What is a Curb Stop?

A curb stop, also known as a curb valve or curb cock, is a valve located near the curb or property line that allows for the control of water flow to an individual property. It is typically installed as part of the water supply system and provides a convenient access point to turn off or regulate the water supply to a specific property or building.

Key Points About Curb Stops:

• Location and Design: Curb stops are typically positioned in the ground, near the curb or property line, close to the point where the main water line enters the property. They are often housed in a small underground pit or box to protect the valve and provide easy access. The pit or box may have a cover or lid that can be removed to expose the curb stop valve.
• Function and Control: The main function of a curb stop is to control the water flow to an individual property. By turning the curb stop valve, the water supply to the property can be shut off completely or adjusted as needed. This is useful for various situations, such as emergency repairs, maintenance, or when the property is vacant for an extended period.
• Valve Type: Curb stops commonly feature a gate valve or a ball valve mechanism. Gate valves use a gate or wedge-shaped disc to control the flow of water, while ball valves use a ball with a hole that aligns with the pipe to allow water flow or closes it by rotating the ball 90 degrees. Both types are designed to provide a watertight seal when fully closed.
• Access and Operation: To access the curb stop valve, the lid or cover of the pit or box is typically removed. A special key or wrench is then used to turn the valve stem or handle. This allows the valve to open or close, regulating the water flow. Utility personnel, property owners, or authorized individuals can use this access to control the water supply to the property.
• Collaboration with Utility Companies: Curb stops are usually owned, installed, and maintained by the utility company or local water authority. In case of emergencies or repairs, it is important to contact the utility company for assistance or to request the curb stop to be operated. Utility companies may have specific procedures or guidelines for accessing and operating curb stops.
• Maintenance and Inspection: Regular inspection and maintenance of curb stops are important to ensure their proper functioning. This may include checking for leaks, corrosion, or damage to the valve, as well as verifying that the valve operates smoothly. Utility companies typically include curb stops in their maintenance programs to ensure they are in good working condition and easily accessible when needed.

Curb stops are critical components of water supply systems, allowing for localized control of water flow to individual properties. Their installation and proper maintenance contribute to efficient water management, facilitate repairs or maintenance activities, and provide a means to isolate water supply in case of emergencies or property-specific needs.

Additional Details About Curb Stops:

• Water Service Connection: The curb stop is typically located at the point where the water service line connects to the main water supply line. It serves as the interface between the public water system and the individual property’s water distribution system. The curb stop valve allows the property owner or authorized personnel to control the water flow to the property without affecting neighboring properties.
• Emergency Shut-Off: Curb stops play a crucial role in emergency situations, such as water leaks or pipe bursts. In the event of a water emergency, turning off the curb stop valve can quickly stop the flow of water to the property, minimizing damage and water loss. It provides a convenient and accessible shut-off point for emergency response or repairs.
• Property Maintenance: Curb stops are also useful for property maintenance purposes. When repairs or maintenance work needs to be carried out on the property’s plumbing system, shutting off the water supply at the curb stop prevents water from flowing into the property, allowing the work to be done safely and efficiently.
• Water Conservation: Curb stops can aid in water conservation efforts. Property owners can use the curb stop valve to regulate and control the water flow to their property, reducing unnecessary water usage. This is especially beneficial during periods of water scarcity, droughts, or water restrictions, as it allows for responsible water management.
• Property Transfers or Vacancies: Curb stops are important during property transfers or when a property is vacant. By closing the curb stop valve, the water supply to the property can be temporarily shut off, ensuring that water is not wasted or causing damage in an unoccupied building. It also provides a means of control during property handovers or when transitioning utility services between different occupants.
• Compliance and Regulations: The installation, maintenance, and operation of curb stops are subject to local regulations and requirements. These regulations may include specific guidelines on the design, location, and accessibility of curb stops. It is important for property owners and utility personnel to be familiar with these regulations to ensure compliance and proper functioning of curb stops.

Overall, curb stops provide an essential point of control and access to the water supply for individual properties. They enable efficient water management, emergency response, and maintenance activities while ensuring the responsible use of water resources. Regular inspection, maintenance, and compliance with local regulations help ensure the reliability and functionality of curb stops.
