Tank level monitors

[Stuart]

Hi Alanrd749 -

I think the tank sensors were just installed poorly (same as on our 2022 Beacon 39FBB). We always had inaccurate readings, especially with the black tank. Our model has two toilets with one being a macerator that has its own level sensors. The Spyder sensors and the toilet sensors never really matched.

Here’s a picture of the sensor placement on our black tank. You can see the difference between the two (Spyder and macerator). The Spyder display would indicate full when it was just over half.

I decided to add the See Level sensors that provide a more detailed and accurate level for the tanks. There are details in the post linked below.

See Level install questions

Thanks Ryan, that very helpful. I’ll be calling Spyder to also check on the update you mentioned. Still working on accessing the tanks by removing the coroplast which has turned into a multi day project. Those shot nails into the frame have gotten pretty rusty over the past few years and are a bear to remove. I have good access to the black and grey tanks now and just about the same for the fresh tank. I finally found out why our blank tank levels were not accurate and didn’t match the Thetfor…

I’d think that when they installed your sensors they placed them probably too low so they never read empty. Mine were a bit too high and too close together. That caused them to read empty when they weren’t and full when they were only partly half.

Picture below of our gray tanks with the sensors. The bottom sensor is high which would indicate empty even when it wasn’t.

You have a couple of options if you’ve had the tanks power cleaned (sounds like you did). You could drop the coroplast underbelly to get an actual view of the tank sensor placement. From there you could attempt to remove those sensors and if there’s not too much damage, relocate them so they are better positioned on the tank to reflect the 1/3, 2/3 & Full levels. If they can’t be re-used I think you should be able to replace them. The other option would be to go with the SeeLevel sensors described in the earlier post. They are much better and give more accurate readings (typically in 3-4% increments).

If you already have access by taking the underbelly down, that would be good time to upgrade to the SeeLevel sensors IMO.

Regarding the strong odor when flushing, be sure the vent fan is not on as that will suck the air & odors from the black tank when you flush (found that out by experience lol). We’ve tried lots of different tank treatments (Happy camper, Kleen tank recipe, the pods you can buy at Camping World or Walmart) but find that Liquified seems to do a pretty decent job.

Hope this helps!
