              Description

              Forespar ® Y-Valves and Connectors are molded from Marelon ®. Offering an improved, stronger handle design, our valves are available in 1" (25.4 mm) and 1 1/2" (38.1 mm) barb size. Y-Valves are an essential piece of equipment when the flow of water or other fluids are required to be conveniently diverted, as in a marine head application where a holding tank is utilized. They are easily mounted to a bulkhead. The valves are operated by a simple 120° movement. Positive stops are provided between positions.

              Features:

              • The use of a Y-Valve can eliminate the need for an extra pump and the associated cost of wiring and installation
              • Applications:
                • Wash-down systems and bait tank aeration
                • Marine head application where a holding tank is utilized
              • Glass-reinforced marelon construction (The only synthetic material to pass the stringent Marine U.L. testing)
              • Easily mounted to a bulkhead
              • Incorporates an improved, stronger handle design
                • Handle design makes it easy to see "flow" direction
                • Positive stops are provided between positions

              Specifications:

              • Type: Flange Mount
              • Material: Glass-reinforced Marelon

              Note: MF Series Y-valves should not be installed below the waterline. Forespar's Pro Series Y-Valve seacocks are ideal for this.

              Rated 5 out of 5 by from Great selector valve! This valve mounts to a bulkhead and splits one source into two outlets. I used to select between sending my 1 inch electric toilet outlet to the tank or overboard discharge. I also used the 3/4 inch variation to use my shower pump for its intended purpose and with a turn of the valve I can use the same pump as an auxiliary bilge pump. This helps suck out the little bit of water that the standard bilge pump leaves behind. These are solid valves that work great for fresh or salt water use. Easy to identify the flow path and easy to operate with one hand.

              Questions

              Is this diverter suitable for use as a fresh (potable) water fill diverter, so that one of two different tanks can be selected for filling?

              Asked by: Plain Tom
              Thank you for reaching out to the Defender Team! This Forespar MF-Series Diverter Y-Valve Connector is recommended for wash-down systems, bait tank aeration and marine head applications where a holding tank is utilized. You would want to make sure you find a Y-diverter that specifies it's for potable water.
