Why does my hot water heater overflow keep discharging water?
Causes of Excess Pressure in a Water Heater Since water expands as it’s heated, higher-temperature water occupies more volume, which, in the confines of a water heater, results in increased pressure. If the pressure increases too much, your relief valve will activate, releasing water through the drain pipe.
Why is hot water running out of my overflow pipe?
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. When the water in the tank is used, its level goes down and so does the ball and arm.
Why does my water heater keep running water?
Reasons Why Your Water Heater is Constantly Running Your water heater might have insufficient insulation – If the water heater is not properly insulated, it will be unable to maintain the water temperature. Your water heater might have sediment build-up – Over time sediment builds up in the bottom of your water heater.
How do I stop my water heater from overflowing?
First, turn off the gas to the water heater, or flip the breaker if it’s electric. Close the cold water cut-off valve going into the water heater. Open the valve at the bottom and the pressure relief valve for a minute to drain a little water out of the tank and relieve the pressure.
How do I stop my hot water cylinder from overflowing?
Find the PTRV valve on the side of the cylinder near the top or bottom, then lift the silver lever three or four times to open, close and clear any blockages. If the water flow comes to a stop then your problem is solved. But if it keeps running then you probably need to replace the valve.
Is it normal for a water heater to release pressure?
It’s totally normal for the water and water heater to expand to a certain extend. After all, this is what naturally happens when the temperature rises. However, when the temperature is 210 degrees—or the pressure is 150 pounds per inch (psi)—this is far too much pressure and heat in the water heater.
Why won’t my water heater shut off?
There are a couple potential reasons why your heating system won’t turn off: Bad thermostat: A faulty thermostat can normally be repaired. Faulty wiring, a broken switch, or broken heating sensor can be fixed depending on how severe the issue is.

Why is my water heater relief valve leaking?
Your water heater’s relief valve can start leaking for one of two reasons: either the valve was triggered to open because of excessive temperature or pressure, or the valve itself is faulty. If the problem is a faulty valve, then you might have an actual leak.
Why does my expansion tank keep filling up?
Not Enough Air in Diaphragm Tank The most common expansion tank problem in a diaphragm tank is losing small amounts of air through the valve. If the tank does not hold its air pressure after you complete this fix or it fills with excess water, you may need to replace the diaphragm.
