Stop Valves

Stop valves, aka globe valves, are only meant for water. They’re commonly found at plumbing fixtures, such as the water supply
line to your toilet or as part of your outside faucet. A stop valve works by moving a stopper up and down. The photos below show a
stop valve in the open position, halfway open position, and fully closed position.
Open or closed: To know if the valve is open or closed, take a look at the stem. If you carefully examine the stem in the photos
above, you’ll see that when the valve is fully closed, the stem isn’t visible at all. Most stop valves are much smaller than the
one pictured above, but I decided to use a larger one for my example because it gives the best view. The photo below shows an
exploded view of the guts of a stop valve.

Stop valves take several hand movements to operate and they tend to get difficult to operate over time. They also leak when they haven’t been touched in a while. For this reason, no home inspector should ever touch one of these valves. Yes, I’ve learned the hard way. If you have a leaking stop valve, you can often stop the leak by using a wrench to tighten the nut right below the handle. Lefty loosey, righty tighty. But this won’t always stop the leak, because sometimes new packing is needed.
