Can some one tell me how to check my tank gauges, My Black water tank always shows 3/4 full even after emptying. I have tried cleaning with different solutions but nothing seems to help. It looks like little screw into a rubber plug on the side of the tank with a wire on each one. Will these screws come out and can they be cleaned?
I had a problem with my tank guage sensors. I tried cleaning with a factory product with no results.
I then tried the ice cube method. Sence I have access to a ice machine this is not a problem. I put a medium size ice chest full of ice down my tank. To do this I usally have to wash to ice down into the tank which files it to about 1/3. I then add a small bottle of lemon sent bleach.
On my friends TT I saw some of the sealant applied around the screw that made its way onto the wire itself and affected the reading. I removed it, wirebrushed everything clean and reapplied sealant neatly. Problem fixed and he's happy.
Your case could be a different solution to the problem at hand.

You can buy devices which are lowered into the toilet, and sprays water along the side of the tank. You probably have a piece of toilet paper hung up on one of sensors. With these devices, you can shower down the inside walls, hopefully removing the culprit.

I, as well as probably every RVer in the world, has had, or still has the same problem. I found that there are two decent ways to remedy this, and they really do work, at least for me and others I have told about it.
For my tank treatment, I use a product called TST, available at Wal*Mart for about $5. It is a holding tank treatment that breaks down the waste, environmentally friendly, smells nice, lubes the valves, can be used in both black and gray tanks, and has a probe cleaner that really does work. It took me about the whole first bottle (about a month or so of camping) for it to fully clean the probes, but did a great job and now I can actually see what is really in my tank. Heck, my black tank showed FULL the day I pulled it off the dealers lot, brand new!
The other thing, crazy as it sounds, is this: fill your black tank about half full, then dump in about two bags of ice. Drive around for a while right afterwards before it melts. The ice banging against the probes will clean them off good as new. I've tried it and had great success with it. This would be a great thing to do initially, then with clean probes, use the TST to maintain the probes and valves. Hope this helped.

You can also pick up a toilet wand that sprays water under high pressure in your holding tank through your toilet. They are not expensive.
You just open the flush valve on the toilet and stick it down in the tank. Be careful though, you do not want to pull it up to far in the toilet while you are moving it around to flush the tank out. As it will spray back up on you. Not a pleasant thing to have happen.
I use on in mine about every two or three campouts. Especially if I have full hookups.
The sensor guages are not that accurate anyway.
Especially when things collect on them. They do give you a basic idea as to what the level is in the tanks when they are working.
The wand does help clean out any build up that may be accumulating at the botton of the tank as well on the sensors.

I got my 5er used and I had a problem with my tank guage sensors from the start. I tried cleaning with a factory product with no results.
I then tried the ice cube method. Sence I have access to a ice machine this is not a problem. I put a medium size ice chest full of ice down my tank. To do this I usally have to wash to ice down into the tank which files it to about 1/3 or. I then add a small bottle of lemon sent bleach. All this just before I pull out on a trip. when I get to first stop on the trip I dump the tank and then add my chemicls for use of the holding tank.
I've used this technique for the last two years and never had another sensor gauge problem.
