A plumbing leak can quickly become a major disaster. Your water shut-off valve has the potential to protect your San Jose property from serious damage. The time to learn about this valve is well in advance of an emergency. That way, you’ll be fully prepared when a crisis arises.
What Is the Water Shut-Off Valve?
The emergency shut-off valve is an integral component of many home plumbing systems. This knob or lever can be turned to cut off the water supply to your entire home. Once you fully close the valve, no more water will flow into your home from the municipal water supply. When you no longer need to stop the flow of water, you can reopen the valve to restore your water service.
When Does the Shut-Off Valve Get Used?
A shut-off valve can be critically important in a water emergency. For example, if a pipe in your home breaks, water may spray out of it uncontrollably. You could quickly have a flood on your hands. Until the pipe is fixed, you can’t stop the flow from that spot. Rather, you might need to shut off the water supply to the entire house by closing the main valve.
A natural disaster, such as an earthquake, could also cause serious damage to your plumbing. Closing the supply valve as quickly as possible may prevent additional property problems in the wake of such an event.
It can also be a good idea to close the shut-off valve when your area experiences a water emergency, such as a water main break that requires a boil order. Closing the valve can prevent contaminated water from entering your pipes and then sitting in your water heater or your faucets.
Not all situations requiring this valve are emergencies. Your plumber may also need to turn off the water supply while doing work in your home. The shut-off valve provides a simple way to achieve a temporary interruption in water service for the sake of home repairs.
Where Is Your Emergency Shut-Off Valve?
Water shut-off valves differ greatly from one home to the next. You should take the time to find out where yours is and what it looks like.
Some shut-off valves are inside the home. If you have a basement or a crawl space, yours might be in that area. If you don’t have a basement or a crawl space, the valve could be somewhere on the lower level. Typically, indoor shut-off valves are on the foundation level and close to an exterior wall.
In other homes, the shut-off valve could be in the garage. If your water tank is in your garage, that’s a good place to check for the valve.
Emergency shut-off valves can also be located outside. Look for the supply pipe that brings water into your home from the municipal supply. The shut-off valve may be near it. Some homeowners can turn off the flow from the water meter itself.
Valves can also be located in your yard. You might find the handle for turning off the supply somewhere along your property line.
It might be easier to identify your shut-off valve if you knew exactly what to look for, but the appearance of the handle can vary greatly. It might be a lever that you turn at a 90-degree angle. It could also be a knob or a wheel that must be turned multiple times. Shut-off mechanisms inside water meters may involve a smaller switch that requires the use of pliers or a wrench.
Once you locate your shut-off valve, it is a good idea to clearly mark it. Consider hanging a colorful tag on the handle so that you’ll be able to quickly find it in an emergency. Make sure that everyone in your family knows where it is as well. You could also practice opening and closing the valve a few times. It’s important to close the valve completely to prevent small leaks, and practicing can help you get a feel for how firmly you need to turn the handle.
What Are the Different Types of Shut-Off Valves?
There are both manual and automatic shut-off valves available for residential plumbing systems.
Manual emergency shut-off valves are the ones that you turn by hand as soon as you notice a problem with your plumbing. They include dials and levers that control the opening and closing of your main valve.
Automatic shut-off valves use sensors to detect a problem with your plumbing. When the pressure in your system drops below a certain level, it triggers the automatic valve to close. This can be invaluable in leak situations. For example, if the leak is in a bathroom that doesn’t get used very often, you may not notice the puddle until it starts to drip through to the next level. If you’re out of town when the problem begins, the flood could go unchecked for even longer. In such situations, you might find yourself incredibly grateful for the protection provided by your automatic valve.
Automatic shut-offs are used in addition to manual ones. The manual valve still provides the option to turn off the water supply by hand when you need to have plumbing work done on your home or there’s a boil order in your area.
If your home does not have an automatic emergency shut-off valve, you may be able to add one. Talk to your San Jose plumber about the benefits of upgrading your plumbing with an automatic valve.
Do All Homes Have Water Shut-Off Valves?
No, some homes are not equipped with water shut-off valves. For example, not all older houses include such valves as a part of the plumbing system. Also, people who live in apartment buildings or manufactured homes may not have access to a shut-off valve.
If your house does not have its own shut-off valve, the supply may need to be cut off at the street when an emergency arises. Your water company might be responsible for taking care of that, but you may need to call first. It’s a good idea to ask your water company ahead of time how you should handle such a situation.
Your home may also be a good candidate for the installation of a shut-off valve. You can ask your plumber whether that is something that could be added to your plumbing system.
If you’re not sure where your emergency shut-off valve is — or whether you have one at all — now is the time to find out. Taking this preventative step can help protect your home from a major water disaster at some point in the future. For help, call a plumber in San Jose.
