UNDER SINK VALVES
UNDER SINK VALVES: Under-sink valves are sometimes
called "angle stops". An angle stop is
a water shut-off valve which has an inlet and
outlet which are 90 degrees to one another.
These are commonly used for water closets and
under sinks as local water shut-off points. Some
under-sink valves are, of course, not the angle
stop type but serve the same purpose. Sometimes
these valves get such little use that often they
will corrode and refuse to turn. When a stuck
valve is turned the handle or stem could break.
For this reason the inspector is not allowed to
turn an under-sink valve on or off. If the valve
is not leaking, it usually is a sign of a
sufficient installation. The valve may, however,
still be corroded and may refuse to turn. When
this is the case, it would be necessary to turn
the main valve off to make repairs to fixtures.
