Why is my gas water heater overflowing?
Your water heater comes with a safety feature called a “temperature pressure relief valve.” When the pressure builds up inside of your water heater, the TPR valve releases it. The TPR valve is attached to a discharge pipe that aims the overflow at the floor or ground where your hot water heater is positioned.
Where does the water from an overflow pipe go?
An overflow pipe leads from a water storage tank or cistern inside your home to the outside. They’re a vital part of your home’s plumbing system. If the water in the tank or cistern fills up to a higher level than it should, the excess water flows down the overflow pipe and runs outside, rather than leaking into the room.
What to do when your overflow pipe is leaking?
The overflow pipe could be leaking because the pressure of the water coming into the tank is too high. Use the isolation valve (see step 3 above) to turn the flow of water down. Replace the washer in the float valve. If the water feed still isn’t completely shutting off once the cistern is full, try changing the washer.
What causes an overflow pipe in a cistern to leak?
Overflow pipe leaking? When an overflow pipe is dripping or running with water, one of the most common causes is a problem with a float valve. Float valves are found in toilet cisterns, cold water tanks and central heating feed and expansion tanks.
What causes water to build up in drain line?
Underlying problems with the system can also be responsible for compromised water flow. If the pan and drain line aren’t slightly tilted, water can build up in the back of the pan and will eventually overflow. Many newer systems are equipped with overflow sensors installed within the pipe.
Is the drain pipe connected to an overflow valve?
A- This is not an “overflow” pipe. B- It is not connected to an “overflow” valve. C- It is a drain pipe connected to a Temperature & Pressure Relief Valve which is not only a legal requirement, but a critical safety device to prevent an over-pressure event (boiler explosion- google it)

Why is my hot water tank overflow pipe dripping?
If You find the hot water tank overflow pipe dripping at some point, we will have to come to an assumption that there is some sort of a defect in your overflow valve. But still, you cannot come into a solid conclusion as yet, since it is just an indication of a malfunction in your overflow valve. But we can dig deeper on this later on.
