    Anyone know how the windshield sprayer on 45 express is plumbed?

    I was using today and the spray is stuck in the on position. Had to shut down water pressure pump to stop it

    I assume the momentary switch controls some sort of 24v solenoid of sorts.

    Did a quick look but will have to go back to the boat to do a more detailed survey. Had hoped it would be under the sink but didn’t see it in there.

    Any hints would be appreciated!

    Been a very long time since I spent much time on a 45' Express, but look in the area behind the electrical panel.

    Many builders use off-the-shelf valves like this:

    You can likely find the exact item through searching images:

    The valves are often mounted as close to the sprayers as possible, so the wipers don't run dry for too long when activated. Some cars use check valves to prevent leak-back for the same reason. Keep the water supply pipes full.

    Found it! Was able to trace the water tubing back and there is was right in front of me, ( well not really ), mounted on the starboard hull liner aft of the hot water heater. A little embarrassed at how long it took me to find it..

    even better, disassembled the valve and found that it was just a bit of debris that was causing the normally closed valve to not seat correctly.
    Cleaned it up and back in business.

    Might have taken some time but that's a win in my book. Thanks for sharing that info. I still need to find mine,
