safe tray is a crucial tool that protects your home from flooding and water damage in the case of a leaking or burst hot water service. If you have an existing indoor hot water service without a safe tray we recommend that you have one fitted ASAP! Or, you can choose to instead have an external hot water service installed.

4. Get the right advice from the pros

Changing your storage hot water service for an instantaneous hot water service is generally more involved than most people think.

More often than not, your gas line needs to be upgraded to a larger diameter pipe when changing from a storage hot water service to an instant hot water service. This is because the gas supply demand on an instant hot water unit can be up to five or six times greater than that of a storage type unit.

Although instant hot water units are generally cheaper to run, the additional costs of a gas line upgrade must be considered.
