A.Y. McDonald 712-3Y2 Series Angle Stop Supply Valve

The A.Y. McDonald 712-3Y2 series is a family of angle-pattern shutoff valves built for rough-in supply line installation behind the wall or under the fixture. This listing covers the 712-3Y2 series models, including 712-3Y233, 5124-039, 5124-040, and 5182-358, so plumbers and contractors can select the correct cross-referenced part for a given job. As an angle-configuration valve, each model in this series turns the supply line 90° from the wall or floor stub-out to the fixture riser, eliminating the need for a separate elbow fitting and simplifying the rough-in. The 712-3Y233 model specifically cross-references to A.Y. McDonald catalog number 5135-309 for parts lookup and ordering, and other models in the series carry their own established cross-reference numbers used by the trade for replacement matching.

Key Features

  • Angle Configuration: Every model in the 712-3Y2 series is built in an angle pattern, turning the supply line 90° from the rough-in stub-out to the fixture connection point — a common requirement for under-sink, toilet, and appliance supply installations.
  • Model Range: Available across the 712-3Y2 series in the following models: 712-3Y233, 5124-039, 5124-040, and 5182-358, allowing selection of the exact cross-referenced part needed for a given installation or replacement.
  • Model Identification: The 712-3Y233 model is identified under A.Y. McDonald model 712-3Y233 and cross-references to A.Y. McDonald catalog number 5135-309 for parts lookup and ordering.
  • Shutoff Function: As supply stop valves, the 712-3Y2 series provides a dedicated point-of-use shutoff, allowing a plumber or contractor to isolate an individual fixture supply without shutting down the entire building water service.
  • Rough-In Application: Intended for behind-the-wall or under-fixture installation as part of the finish plumbing rough-in, connecting the building supply stub-out to the fixture riser or braided connector.
  • A.Y. McDonald Manufacturing: Sourced from A.Y. McDonald, a long-established manufacturer of waterworks and plumbing supply products used by professional plumbers and contractors.

A.Y. McDonald 5124-039 – Frequently Asked Questions

1) What models are in the A.Y. McDonald 712-3Y2 angle stop series?
Four models make up the 712-3Y2 series of angle stop supply valves: 712-3Y233, 5124-039, 5124-040, and 5182-358. Order by the model number that matches the part you are replacing or the one called out on your rough-in sheet, since each is its own established trade cross-reference.
2) Do I still need an elbow fitting with an A.Y. McDonald 712-3Y2 stop valve?
No. Every model in the 712-3Y2 series is an angle-pattern valve, so it turns the supply 90 degrees from the wall or floor stub-out to the fixture riser on its own. That is the whole point of the angle body, and it takes a separate elbow out of the rough-in.
3) Can I shut off one sink or toilet with this valve without killing water to the whole building?
That is exactly what the 712-3Y2 series is for. These are point-of-use supply stops, so you isolate the individual fixture supply and leave the rest of the building service running. Useful for property managers and maintenance crews servicing one unit at a time.
4) Where in the job does a 712-3Y2 angle stop get installed?
It goes in during finish plumbing, behind the wall or under the fixture, connecting the building supply stub-out to the fixture riser or a braided connector. Typical spots are under-sink, toilet, and appliance supplies, on both new construction and renovation work.
