Have you tested the amount of volts going to the valve?
If it is not receiving the full 12 volts, that could be the issue.
Could also have trash inside the valve… you can open the valve and clean it
Not everyone has room for a manual valve or wants exposed hoses/ valves inside their vehicle… and yes you can still have problems with a manual valve.
Not draining your tanks every week, will lead to corrosion in the tanks and the valve. Open the valve and clean it up.
tank was new so no h2o.
i took it apart and cleaned anyway.
i think the time it stuck open was when car was not running, so maybe a voltage issue…
has not acted up since
voltage only opens the valve… then it gets no voltage the valve closes
