Add a second bilge pump with the SeaSense® Dual Bilge Y Valve to your existing discharge hose!
Now a secondary bilge pump can be added to your vessel without the need for adding another hole in your boats hull. You can easily use your existing through-hull hose!
Our Y Valve consists of two one-way check valves that allow for the use of either bilge pump individually, or both simultaneously without the risk of back flow. It will accept both 3/4" and/or 1 1/8" bilge hose.
*Includes 2 check valves to prevent back flow
