Tank gauges seldom work correctly!

Get the See Level system and all those issues go away. Works well every time. Accurate, easy to install.

The guy next to me last winter had the SeaLevel system and when the black tank wall got bad enough it would quit indicating. The manual said that would happen if enough crud built up on the tank walls.
He hired a guy with a pressure washer/video camera system that went up through the dump valve to clean the tank. It worked after that for the rest of the winter.

Hear reference to the probes understand the problem there but my 08 has the outside sensors thought that was to do away with the problem of fowled probes.I suppose the problem is still coating builds up on the inside of the tank that prevents the sensors from reading level?I did find a reliable method on last MH DRILLED HOLE IN TOP OF BLACK WATER TANK AND MARKED LEVELS ON A 1/4"dowl and just put it thru the hole and always get correct reading.Only truly reliable system I have found but not convenient to do on my new MH can hardly find the holding tanks!!HAve you found one of the numerous chemicals sold at RV stores to work to remove the build up on the inside of the tank if that is really what is causing our problem??

Interestingly I read in the holding tank manual that just plain ole well water's will foul the sensors.

I periodically will pick up a bottle of thetford's sensor cleaners and add it to both tanks when I am filling them up with plain water after I dump. Let it sit for awhile. Then dump. Seems to fine tune them.

I have to say the grey and black sensors on my Itasca work perfectly and have for years. The only problem I have is on the fresh water tank, always says it's 2/3 full!!! I'm sure it's not because I always drain it down to 1/4 before rolling.. Any idea's on how that works...

I installed Hoarst (sp) probes on my black tank and love them they sell kits for all of the tanks and install was easy and straight forward. Also I started using Unique Digest it and when I dump its nothing but liquid. I also use the black tank flush after every dump. The just add 2oz of digest it and voila. They also claim that using this product will clean your sensors.

No longer in stock/available except maybe some old stock laying around at Amazon.

The old days they always told us the gauges didn't work reliably because the probes in the tank got dirty! Now whats there excuse with my new one with the external senders nothing internal but they still can't be trusted!!I suppose todays story is that build up on the inside of the tank prevents proper reading??The RV store has rows of costly chemicals but do any of them work!Maybe I am the only one with this problem? Any hints will be appreciated

What new RV and what sensors are being used?

My original in tank sensors work perfect as they have since new in 2001. The secret is to use an in tank flusher and use lots of water when you flush.

You can clean your tank with some water softener and dish soap. Read HERE for the how to.

All my tanks gauges are on the outside of the tanks and they don't work properly. When I want to know how much water is in my freshwater tank I lift the bed up and look down at the tank. For my black water, I hold the drain open and look down there with flashlight. For the grey; if water is backing up in the kitchen sink-time to dump!

I use the basic chemicals that have been around for eons for the use in RV and Marine vehicles. There is a reason these products are made and sold.:W They break down waste and paper so the big clumps don't stick to the sides and the sensors.



Every time I dump I fill it back up with water and dump again.
Just run water in the bathroom sink to fill the black tank. No need to drag a hose in.

Been doing it this way for years and MY gauges work ALL the time!
So YES it does matter how and what you put into the black tank.

You will hear everything from the magical GEO method which is a softener that does nothing more than coat the sensors to using nothing. And all of them will tell you gauges just don't work. :R
