Jabsco 12V Solenoid Anti-Siphon Valve for Toilets

The Jabsco 12V Solenoid Anti-Siphon Valve controls the rinse water to a Jabsco electric toilet. It stays closed until the toilet's flush circuit energizes it, so water cannot siphon into the bowl when the toilet is not in use. It fits Jabsco 37045, 37055, and 37075 series toilets. It is an inline, normally closed valve with a 1/2-inch JG Speedfit or 1/2-inch hose barb inlet and a 3/4-inch hose barb outlet.

On boats where the toilet bowl sits below the waterline, siphoning is a serious risk, since water can slowly flood the bowl and eventually the boat. A normally closed valve adds protection by staying shut whenever the toilet is not flushing. A failing valve can also explain a bowl that slowly fills on its own.

Wire it to the toilet's control and follow the Jabsco plumbing diagram for your model. Mount it where the filter and connections are easy to reach for service, and test the toilet after installing. The 24V version is listed separately in our marine toilets and sanitation systems.
