Boshart 17CVMF-125-100N Brass Check Valve, 1-1/4" MIP x FIP, No-Lead

The Boshart 17CVMF-125-100N is a 1-1/4" brass in-line check valve built for rough-in plumbing systems that require reliable backflow prevention on potable water lines. Configured with male iron pipe (MIP) x female iron pipe (FIP) threaded connections, this check valve installs directly into a threaded pipe run without the need for soldering or solvent welding, making it a practical choice for contractors working on residential and light-commercial water distribution systems. The 100N designation reflects the no-lead brass construction used throughout this valve, aligning it with modern low-lead plumbing requirements for potable water applications. As a rough-in component, the 17CVMF-125-100N is designed to be installed behind the wall or beneath the floor as part of the supply piping, allowing water to flow in a single direction while preventing backflow or backfeed that could otherwise contaminate a system or damage a pump.

Key Features

  • Trade Size: 1-1/4" for standard iron-pipe-sized threaded connections common in residential and commercial water lines.
  • Durable Construction: No-lead brass body resists corrosion and is suited for long-term use in potable water piping.
  • Threaded Connection: MIP x FIP (male iron pipe x female iron pipe) threading allows straightforward in-line installation into existing threaded pipe runs.
  • Check Valve Function: Permits one-directional flow, helping protect pumps, meters, and fixtures from backflow conditions.
  • No-Lead Compliance: Manufactured to no-lead brass standards for use in potable water distribution.
  • Rough-In Ready: Compact threaded body is intended for installation within wall cavities, mechanical rooms, or under-floor piping runs.

Boshart 17CVMF-125-100N – Frequently Asked Questions

1) What thread configuration does the Boshart 17CVMF-125-100N check valve have, and can I install it in an existing threaded pipe run?
The 17CVMF-125-100N is a 1-1/4 inch in-line check valve with male iron pipe on one end and female iron pipe on the other. That MIP x FIP arrangement lets it drop straight into a threaded 1-1/4 inch iron pipe run, so no soldering or solvent welding is needed. One end threads into a female fitting or coupling, the other accepts a male nipple.
2) Is this Boshart brass check valve safe for potable water lines?
Yes. The 17CVMF-125-100N is built with no-lead brass throughout, which is what the 100N in the model number refers to, and it is intended for potable water distribution. That makes it usable on drinking water supply piping rather than being limited to non-potable service.
3) Will a threaded check valve like this work for well pump backflow protection?
That is one of the uses the 17CVMF-125-100N is intended for. It allows flow in one direction only, which keeps water from backfeeding through the pump or draining the line back down. It is also used to protect meters and fixtures from backflow. Because it is a threaded brass body rather than a solvent-weld or sweat fitting, it lands well on iron pipe and galvanized runs at the pump or pressure tank.
4) Does this check valve have to be installed a certain way around?
Yes, direction matters. A check valve only passes water one way, so the body has to go in with the flow arrow pointing downstream. Get it backwards and the valve shuts off the line. Plan the MIP end and FIP end into the run accordingly, since the two ends are not interchangeable.
5) What size pipe does the Boshart 17CVMF check valve fit, and is it the same as tube size?
It is a 1-1/4 inch iron pipe size valve, so it matches 1-1/4 inch IPS threaded pipe, not 1-1/4 inch copper tube or CTS-sized PEX. If your run is copper or PEX, you need an adapter to male or female iron pipe thread before this valve will land.
6) Can this valve be buried in a wall or under a floor as a rough-in part?
It is made for exactly that. The 17CVMF-125-100N is a compact threaded body meant to be installed as part of the supply piping behind a wall, in a mechanical room, or in an under-floor run. Brass construction is what carries it there, resisting corrosion over a long service life in concealed potable water piping.
7) What is the exact part number to order for the 1-1/4 inch no-lead Boshart check valve?
Order Boshart 17CVMF-125-100N. In that number, 17CVMF is the MIP x FIP brass check valve series, 125 is the 1-1/4 inch trade size, and 100N marks the no-lead brass construction.
