My fireplace gas valve has a very slight leak whether the valve is on or off. The gas is leaking through the hole where the key is inserted. Is there some packing that can be inserted to eliminate the leak?

Our Answer:

Unfortunately, no. Most valves have a male threaded bushing that holds the gas stem in position. The female threads inside the valve will come factory sealed with teflon tape, pipe sealant, or may use a gasket of some sort. After removing the decorative valve escutcheon, use a deep well socket of the appropriate size to tighten the male bushing. This bushing can often become loose with repeated on/off cycles and will cause the leak you are experiencing. If you cannot tighten the bushing and the leak remains, the sealant may have dried or the internal gasket is failing. This would require replacement of the valve.
