The terms "corporation stop" and "curb stop" are often used interchangeably, leading to confusion. While both relate to controlling water flow, they represent distinct components within a water distribution system. Understanding the difference is crucial for homeowners, property managers, and anyone involved in water infrastructure. This article will clarify the distinction, addressing common questions and misconceptions.
What is a Corporation Stop?
A corporation stop, also known as a meter stop, is a valve located on the water service line inside the property boundary. Its primary purpose is to control water flow to the individual building or property. This valve is typically found close to where the water service pipe enters the structure, often within a meter box or utility access area. It's usually the responsibility of the homeowner or property owner to maintain and operate the corporation stop.
What is a Curb Stop?
A curb stop, on the other hand, is a valve located on the water service line outside the property boundary, typically at the curb or near the sidewalk. Its location makes it accessible to utility workers for maintenance or emergency shut-offs. The curb stop controls the water flow to the entire service line leading to a property. The municipality or water utility company is typically responsible for the maintenance and operation of the curb stop.
Who is Responsible for Each Stop?
This is a key difference and a common source of confusion:
- Corporation Stop: The homeowner or property owner is usually responsible for the maintenance and operation of the corporation stop. This includes knowing its location and how to turn it off in case of a leak or emergency.
- Curb Stop: The municipality or water utility company is responsible for the maintenance and operation of the curb stop. While homeowners shouldn't tamper with it, knowing its location can be beneficial in emergencies.
How to Locate Your Curb Stop and Corporation Stop
Knowing the location of both your curb stop and corporation stop is crucial for safety and efficient water management. Your curb stop is typically located near the street, often marked by a small metal cap in the ground. Your corporation stop is inside your property, often near where the water service pipe enters your house or building. If you are unsure of their location, contact your local water utility company for assistance. They can help you identify them.
What Happens if One of the Stops Malfunctions?
A malfunctioning corporation stop might require repair or replacement by a qualified plumber. A malfunctioning curb stop is the responsibility of the water utility company to repair or replace. In both cases, it's essential to contact the appropriate party immediately to prevent water damage or disruption of service.
What are the Different Types of Corporation Stops and Curb Stops?
While the basic function remains the same, both corporation stops and curb stops come in various types depending on the material (e.g., brass, bronze, plastic), size, and operating mechanism (e.g., lever, key). The choice depends on factors like water pressure, soil conditions, and overall system design. Understanding the specific type installed in your property is important for maintenance and repairs.
Why is it important to know the difference?
Knowing the difference between a corporation stop and a curb stop is vital for several reasons:
- Emergency Response: In case of a water leak or emergency, knowing how to shut off the water at either the corporation stop or curb stop can minimize damage and prevent costly repairs.
- Maintenance: Understanding who is responsible for maintaining each valve ensures that repairs are carried out efficiently and correctly.
- Property Value: Proper functioning of both valves contributes to the overall condition and value of a property.
In conclusion, while both corporation stops and curb stops play critical roles in controlling water flow, their locations, responsibilities, and functions differ significantly. Understanding this distinction empowers homeowners and property owners to manage their water services effectively and safely.
