Holding tank sensor

does anyone know how to remove this cap?  I believe it is the sensor to the holding tank. It isn't working and I would like to try and clean it to see if a i can get a reading on it.

    From the looks of it its threaded on. Have you tried that?

    Right, just unplug the cable and unscrew the sensor. You can probably revive it by cleaning it.  If not, I think they cost around $80.  

    Suggestion: if you have a pump-out facility that will let you hang out for a few minutes, do this: pump out, remove sensor, spray inside of tank with a hose, pump out again.

    Is that the fresh water tank?

    If you need to replace it, I would suggest a Wema sender. I have one for my fuel and another one for my waste tank level as well

    thanks everyone for the helpful information.  My husband (CAPTAIN) tried to unscrew it but it is so tight i was afraid he would break it. <span>:smiley:</span> A good captain always adheres to the ADMIRAL, right?  :)   I knew i could take a pic and ask here. We do have a pump-out facility and will follow your suggestions.  thanks again.

    Most of the senders I have encountered are part of the actual assembly and not able to unplugged. After zooming in that looks to be the case as well
