Have a pressure relief valve located on the pressure tank for my well water. This is a 75psi fixed valve. Water has started to drip from this valve, not much but leaking none the less. The pressure gauge on the tank is set at 60psi. Pressure relief valve is approx. 14yrs old. So is this just a valve that needs to be replaced or is this a sign of something else, maybe pressure guage is faulty? Replacing the valve looks pretty straight forward.
Thanks in advance.
UPDATE: Replaced valve over the weekend, pretty straight forward. Looked at the old valve and there is a screw that holds a gasket in place that sheared off. New valve from HD was $18.
