A.Y. McDonald 5133165 – Frequently Asked Questions

1) Will the A.Y. McDonald 76100-22 curb stop connect directly to 1 inch poly water service tubing, or do I need adapters?
Both ends of the 76100-22 are CTS (copper tube size) connections, so a 1 inch CTS copper or CTS-sized polyethylene service tube joins directly with no adapters. Watch the tubing call-out: poly water service is sold in both CTS and IPS sizing, and an IPS pipe will not land in a CTS end. If your service line is 1 inch IPS poly, you need an IPS-end curb stop or a CTS-to-IPS transition.
2) Is this A.Y. McDonald curb valve legal for potable drinking water service?
The 76100-22 is manufactured to No-Lead specifications for potable water service, which is what utilities and inspectors look for on a main-to-meter shutoff. It is the standard rough-in choice for residential and light commercial water service lines.
3) What is the difference between a ball curb valve and a plug or inverted-key curb stop?
A ball-type curb stop like the 76100-22 uses a rotating ball for positive full-port shutoff, so flow is unrestricted when open and the seal does not depend on a tapered plug seating in a body. Older plug and inverted-key stops are still used on many systems, but they restrict flow more and are more prone to sticking after years buried. If your utility spec calls for a specific stop style, match the spec; otherwise ball style is the common choice for new 1 inch service.
4) Where in the water service run does the 76100-22 curb stop go?
It goes buried below grade between the water main and the meter, typically at the property line under a curb box or service box so the utility or plumber can shut off the house without entering the building. Plan for a curb box and key wrench long enough to reach the valve at your bury depth, since neither is part of the valve.
5) Can I use this A.Y. McDonald 1 inch ball curb valve for a water service replacement on an existing line?
Yes, replacement of an existing service is one of its intended uses, along with new construction. The controlling detail is the existing tubing: the valve takes 1 inch CTS on both inlet and outlet, so if you are cutting into 1 inch CTS copper or CTS poly it drops in. Older galvanized or IPS-sized lines need a transition fitting or a different end configuration.
6) Which A.Y. McDonald part number do I order for the 1 inch CTS x CTS no-lead ball curb stop?
Order A.Y. McDonald 5133165, which is model 76100-22, the 1 inch CTS x CTS No-Lead ball curb valve. Both the catalog model reference and the part number describe the same item, so either will get you the right valve.
