Thanks switz. I did a similar process. Carefully measured from the sink tap into a stopped sink up to 5 gallons, then marked and pulled the plug. The level helped for faster fill in subsequent cycles. Measured similarly into toilet but that was tedious. Now that I know the bathroom sink drains into blank tank I can take a faster approach. Assuming my dealer adjusts the sensors next week I'll go though this 1 more time to check his work.

This is very interesting and what we have suspected now having full-timed in our Classic since the beginning of February. The times we've haven't had full hookups for days at a time in one spot, we've taken big conservation steps with our gray tank (shower in bathhouse only, catch kitchen sink water in tub that we dump outside) so that only incidental water goes down, and we've been amazed at how our gray tank percentage increases.

We've suspected that at 100%, we still have a lot of gray tank capacity. One of these days when on full hookups, we'll ignore the indicator and keep going until the shower doesn't drain anymore and that should give us a good idea at how much longer we can go in spite of the 100% indicator.

Yes, very common theme and apparently something that can be resolved by physically moving the sensors (hard part is getting access). I'm taking it to the dealer next week - I have a 10-item defect punch list to get addressed. I'll update the thread when I get the unit back.

Preparing for this weekend, I did just now again try and fill my Fresh tank and was overflowing again at 45 gallons. I tried tilting the tongue up and still couldn't add more. Tried tongue down with same result. Hopefully the dealer will solve this mystery as well.

My Seelevel 11.
I've noticed that my grey reads 100%, and nowhere close to overfilling into the shower.
I can get three showers/days into the grey @ 100%, but maybe 1/2 shower or 3 day load of dish wash to overfull.
This is daily, no conservation, living in a stick house style of use.
Black tank, up to two weeks.
Fresh tank, it starts sucking air @ 10%, leveled rig.
I looked into my manual, no way to recalibrate, need to relocate the sensors.
"Chip Tank" is in Vacaville Ca..

Several have mentioned needing to move the sensor to re-calibrate. Perhaps just semantics but I thought that the sensor strip was a one shot deal when installing. That it could not be removed and re-positioned once applied and that a new one would need to be installed.

If true, something to keep in mind if doing it yourself.

What a shame, all the posts about the issues with the Micropulse system and then Airstream announces using the SeeLevel system and it doesn't meet expectations due to improper installation.

The several forum members who have retrofitted a SeeLevel systems themselves report better results.

I converted my Micropulse tank monitoring system to Seelevel last summer. A DIY project. The Seelevel is 1,000 times better. However one must have realistic expectations. The water tanks are flat and wide. Mine, for a 27FB, are approximately 5 feet long, by 2 feet wide by about 10 inches high. The sender unit is a strip of plastic with embedded electronics that is glued to the outside of the tank. So it's easy to see how just a slight out of level situation will cause a different read.

Since I did the job myself I filled both grey and black tanks to level I considered full then using masking tape place the sender's to read 100% at that point. Did the same for fresh, except to read zero when about empty. Do to the design of the Seelevel sender's they can't go exactly proportional to water level. In other words my gray will read zero for awhile even if say 10% full. However they will increment up to 100%, then the tank is full. Same, but opposite for the fresh.

The glue on the sender's is really sticky. I doubt they can be move without destroying them. The installations says so too. It's a one time stick on. Replacement sender's cost $50. However the really hard part is getting access to the tanks. I found that 90% of the cost of my project was labor. All in all though I'm very pleased with the SeeLevel over the old highly inaccurate Micropulse.

Our 2015 23' FC FB has also exhibited tank monitor issues. I too have added water with a bucket and confirmed irregularities. Looks like a trip to the dealer while still under warranty. Gray water is our biggest unknown at this point although fresh and black have issues. I fill fresh to overflow, carry a few extra gallons in the truck when boondocking, and monitor the black through the "loo" beginning five or six days into the trip to the outback.
