A leaking water pressure relief valve can cause several problems with your water heater and hot water supply. Here are just a few of the problems that are commonly associated with a leaky pressure relief valve.
1. Excessive Pressure
If your gauge is reading abnormally high levels of pressure, chances are there is an issue with the water pressure relief valve. This needs to be fixed to avoid a dangerous explosion.
2. Low Hot Water Levels
If your water is taking longer to get hot, the pressure relief valve may be leaking. While this isn't the first thing to check when you aren't getting enough hot water, it should be checked through the troubleshooting process.
3. Water Leaking on the Floor
If a valve leaks and there is no tube or a crack in the tubing you will start to see water on the floor. The problem with this is that by the time you notice the water, you may have damage to the floor under the water heater. To avoid this check any problems that seem to be happening. If you experience a rise or drop in pressure, long times between hot water recharges, or other issues, check the valve and the tubing to ensure it's functioning.
