How is this Possible (Tank level question)

Full  freshwater at MOT.  Now Wednesday with no hookups.  Freshwater down less than gray water.

These gauges are very often inaccurate.  We lived with it for a year and put in a SeeLevel system.  Much better.

After Clide cleaned the sensors, MOT talked me out of the SeaLevel but would be happy to install if I really wanted one, which I did, but the cleaned and functioning contacts were good

As for Randy, he may find that the contact at one level works but not another.  So you might not read half full, though it is, and it only shows a reading again when more or less full.....I had that, one sensor failed.

Then you could get to some other ideas......try filling to top, see if get full reading.  I suppose are using pump, so getting water or has gone to empty, i.e. a leak.

OR, you just used it all up so gray is now more full because you took very long baths?  Or did you use shore water, which did not impact the fresh tank, but it got counted in the gray tank and so it climbed?  Hmmm

Michael, curious as to why MOT talked you out of Sealevel? They have worked well for me.

A couple years ago I suggested that everyone should test their gauges and senders by, first, make sure each tank is empty and then, second, fill each tank while watching the gauges until full is reached. Any error should show up.
Easiest way to check your system.

Mine are really not accurate, when my fresh water starts to move off of full it's about 3/4 of a tank.

Same here............. OEM gauges just aren't that accurate on our GV.  :headwall:

Jeff, just due to expense.

Randy, i wonder if gray and fresh levels by gauges are just due to volume differnces in tanks?  I feel kina silly asking that....i forget the relative volumes those tanks.

When filling my water tank one can watch the gauge moving back and forth as the tank fills. So in the beginning when I thought the fresh water tank was full; in realty it was not full. The gauge would say full but if one continued watching it, it would move off of full.

In addition to all the prior comments, (and like Mike just surmised) your fresh and gray tanks are probably not the same size?  1/2 empty fresh tank does not necessarily equal 1/2 full gray tank.

PS:  Don't you guys ever use the toilet?

PSS:  Disregard my comment on tank size.  Mike (below) checked - almost the same size.  Please go back to what you were doing.

Think I was guessing wrongly......gray and fresh water tanks very close same size, just checked on a 2000

sorry to belabor this and repeat others have said....but to reiterate, I got to where one tank would just skip registering the half-full mark.  It either was 1/4 or 3/4, so a time delay in actual volumes, just never noted 1/2.  that was fixed when the sensor contacts were cleaned, easily.

How it doing today, Randy?

I currently do not use gauges.  I can visually check fresh water in the bay by color differentiation.  I fill the fresh water to a couple of inches above the metal bar.  The tanks are within a few gallons of each other ergo if I need fresh water I am close to grey tank needing to be dumped.  Black tank adds gallons as well and we know that tank is a weekly.  I am considering see level but low on the list.  So I plan on once a week and check propane at the same time.

Example--only for our 1989 GV:
LP (only allowed 44 gal on 50 gal tank)
Fuel diesel 100 gallons
Fresh water  88 gallons
Grey  water 44 gallons
Black water  44 gallons
(got these figures from James Holder, Service Mgr at Tennessee RV. He has a 1984 GV)

Same here Dan, easy to check any time without having to have anything on the dash turned on.  It uses almost no power to be available anytime.  Having the display in the wet bay is very handy as well.  Best way to do this is to buy two kits.  You need extra strips anyway for the tall FT tanks and two kits are usually no more expensive than one kit plus extra strips.

Randy, Pretty easy project to do yourself.  I hope your trip is going well.
