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.

Note: Water discharged from the TPR Valve drain line will be hot! Exercise care to avoid any splashing of water by standing clear of the drain line’s point of discharge when operating the valve’s easing lever.

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.

If after 3 to 4 attempts the valve continues to run, then it’s time to call our expert Hot Water Plumber at Essendon Plumbing Services.

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.

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.

Virgin Engineers is a notable manufacturer, supplier ad stockist of Dielectric Unions in Mumbai, India. Dielectric Union are utilized in commercial and residential applications to prevent galvanic and stray currents from accelerating corrosion and degradation in the pipe system. It is inserted between two pipes composed of different metals. Dielectric unions are available in a variety of designs, sizes, and materials.

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.

Union nut and union body are put together by sliding the rubber gasket between them. You should clockwise-twist the union nut with a pipe wrench.

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.

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.

A-To prevent galvanic corrosion, two-part fittings of different metals that are electrically insulated from one another are referred to as dielectric unions. The phrase is frequently used to refer to a group of plumbing pipe fittings. Two distinct metals exposed to an acidic solution can experience galvanic corrosion. A current of electricity flows between the two metals as a result of this mixture, which functions as a battery.

A dielectric union is a special adapter or fitting used in various metal pipe systems to isolate the connection of dissimilar metals. An elastomeric rubber gasket seals the connection, and a plastic composite material separates the copper tube connection from the dielectric union's hex nut. When different metals come into touch with each other, they begin to corrode. The little amount of acid in water initiates the electrolytic reaction between the two metals, causing electrons to flow from one metal to the other. This eventually leads to galvanic corrosion. To prevent this from happening, a dielectric union is employed to connect the two dissimilar metal pipes.

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”.

Install the copper solder adapter onto the copper pipe, then melt the copper solder adapter to the copper pipe with a propane flame. Try to keep the plastic insulator as far away from the torch as possible to prevent the melting the insulator.

A Drain-Net drain strainer captures all the food scraps and solid waste that would otherwise clog your floor drains.

A-In an electrolytic reaction, water serves as the electrolyte and occurs when two dissimilar metals come into contact. Corrosion then starts to occur in the metals. Galvanic corrosion is what this is. The pipes made of various metals are joined together using dielectric unions to avoid this happening. When there is poor water quality and galvanized materials have a high probability of corroding, brass is frequently utilized for fittings for copper pipes. Brass is sensitive to acidic water despite being rust-resistant.

A-Cover the threads of the steel pipe with many layers of pipe sealing tape. The steel pipe should be connected to the threaded end of the dielectric union body. A pipe wrench should be used to tighten the union as you turn it clockwise.
