A.Y. McDonald 5135023 7112-3YE Angle Dual Check Valve, 5/8" Yoke x 3/4" FNPT, No-Lead

The A.Y. McDonald 5135023 (model 7112-3YE) is an angle-configuration dual check backflow preventer built for water meter installations, connecting a 5/8" yoke inlet to a 3/4" FNPT outlet. This inline check assembly is manufactured to A.Y. McDonald's No-Lead standard, making it suited for rough-in service on the customer side of the meter where a compact, angled dual-check configuration is required. Plumbers and water utility contractors use this valve to provide a two-check backflow barrier directly at the meter yoke without requiring additional straight-run fitting space, since the angle body allows the connection to turn the line 90 degrees within the meter pit or setter assembly.

Key Features

  • Trade Size: 5/8" yoke inlet x 3/4" FNPT outlet, sized to mate directly with standard water meter yokes and 3/4" threaded service piping.
  • Angle Dual Check Configuration: The ADCHK/INLCK angle-body design provides an inline dual check function while allowing the connection to change direction at the meter setting, reducing the need for extra elbow fittings in tight meter pit or box installations.
  • No-Lead Construction: Manufactured to A.Y. McDonald's No-Lead (NL) specification for use on the potable water side of the meter connection.
  • Threaded FNPT Connection: The 3/4" female national pipe thread outlet allows straightforward makeup to standard threaded service line fittings without soldering or solvent welding.
  • Meter Yoke Compatible: The 5/8" yoke end is sized to fit standard residential/commercial water meter yoke connections used by water utilities and plumbing contractors.
  • Dual Check Backflow Protection: Provides a two-valve check arrangement at the meter connection point as part of the customer-side service assembly.

Technical Specifications

  • Model: 7112-3YE
  • Inlet Connection: 5/8" Yoke
  • Outlet Connection: 3/4" FNPT
  • Configuration: Angle Dual Check (ADCHK), Inline Check (INLCK)
  • Lead Content: No-Lead (NL)

  • Water Meter Yoke Installations

A.Y. McDonald 5135023 – Frequently Asked Questions

1) Will the A.Y. McDonald 5135023 dual check valve connect to a standard 5/8 inch water meter yoke?
Yes. The 5135023 (model 7112-3YE) has a 5/8 inch yoke inlet sized to mate directly with standard residential and commercial water meter yokes, with a 3/4 inch FNPT outlet on the other end. If your meter setter uses a 3/4 inch yoke connection, this is not the right valve.
2) What thread do I need on the outlet side to make up to this A.Y. McDonald angle dual check?
The outlet is 3/4 inch FNPT, so you thread a male 3/4 inch NPT nipple or adapter into it. No soldering or solvent welding involved, and no additional elbow is needed on the outlet because the body already turns the line 90 degrees.
3) Is this A.Y. McDonald check valve safe for potable water service?
It is built to A.Y. McDonald's No-Lead specification for use on the potable water side of the meter connection, which is what utilities and inspectors look for on a customer-side meter set.
4) Should I use an angle dual check or a straight inline dual check at the meter?
Use the angle body when the service line has to change direction right at the meter setting, which is the usual case in a tight meter pit or meter box. The 7112-3YE gives you both the two-check backflow barrier and the 90 degree turn in one fitting, so you skip a separate elbow and the straight-run space it needs. If your piping leaves the meter in a straight line, a straight inline dual check is the simpler choice.
5) Where in the service line does a dual check like the 7112-3YE go?
On the customer side of the water meter, right at the yoke or setter. It provides a two-valve check arrangement at the meter connection point as part of the customer-side service assembly, so the house piping cannot push water back toward the main. Typical spots are meter pits, meter boxes, and rough-in water service piping at the meter.
6) Can I use this valve to standardize dual check protection across a portfolio of residential meter sets?
Yes, provided the meters are on 5/8 inch yokes with 3/4 inch threaded service piping, which is the common residential and light commercial setting. The 7112-3YE is one part number covering both the backflow check and the turn at the meter, so it keeps a fleet of meter sets on a single No-Lead fitting. Any opening with a different yoke size or a non-threaded outlet needs a different valve.
7) What is the manufacturer part number for the A.Y. McDonald 5/8 inch yoke by 3/4 inch FNPT angle dual check?
Order it as A.Y. McDonald 5135023, catalogue model 7112-3YE. Both numbers refer to the same 5/8 inch yoke by 3/4 inch FNPT angle dual check valve, and the 5135023 is the number to quote for the No-Lead version.
