Waste tank calibration manometer pics

Back in 2010, we had an issue with tank calibration and had to redo it ourselves.  We happened to be at MOT when we found the problem and asked a couple of questions about the procedure. 

As part of the explanation (and other help we got), Mike Rodgers loaned us the use of their "high tech" grey/black tank calibration tool.  This homemade manometer uses a sewer connection and garden hose to add water to the tank and has clear plastic tubing to read the height of the water in the tanks.  To get full status, all you do is watch the vertical clear tubing until the water reaches a height appropriate with being near the top of the tank.  The PVC pipe appears to be just for support of the clear tubing.

I don't have the exact dimensions (perhaps someone who visits MOT could make some "engineering drawings" of the device), but it looks pretty straightforward to build.

That's what I use to measure the water in the fresh water tank. When I fill it I sit out there and WATCH the level rise. I promised myself I would not overflow THAT tank again!

This would probably not work for the black water tank. Something or another might plug the previously clear tubing.... ;o)

best, paul

Used after extended rinsing of the black tank first, of course.  I would think if it didn't work for the waste tanks, MOT wouldn't be using it for the waste tank calibrations they do  ;)
