Leaking Hot Water System Guide

Posted by on March 3, 2014

A leaking hot water heater system is more than just a minor annoyance that can be ignored for some time.

Safety Precautions

When you spot water around your water heater and want to mend the leak, take caution that electricity and water is a potentially dangerous combination. To ensure your personal safety and others with you, turn off the power to the water heater. To stop a big flood at your home, you also need to shut off the water supply before carrying out the repairs.

Safety is Critical

When you have found the area of the leak, empty the water heater tank by opening the hot water tap. This will help you to ensure that you are not accidentally scalded by hot water when fixing your leaking water heater.

Water Heater Leaking Scenarios

Leaks are usually caused by:

 1. A problem with the temperature and problem with the pressure relief valve

Insert a bucket under the overflow pipe and then open the T&P valve. Flush the valve a couple times it to clean out the debris. If water continues to leak after this, you will need to replace the valve.

 To replace the T&P relief valve, you need to check if it has been screwed on in the correct way. It can be easily unscrewed with a wrench and replaced if required. If the valve has been soldered on, you need to cut it off. Be sure to take care to ensure that there is enough pipe left over to fix the new replacement valve to it. Moreover,  this valve has been placed on the water heater for your safety. Importantly, your water heater can become a dangerous appliance and has the potential to explode.

 2. Large pressure or over heating of the T&P relief valve

 Occasionally, excessive pressure on the T&P relief valve will keep it open almost continuously, which will make water leak continuously. Simply lower the temperature of the water by reducing the thermostat setting. By lowering the heat of water will mean that the T&P valve does not have to open to relieve pressure, therefore fixing the leakage.

3. Plumbing connection leaks – inlet and outlet pipes

Firstly, check the places where the inlet and outlet pipes join the hot water heater system. The flex lines at the inlet or the drain valves at the outlet might not be joined as they should, leading to water leaks from these points. You can fasten it as needed using a tool like an adjustable wrench. However, caution needs to be taken to ensure that you do not over tighten the connections.
