A.Y. McDonald 702-3H2 Angle Single Check Valve, 3/4" Meter x 3/4" CTS, No-Lead

The A.Y. McDonald 702-3H2 is an angle-pattern single check valve built for water meter installations, connecting a 3/4" meter thread to 3/4" CTS (copper tube size) tubing. This No-Lead rated valve is designed to be installed at the water meter setter to prevent backflow into the utility supply while allowing service line flow to the customer side of the meter. The angle configuration allows the valve to serve as both a check valve and a directional fitting, simplifying rough-in at the meter box or pit where space is limited. As a piece of behind-the-wall/underground rough-in plumbing hardware, the 702-3H2 is intended for installation by a licensed plumber or water utility contractor as part of a meter setting assembly, not as a finished, visible fixture.

Key Features

  • Trade Size: 3/4" meter connection x 3/4" CTS outlet, sized for standard residential water meter setters.
  • Angle Configuration: The 702-3H2 is built in an angle pattern (43° angle body), allowing it to combine a directional turn with check-valve function at the meter connection, reducing the number of fittings needed in tight meter box installations.
  • Single Check Valve Function: Provides single-check backflow protection at the water meter, helping prevent reverse flow of water from the customer side back into the utility main.
  • No-Lead Construction: Manufactured to No-Lead specification, appropriate for potable water service connections.
  • CTS Outlet Connection: The 3/4" CTS end is sized to mate directly with copper tube size service tubing, streamlining the transition from the meter to the customer's water line.
  • Meter-Setter Compatible: Designed as a meter-to-service-line connector, the 702-3H2 fits standard 3/4" meter setting configurations used by water utilities and plumbing contractors.

A.Y. McDonald 5182400 – Frequently Asked Questions

1) What size connections does the A.Y. McDonald 702-3H2 angle check valve have?
The 702-3H2 runs 3/4 inch meter thread on the inlet and 3/4 inch CTS on the outlet, so it bolts to a standard 3/4 inch residential meter and transitions straight onto 3/4 inch copper tube size service tubing. The meter end is a meter thread, not NPT, so it mates to the meter swivel rather than to iron pipe.
2) Can I use the A.Y. McDonald 702-3H2 on a potable drinking water service line?
Yes. The 702-3H2 is built to No-Lead specification, which is what makes it appropriate for potable water service connections on the utility side and the customer side of the meter.
3) Is a single check valve at the meter enough backflow protection, or do I need something more?
The 702-3H2 gives single-check protection only. It stops reverse flow from the customer side back toward the utility main at the point of metering, which is the typical requirement for a standard residential service. If your jurisdiction or the hazard on that property calls for a dual check, an RPZ, or a testable assembly, a single check will not satisfy it and you want a different device.
4) Why choose the angle-pattern 702-3H2 instead of a straight inline check valve at the meter?
The angle body turns the line and checks it in one piece. In a meter box or pit where the service tubing drops away from the meter, that saves you an elbow and the couple of inches of run an inline check plus a fitting would need. If your setter geometry already runs straight through, a straight-pattern check is the simpler choice; the angle version only pays off where you need the directional turn anyway.
5) Does the 702-3H2 mount on the meter side or the customer side of the water meter?
It installs at the meter setter with the 3/4 inch meter connection on the meter and the 3/4 inch CTS end feeding the customer's service line. Flow goes through to the customer while the check blocks reverse flow back toward the utility supply.
6) Is this a finish plumbing part or underground rough-in?
Rough-in. The 702-3H2 is meter-setting hardware meant to live in the meter box or pit as part of the setter assembly, installed by a licensed plumber or water utility contractor. It is not a visible fixture valve and is not intended for finished, in-building applications.
7) What is the part number to order for the A.Y. McDonald 702-3H2 angle check valve?
Order A.Y. McDonald 5182400. That is the 702-3H2 angle single check valve in the 3/4 inch meter by 3/4 inch CTS configuration, No-Lead. The 702-3H2 designation identifies the series, the 5182400 number pins the exact size and connection combination.
