Holding Tank sending unit

[BobFino]

Hello, on my 2005 550 Sedan Bridge the holding tank is not reading correctly. I already flushed with clean water and a packet of tank buster. Still reading the same, so I am thinking sending unit. Of course it is located behind the generator and difficult at least for me to get to. Any thoughts on how to remove it, so maybe I crawl back there one less time? Picture was taken by reaching over generator. Thank you

It's not fun getting back there. Try tapping on the fitting with a rubber mallet and see if you can break the floats loose...

Or start using noflex and wait for it to clean the tank and sensors…

Hang a small chalkboard in the head. Have people log every time they pee and poop. At 20 pee and ten poop, empty holding tank. Erase chalkboard. Start over.

strict no #2 rule on this vessel. It’s a slippery slope to duckbill valve replacement.

Fill that tank 3/4 full with water add a bunch of tide powder and oxiclean. Go anchor in some chop for a few hours and let it work. I would give that a chance before tearing it apart. Oxi and tide will break down a lot of buildup, the sloshing will help

LOL. Thanks for all the suggestions, I really like the chalk board idea!!! I will give these a try before removing.

You guys that will not use the head to its fullest function crack me up.

I have never read a logical reason not to use it, most reasons are poor management. Using your duckbill replacement example, if that is a majorly disgusting job, maybe your using the wrong product in your system. With noflex my toilets look like new inside (they did not when I bought the boat) and do not stink.

Agree 100%. I have rebuilt both of my pumps including bellows, o-rings, and all duckbills. Very, very minimal smell and not a bad job at all. The toughest part was accessing everything. When we got the 420DA, none of the lights would work on the MDP as to how full the tank was. Continuous use of NoFlex and everything works. I thought they were gone forever and installed an analog sender and gauge by KUS. Now I have two functioning systems that tell me how full we are.
