SEASENSE DUAL BILGE Y-VALVE

Now a secondary bilge pump can be added to your vessel without the need for adding another hole in your boats hull. Now you can easily use your existing thru-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 1-1/8"" bilge hose.
