The Kitchen sink @ work is a single ball handle disk type faucet. ( I
don't know brand )
The faucet is attached to a small instant hot water heater. located
With the handle facing you, if you pull up water discharges from the
normal spout and the
very hot water from heater comes out a small hole about 1 inch behind
the front spout.
This hole is not a normal spout (no screen or head) just looks like a
taped hole with flange.
We only want the regular spout to function when handle is straight and
have the very hot water turn on when lever is pushed to the side. Any
ideas would be appreciated.
