Where's the shut off valve??

Imagine this, you are enjoying an evening with the family watching your favorite television show when the unmistakable sound of running water interrupts your thoughts. Natural instinct maybe to run towards the source of the leak then panic as to how to stop the water. Most people seldom think about where their house shut off valve is. This is a very important thing to know and if you purchased a new home your professional Home Inspector should point out its location.

However knowing its location and being able to get to it are two different things. How many of us have the water shut off in the basement under steps, behind boxes, or even behind access panels that need tools to open. Get to know where the shut off is and keep the access clear. If you can have it moved, move it to a more convenient location. One anyone can get to that does not require crawling and ladders to gain access of.
Another thing to consider is the type of valve you have. Most homes will have a ball type valve or a gate type valve. Most older homes will have the latter. To tell the difference the ball valve will typical have a single handle that turns perpendicular to the pipe when its closed.  This is the preferred valve to have because of its ease of use. A gate valve will have a round handle that you turn; usually red or blue in color. This valve is harder to shut off quickly.

A last thought is that just like your body; valves need exercise. When a valve is never operated sediment and corrosion will freeze the valve in place. This is more common with gate type valves. You should operate your valve every 6 months to prevent this from happening. If you try to operate your house shut off valve and find it difficult to move with moderate force then have it replaced by a professional. Use this time to have it moved to a more accessible location if need be. Never force a valve! Also be forewarned that operating gate valves can loosen the packing nut (the nut located directly below the handle) and cause the valve to weep. This can be tightened using an adjustable wrench with light force.

If you ever have doubts or questions about your house shut off valve you can always consult with a professional plumber.
