Why Your T&P Valve Dripping Is a Warning Sign

Your water heater has an important safety device called a Temperature and Pressure Relief Valve. When you notice your T&P valve dripping, it is warning you that pressure or temperature inside the tank is no longer within a safe range. Homeowners in Davis and Weber County, including Ogden, Layton, Roy, and Clearfield, often see this issue because of local water conditions.

Common Causes of a T&P Valve Dripping

A T&P valve dripping is caused by several common issues. Understanding the reason behind it helps keep your water heater safe and functioning correctly.

High Water Pressure

High water pressure is one of the main causes of a T&P valve dripping in Davis and Weber County. If the PRV on the home is failing or pressure is consistently high, the valve will open to protect the tank from excess force.

Thermal Expansion

As water heats up, it expands. In a closed plumbing system, this added volume increases pressure inside the water heater. If your home does not have a working expansion tank, the pressure has no place to go, which leads to a T&P valve dripping.

Overheating Inside the Tank

A thermostat that is not working correctly, sediment buildup inside the tank, or issues with the heating elements or gas controls can cause overheating. When the water becomes too hot, the T&P valve opens to release the extra temperature and pressure.

Hard Water and Mineral Buildup

Davis and Weber County are known for hard water. Minerals settle at the bottom of the tank and create insulation that makes the water heater work harder. This increased heat and pressure often leads to a T&P valve dripping.

A Faulty or Worn Out T&P Valve

Over time, a T&P valve can wear out. Corrosion, age, and sediment can prevent it from sealing properly. If the valve itself is failing, it may drip even if everything else in the system is normal.

Why You Should Not Ignore a T&P Valve Dripping

A T&P valve that releases water is signaling that something is not right. Ignoring the issue can lead to damage to the tank, higher utility bills, water damage, or unsafe pressure levels. A quick inspection by a licensed plumber can prevent costly repairs and keep your water heater operating safely.
