I have a gate valve with a small leak I need to fix. The valve is
stainless and in good condition but has a very small leak when closed
tightly. It's a 3" valve with a non-standard flange so replacement is
out of the question. The valve will be seldom operated and I could live
with a fix that sealed the valve tight and allowed the valve to be
opened ONCE (for a fire hose connection).
The big complication is that the valve is welded together and cannot be
I was thinking of putting a thin sheet of plastic on the gate, but if it
washed off when opened it might jam something. Maybe just a thin bead
of silicone on the upstream side? It's a water gravity system with only
5' of water head so pressure is extremely low.
