The terms "corporation stop" and "curb stop" are often used interchangeably, leading to confusion. While both refer to valves used to control water flow, they differ significantly in location and function. Understanding these differences is crucial for homeowners, plumbers, and anyone involved in water infrastructure management. This comprehensive guide will clarify the distinctions and answer frequently asked questions.
What is a Corporation Stop?
A corporation stop, also known as a meter stop, is a valve located inside your property line, usually near the water meter. It's the valve responsible for controlling the water supply specifically to your individual home or building. This means turning it off isolates your property from the main water line, preventing water flow only to your building. It's typically a smaller valve than a curb stop, often made of brass or other durable materials. Plumbers usually access and work on corporation stops from inside your property.
What is a Curb Stop?
A curb stop is a valve located at the edge of your property, typically underground near the curb or sidewalk. It's placed on the water service line, which connects the main water supply to your home's corporation stop. The curb stop's primary function is to control the water flow to your entire service line. This means that shutting off the curb stop cuts off water to both your house and everything between the curb stop and your home. It's usually larger and more robust than a corporation stop, often made of materials designed to withstand the rigors of being buried underground. Accessing and operating a curb stop usually requires specialized tools and may necessitate digging.
What's the Difference Between a Corporation Stop and a Curb Stop?
The key difference lies in their location and control. The corporation stop controls the water supply to your individual property, while the curb stop controls the water supply to the entire service line leading to your property. If you have a leak inside your house, you can usually shut off the water with just the corporation stop. However, for a leak on the service line between the curb and your house, you would need to shut off the curb stop.
How Do I Locate My Curb Stop?
Locating your curb stop can be tricky. It's usually buried underground near the curb, often marked with a small metal cap or a slightly raised area in the pavement. If you can't locate it, consult your local water utility company. They can assist in identifying its location or even send a representative to pinpoint it for you.
What Happens if My Curb Stop Breaks?
A broken curb stop can be a serious issue, resulting in water leaks and potential water damage to your property and the surrounding area. If you suspect a problem with your curb stop (e.g., significant water leaks, difficulty turning it), contact your local water utility company immediately. They are equipped to handle repairs and replacements.
Who is Responsible for Repairing a Curb Stop?
Typically, the responsibility for repairing or replacing a curb stop falls on the water utility company, as it's part of the main water infrastructure. However, damage caused by homeowner negligence may shift the responsibility and associated costs to the homeowner. Always check your local ordinances and contact your utility company to clarify responsibilities.
Can I Repair My Curb Stop Myself?
Repairing or replacing a curb stop is generally not recommended for homeowners without specific plumbing expertise. These valves are underground, and improper handling can lead to further damage or even water main breaks. Leave such repairs to qualified plumbers or water utility personnel.
Why is it Important to Know the Difference?
Understanding the difference between a corporation stop and a curb stop empowers you to handle water emergencies effectively. Knowing their locations allows for quick responses to leaks, saving you potential property damage and inconvenience. It's a crucial piece of knowledge for every homeowner.
