Hot water system TPR valve repair and replacement

hot water system trp valve replacement sydney

What is the purpose of a TRP valve in a hot water system?

The temperature and pressure relief valve (TPR valve) in a hot water system is an important and necessary safety feature with it’s main function being to release excess pressure and temperature from the water heater tank to prevent a catastrophic failure or explosion.

As water is heated, it expands, creating pressure within the tank. If the pressure inside the hot water tank becomes too high, the TPR valve automatically opens, releasing the excess pressure to the outside.

Additionally, if the water temperature inside the tank becomes too high, the TPR valve will also open to release the excess heat.

The TPR valve is typically located on the side or top of the water heater tank and is connected to a discharge pipe that runs to a drain or to the exterior of the building.

It is important to ensure that the TPR valve is properly installed and functioning correctly because, as indicated above, failure to do so can result in a dangerous situation.

Save time and money by employing a local hot water expert

Did you know that often the repair and installation of a hot water system requires the expertise and qualifications of both a licensed plumber and a licensed electrician?

We are qualified to undertake any plumbing and electrical work required to ensure your hot water heater is repaired quickly and within budget. Plumbers who do not specialise in the installation of hot water heaters may need to outsource the electrical work required to another tradesperson, thereby holding up your hot water system repair or installation, adding extra expense due to additional call-out fees charged by employing two tradespeople.

Your hot water heater is an expensive appliance. Don’t risk voiding your warranty.

Additionally, most manufacturers won’t cover the terms of your hot water system warranty if it isn’t installed by a licensed hot water technician or a qualified plumber. Hot water tanks are an expensive appliance so why would you risk voiding your warranty by installing it yourself or employing the services of someone who isn’t licensed?
