Get a new valve. There is a diaphragm in there that seals the valve and this
diaphragm has failed after 35 years of faithful service. Most people I know
have encountered this including myself.
Some have fitted a hardware store variety ball valve. If you can work out
the linkage you get a better valve at a lower price.
