Sensors apparently need cleaning because readout shows3/4 full or occassionlly1/2 full, when I know it is as empty as can be. Can you recommend one product that willclean the sensors? Thank you

Some folks throw in a bag of ice and drive around, others, have black tank sprayers (either built in or use a wand through the toilet.) Still others just accept that they are inaccurate and forget about it.I have used dynamite with good success.

Do you have one of those wands that you put down the toilet drain pipe? I use one about every second or third time I dump and my sensors stay clean. I have a "swivel stick" that has a brass nozzle that spins around and sprays everywhere. They have one with a flex hose on it for toilets that aren't mounted right on top of the black tank. They also sell a cheaper one that just has one fixed spray jet that you presumable twist all around inside the hole to clean all the sides and wash everything down. Finally, the tornado rinser seems like a good product. I bought one but haven't installed it yet. It's the same concept as the swivel stick but permanently mounted in the tank. The advantage is you don't have to drag a hose through the camper to use it. It has a piece of hose that mounts to a bracket and you just hook the water up to it right there on the outside of the camper. The down side is you can't twist it all around since it's mounted in the tank.The other solution is to put several bags of ice down the toilet and drive it on a twisty bumpy road. The ice should slosh around and scrub the tank. Then use a rinser either every time you dump or maybe every other time to keep it clean.Swivel Stick like mine but with a flexible extensionTornado Rinser that you have to mount in the tank.Cool video testing tank mounted rinsers by The Fit RV

Some European rigs have a round hatch at the top. This would be nice for cleaning out a black water tank... worst case, get a good pair of elbow-length gloves, a scraper and a wet/dry vac, which should take care of almost anything.

I gave up on those sensor. Strange as it may seem, our BT will go about two weeks from empty (like clockwork) before needing to be emptied with DW and I on board. I start to look and hear when that times coming. After dumping I mark the date on a calendar.

Before we had the Sanicom system with the built in tank sprayers I just added to the empty tank a quarter cup of Cheer and a half cup of water softener and then filled it up with fresh water. Then, drove around town stop and go for a few miles, let it set a couple of days, dumped, ran it full of clear water and flushed it out again. The sensors then seemed to work pretty well for quite a while.

This is an older topic - but an update on the Horst Sensors - Valterra has purchased the company and will be re-introducing those sensors under their brand soon.

I've wanted to buy and install the Horst Miracle Probes, but haven't pulled the trigger yet. I'd love to hear some first-hand feedback from anyone who has them.

We installed them on our TT and we liked them very much for the 6 or so months we owned the TT before trading it in for our Winnie with the stock TrueLevel sensors. So I can't speak to longevity with it, but they sure seemed to do the trick for the time we had them. If we were to buy a new camper without TrueLevel I'd install the Horst again...it would be super ideal to install them on a brand new tank before use if you catch my drift...but anyone who has dumped tanks or changed diapers or picked up after their dogs should be able to stomach the job on a used but empty tank.

I posted about it on our TT blog, though I don't know if I said much more than I said here :) http://visaadventures.blogspot.com/2013/01/poopy-talk-macerator-and-tank-probes.html

I also do not have a tank cleaner but use a wand. The cons of the wand are you have to drag it through your rv (I clean it with Clorox wipes) but the pros is you can move it up and down and get the entire tank.

Nope. I don't have a built-in tank cleaner, which is a big part of the reason why I have the wand.

We have the typical simple design tank sensors in our 8 year old motor home and they still work well. I can't say if this is the reason but I bleach the tanks at the end of the RVing season to control sewer gas because the rig is parked indoors under our master bedroom as shown here.

Had two Tornados break and leak and had questionable effectiveness. Now have Nofuss Flush with custom spray pattern to direct water at the sensors and back of tank. OEM sensors are now working like new.

Gave up on the sensors. Installed a SeeLevel system a few years ago. So far they have worked well. When Stuff collects on sensor walls. A short flush with Tornado Tank Washer and all is back to normal.
