A slow leak in the boiler, piping, or a radiator valve will drop pressure over time. Leaks can be hard to spot.
Pressure Relief Valve
A faulty pressure relief valve can vent water and drop pressure.
Expansion Tank
A failed expansion tank causes pressure swings as the water heats and cools.
When to Call a Professional
