Black and gray tank sensors
« on: March 10, 2023, 06:43:40 pm »
I owned Winnebago Navions for eight years and both were bought used and both black and gray sensors never really worked. Last month I bought a used 2022 2552 and the sensors worked when I bought it but quickly stopped working. Folks where I bought it said if I flush gray and black tanks the sensors would work again. Tried that. Nope…Sometimes I wonder if ANYONE’s black and gray tank sensors work in the real RV world??

All sensors work (tho not terribly accurately) in our 2007 2350 (85,000 miles). But from what I read online, it is not at all unusual for them to NOT work in the RV world. There are solutions I've seen (maybe even somewhere on this forum), but I think the best one is to install new improved sensors and start from scratch.

I am tires of the four light system we currently have and am having installed SeeLevel system. It only make sense to me. Having it installed as we are also having other work done at the factory and while there why not. Here's a link: https://www.garnetinstruments.com/selection-tool/
Jack is what we call our PC 2351D, and he has taken us from campers to RV'ers and loving it. We're no longer Team Bob. Just Jack the RV!

Has anyone installed the See Level system themselves rather than having the PC factory replace the existing tank monitor system?  If you have please provide details on how you installed and connected the wiring.   Thanks

The usual solution suggested for erratic tank sensors is to clean the tanks annually or so with a bleach solution.  Several forum comments over the years maintain that keeping them cleaner improves reliability.  As flei states, replacing the standard "button type sensors" has been reported to be a more permanent solution.  Take a look at this string of eight postings from three years ago where Lance replaced his button sensors in his 2552 with the "Horst Miracle Probes"--he includes a link to a video of how to remove the sensors, and followed up a year later to report that the Horst Probes were working great:

DKCruzer--if you look at the above message string, you will also see a posting from WillLloyd where he reports that he installed the See Level system in his PC and that it was easy to install and used the existing wiring.

I had the SeeLevel II system installed by Phoenix when they built my 2019 2552, and haven't regretted it.  It's been a reliable system so far and I have gotten used to knowing where my tank levels are at all times within a couple of percent.

Both sets of 4 black and 4 gray  Horst Miracle Probe sensors are only ~  $60 delivered together  from Recpro.

The oem holding  tank suppliers should just make those standard. It really is ridiculous that they all still use the same old unreliable $3 sensors.

But if RVs came standard with the $60 sensors the manufacturers would have to charge buyers something like $6000 more for a rig.  pyho

I would waste ZERO time on the bullet sensor systems.  The See Level system works great and is an affordable and relatively simple install.
