Boshart 17PFVF-300 3" FPT PVC Foot Valve with Hinged Flapper Design

The Boshart 17PFVF-300 is a 3" FPT PVC foot valve built with a hinged flapper design for suction-line installations where backflow prevention is required. This foot valve mounts at the intake end of a suction pipe, submerged in the water source, and uses a hinged flapper that seats closed whenever flow pressure drops, keeping the suction line primed and preventing water from draining back into the source between pump cycles. The PVC body resists the corrosive effects of continuous water submersion, making it a practical choice for well, irrigation, and water-transfer suction lines where a lightweight, non-metallic foot valve is preferred. The 3" FPT (female threaded) connection allows the valve to thread directly onto a matching 3" male-threaded suction pipe or nipple without additional adapters, simplifying installation at the pipe intake.

Key Features

  • Trade Size: 3" FPT connection for direct threaded attachment to a matching male-threaded suction pipe.
  • Durable Construction: PVC body construction for corrosion resistance in submerged suction-line applications.
  • Hinged Flapper Design: Internal flapper closes automatically when flow pressure decreases, preventing backflow into the water source.
  • Threaded Connection: FPT threading allows installation without solvent welding, simplifying replacement or maintenance at the suction intake.
  • Suction-Line Priming Function: Maintains prime in the suction line by keeping water from flowing back once pump flow stops.

Technical Specifications

  • Country of Origin: Taiwan
  • Packaging: 6 ea per pack
  • Connection: 3" FPT
  • Material: PVC
  • Valve Type: Hinged Flapper Foot Valve

Typical Applications

  • Well and Groundwater Suction Lines
  • Irrigation System Intake Piping
  • Water Transfer and Suction Pumping Setups
  • Residential and Commercial Suction-Side Plumbing
  • Replacement Foot Valve for 3" Threaded Suction Pipe

Why Boshart?

Boshart's 17PFVF-300 pairs a corrosion-resistant PVC body with a hinged flapper mechanism designed to reliably seal against backflow at the suction intake, helping suction lines maintain prime between pump cycles. The 3" FPT threaded connection allows straightforward installation onto existing threaded suction piping for contractors and installers working on well, irrigation, or water-transfer systems. Supplied 6 per pack, it is a practical stocking item for plumbing and irrigation supply houses serving suction-line installations.

Boshart 17PFVF-300 – Frequently Asked Questions

1) Will the Boshart 17PFVF-300 foot valve thread onto a 3 inch male-threaded suction pipe?
Yes. The 17PFVF-300 has a 3 inch FPT (female pipe thread) inlet, so it screws straight onto a 3 inch male-threaded pipe or nipple with no adapter and no solvent welding. That also means you can back it off later for cleaning or replacement without cutting pipe.
2) What does a foot valve do on a pump suction line, and do I need one?
A foot valve mounts at the submerged intake end of a suction pipe and acts as a one-way check. The Boshart 17PFVF-300 uses a hinged flapper that seats closed as soon as flow pressure drops, so water cannot drain back into the well or pond when the pump shuts off. That keeps the suction line primed for the next cycle. If your pump loses prime between cycles, this is the part that fixes it.
3) Can I use the 17PFVF-300 as a direct replacement for an existing 3 inch threaded foot valve?
If the valve you are pulling off threads onto a 3 inch male pipe end, the 17PFVF-300 drops in, because it is a 3 inch FPT connection. Foot valves that were solvent welded or that used a slip socket will not swap directly; those need the pipe end reworked to a male thread or a threaded adapter first.
4) Is a PVC foot valve OK for a submerged well or irrigation intake, or should I use brass?
The 17PFVF-300 body is PVC, which is what you want for continuous submersion in water, since it will not corrode the way a metallic body can. It is also lighter, which matters when the valve is hanging on the end of a long suction pipe. Choose a metallic foot valve instead if the application involves high temperatures or mechanical abuse at the intake, conditions PVC is not suited to.
5) Which orientation does the flapper valve need to be installed in?
The hinged flapper is directional. It goes at the intake end of the suction pipe, submerged in the water source, with flow passing up into the pipe toward the pump. Installed backwards it will hold closed against pump suction and the line will not draw. There is one threaded port, 3 inch FPT, so the pipe attaches to that end and the flapper face sits toward the water.
6) Do I need a strainer with this foot valve on a pond or open-water intake?
The 17PFVF-300 is specified as a hinged flapper foot valve, and its job is backflow prevention and prime retention, not debris screening. On an open water source, pair it with a separate intake screen or strainer; grit and leaf matter lodging under a flapper seat is the usual reason a foot valve stops sealing.
7) Is the Boshart 3 inch PVC foot valve sold individually or in a case?
The 17PFVF-300 is supplied 6 each per pack. That suits supply houses and irrigation contractors stocking a common replacement size rather than someone needing a single valve for one job.
