The temperature and pressure relief valve is a small safety device that prevents a water heater from becoming dangerous. Here is what Davenport homeowners should know.
What it does
If the tank builds too much pressure or heat, the relief valve opens and releases water to prevent a rupture. It is the most important safety component on the tank.
Why it might drip
A valve that drips occasionally may be doing its job because the pressure is too high or an expansion tank has failed. A steady leak means the valve itself may be worn.
Never cap it
The valve must be able to open freely. Capping or plugging a relief valve removes the safety release and can turn a water heater into a hazard.
Testing it
The valve can be tested by lifting the lever briefly and letting it snap shut. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes If it will not reseat or keeps leaking in Davenport, replace it — it is an inexpensive part.
