When a Hot Water Service heats water, the energy it produces creates steam which forms pressure in the tank. Hot Water Systems are designed to hold an amount of pressure and a temperature and these amounts are engineered by the manufacturers. When these amounts are exceeded, the TPR Valve will leak and water will flow down the drain tube.

TPR Valves are generally located at the top of your Hot Water Service, either on the side at the top or on the very top. There is a lever attached to the valve that when pulled will release pressure by discharging water from your hot water heater cylinder via a drainpipe to ground level - usually above a drain.

As we have said, it is critical that this valve is working perfectly at all times. So, it’s recommended to test your TPR Valve once every 6 months. Failure to operate the easing lever on the relief valve may result in the water heater cylinder failing, or even exploding.

Simply lift the lever located on the TPR Valve until the water runs freely down the drain line, then gently lower the lever back down again. It should seal shut. It is possible at times for the seat on the TPR Valve to be obstructed by sediment causing the valve to continually leak, if this happens then repeat the above step until the valve seals shut.

If water does not flow freely from the drain line when the lever is lifted, then the water heater must be checked by a licensed plumbing professional.

The TPR Valve should only be replaced by a licensed plumber within every 5 years. TPR Valves have different ratings and hot water systems require specific TPR Valves as per the manufacturers specifications. An incorrectly installed TPR Valve is extremely dangerous and could cause your hot water system to explode, causing harm to you, your family and your home. Don’t risk it, always use a Master Plumber.

As the name suggests a TPR Valve has a primary purpose to monitor the pressure and temperature of your hot water. If either the pressure or temperature within the hot water service are outside their pre-set parameters, the TPR Valve will leak. This not only prevents damage to your hot water heater but gives you a visual indication that something is wrong with it.

Hot Water Systems are made up of many parts and components that ensure the safe delivery of reliable and consistent hot water throughout your home. One of these components is a Temperature Pressure Relief Valve, more commonly known as a “TPR Valve”.

So, it’s critical for safety reasons that these valves are routinely inspected and maintained in good working order or your Hot Water System could be at risk of exploding and causing serious harm and damage.
