hot water heater leaking from overflow pipe

The temperature should be around 120 degrees. Run the water for one minute and use a meat thermometer to take the temperature reading. To check the water temperature, ensure you turn on the hot water faucet. However, the water has to be near the boiling point. High water temperatureĪlthough rare, your water heater’s pressure relief valve could be leaking as a result of excessively high temperatures. Luckily, this can be solved by installing an expansion tank that gives the pressure an outlet other than a pressure relief valve. But with nowhere to go, the valves open to relieve the pressure. This means that when the water is heated, the pressure increases as it should. If you get a high-pressure reading, then you could be dealing with a closed plumbing system issue. If the water pressure is normal and the leak is persistent, then high water pressure is not the cause of the leak. If the gauge shows a psi reading of 150 and above, then the cause of the leak could be high pressure. The pressure reading should be between 40 psi- 80 psi. For this, ensure you purchase a pressure gauge that is designed for garden hoses. However, one of the easiest places to connect the pressure gauge is the outdoor hose faucets. To test the pressure, use a pressure gauge and attach it to either the cold-water pipe or the hot water pipe. However, if you are not comfortable checking the water pressure, you can always contact your technician. This necessitates the need to test the pressure in your water heater. As excess pressure is relieved out of your water heater system, some water may leak. In some cases, a water heater’s pressure relief valve may leak because it is functioning as intended.

High water pressureĪ leaking valve is not always a broken valve. SCHEDULE SERVICE What are the causes of leaking water heater pressure valves? 1. In water heater pressure relief valves, the valve is set to open when the pressure exceeds 150 psi. A malfunctioning valve can cause the water heater to explode and is the major cause of water heater explosions. The pressure relief valve gives steam and water a chance to escape when either the pressure or temperature in the water tank gets too high.

What is the importance of a water heater’s pressure relief valve? And all these must be addressed immediately given the high risks of property damage and hazards that can occur if the issue is ignored. However, there are many causes of leaks in water pressure relief valves. While some people tend to panic and get help immediately, others may just shrug their shoulders and assume that the leak is a common occurrence. A leak from your water heater’s pressure relief valve is a major concern, especially if it’s the first time dealing with this problem.
