A.Y. McDonald 5182-052 1" CTS Ball Curb Stop Valve

The A.Y. McDonald 5182-052, referenced under model 76100Q, is a 1" ball-style curb stop configured for CTS (copper tube size) connections on both ends. Curb stops are installed in the underground water service line between the main and the building, giving a plumber or utility crew a dedicated shutoff point at the curb box. This 1" CTS ball configuration is built for rough-in and underground service line work rather than exposed above-grade plumbing, and it is sized to mate directly with 1" CTS copper or compatible tubing runs commonly used in water service laterals.

Key Features

  • Trade Size: 1" connection sized for 1" CTS copper tube size service lines.
  • Connection Type: CTS end connections on both inlet and outlet for direct tube compatibility without additional adapters.
  • Valve Configuration: Ball-style shutoff mechanism (BALL CURB) for full-flow, quarter-turn on/off operation at the curb stop location.
  • Curb Stop Application: Designed to be installed in the underground water service line as the dedicated shutoff between the main and the structure being served.
  • Model Reference: Cross-referenced to A.Y. McDonald model 76100Q for the 1" ball curb stop configuration.

Technical Specifications

  • Trade Size: 1"
  • Connection: CTS x CTS
  • Valve Type: Ball
  • Model Cross-Reference: 76100Q

Typical Applications

  • Underground Water Service Line Shutoffs
  • Curb Box and Curb Stop Installations
  • Residential and Commercial Water Service Rough-In
  • Service Line Replacement and Repair Work
  • New Construction Underground Utility Connections

Why A.Y. McDonald?

A.Y. McDonald is a long-standing name in waterworks and plumbing supply, and the 5182-052 ball curb stop is built for the demanding underground service environment where a dependable, full-flow shutoff is required. Plumbers and contractors specify curb stops like this one when a reliable CTS-to-CTS connection point is needed at the property line, giving utilities and property owners a way to isolate the service line for maintenance or emergency shutoff. Choosing A.Y. McDonald for this rough-in component means matching your 1" CTS service line with a curb stop built specifically for that connection standard.

A.Y. McDonald 5182-031 – Frequently Asked Questions

1) Will the 5182 curb stop connect straight to 1 inch CTS copper service tubing, or do I need adapters?
The 1 inch version (5182-052) has CTS ends on both inlet and outlet, so it mates directly with 1 inch copper tube size service line without adapters. If your lateral is 3/4 inch CTS, order the 5182-031 instead.
2) Is the A.Y. McDonald 76100Q the same valve as the 5182-052?
Yes. The 5182-052 1 inch ball curb stop is cross-referenced to A.Y. McDonald model 76100Q, so a spec or takeoff calling out 76100Q for the 1 inch CTS ball curb stop is the same configuration.
3) Can I use this curb stop for an above-grade shutoff inside a building?
No. The 5182 is built for the underground water service line between the main and the structure, operated from a curb box. For an exposed above-grade shutoff, use a standard ball valve or stop rated for that service instead.
4) Ball curb stop or an older plug-style curb stop, which should I install?
The 5182 is a ball-type curb stop: quarter turn, full port flow, on or off with no throttling fuss. Plug or ground-key style curb stops are the older pattern that many utilities are moving away from. If your jurisdiction accepts a ball curb stop on the service lateral, the ball design gives you unrestricted flow at the shutoff point.
5) Is this the right valve for a lead service line replacement at the property line?
It suits that work. Curb stops in the 5182 family are specified for service line replacement and repair, new construction underground utility connections, and residential or commercial water service rough-in, giving the utility or owner a point to isolate the lateral. Size it to the new copper lateral: 3/4 inch or 1 inch CTS.
6) Does the curb stop come with a curb box or operating key?
No. The 5182 is the valve only, CTS by CTS. The curb box, extension, lid, and the operating key or wrench used to turn it from grade are separate items you order alongside it.
