Sensor Cleaner

My black tank goes to 3 bars on the meter after a flush of all liquid. A couple hours later it will read 1 bar. Even when the tank is empty it is possible for the sensor to simply get wet.

GEO Method: 50/50 mix of Calgon (Borax also seems to work) and original Dawn diswashing liquid. Many, many people swear by this. That, and always leaving a few gallons of water in the tank whenever possible.

What about general and incorrect statements that do not work from someone who has evidently never had "outside sensors"? What external system are you referring to?

I installed on our current trailer, and had on our previous two trailers, SeeLevel systems from Garnet Instruments. I have yet to have an issue with them not working or reading inaccurately.

EXACTLY what you provided a link to.

Grey valve is OPEN and look what the level shows, usually it's 13% when the valve is opened.

Mine have always read 0 with tanks empty / valves open.

In that case either the sending unit / strip was installed too low on the side of the tank, or the tanks hold residual fluid when the valve is open. Another thing that may cause that is the sending unit being installed too close to ferrous metal but thats hard to accomplish, especially on black and gray tanks that hang from spreaders.

The Seelevel system is problem free and close to perfect if the installation recommendations and instructions are followed. There is very little that can go wrong with it. You can't blame Seelevel for installer error.

Yea but Alpenlite/Western RV most likely did a good job of installation.

We have not had any issues with our outside tank sensors.

I've tried all sorts of things including dish soap, dishwasher soap, and a whole tub of Oxy clean.
The only thing that really worked was a wand down the toilet aimed at the sensors.
Nothing worked for the grey tank.
Most of us learn to ignore the tank sensors and just go by time and use.

Done all that too. Grey works but nothing helps the black. After dumping we put a few gallons of water into it to slosh around as we go down the road.

Gave up on the sensor. It goes to no lights or one light on emptying but after one 'deposit' it reads full again. We dump every 3-6 days. Whatever is convenient. Don't pay any attention to the lights. They are fullofit.

We use Calgon water softner right at the beginning of an outing. It does help by allowing things to slide a little better. Not perfect but with easier to rinse out in our opinion.
