I live in an apartment with two steam or hot water radiators. I believe they are steam radiators because there is only one pipe going into each radiator. My problem is twofold: 1) Each radiator has a new "vapor equalizing valve" that releases not only steam, but water quite frequently. I need to keep a pot underneath to catch the water, but it's spilling and damaging my wood floors. The problem is not only the water release, but the frequency with which the release occurs.
2) Although it seems to happen less since the new valves were put on, the radiators bang extremely loudly. After reading some of the answers on this site (particularly from Harold K.), it appears I might have to lift the radiators and slip some new wood dowels or something underneath. How can I best do this myself?
