Holding tank sensors

Ditto on SeeLeveL. I also tracked down a direct fit replacement gauge for the propane tank so my panel gives me levels on all holding tanks and the propane tank.

For what it's worth, I hit the tank with a pressure washer as far as I could reach into the toilet then used the sewer flusher again and, for now, the sensors are reading empty. Have ordered the Happy Camper organic "smell pretty" that was recommended in this thread and will start utilizing that once I receive it. thanks for all the input.

Horst Dynamics makes extra long probes that stick into the tank past the slime on the inside of the tank. I put a set in and so far they work. The slime conducts and these probe are supposed to eliminate this.

x2. Horst miracle probes, while not a complete miracle, do work FAR FAR better than the factory probes and for us have been accurate and troublefree after 3 years and close to 180+ camping days.


Not as troublefree as the sealevel, and you get the same resolution as the stock sensors (E, 1/3, 2/3, F) etc. but less expensive and easy and quick to install. Sea Level etc will give you more resolution.

quote=G and D]Well, here I come with another dumb question where the answer is obvious. I have found that in areas I am not yet familiar with I quite often make the wrong assumption. Sooo. In my 97 Gulf Stream Conquest there are two long tanks about 6" deep that rum from one side of the camper to the other. Im sure one is black and other is grey water.

Reading the posts it sounds like the problem with accurate readings on the tanks is caused by crud slime and subsequent corrosion. The products mentioned work to flush the yuck out and help the sensors get better readings.

My tanks on the end opposite to the dump valve each have a hose fitting. There doesn't appear to be any valve, they are just there so I assume (dangerous particularly with this application) that there must be a backflow valve. Is this fitting so I can attach a hose to the tanks and flush until clear? Would be cheaper than buying equipment I may not need and screwing on a hose is my kind of installation!

Thanks for the input

Any input on what the hose fittings are used for?

You can always look down your toilet with the flush valve open and a flashlight to see "actually and absolutely" how full your black tank is.

The grey tank will back-up into your shower floor when it's full. You can then easily off-load some grey water from it into your black tank to get by for awhile until you can empty your grey tank.

However, I keep our sensors accurate through regular use of this in the grey/black tanks after each emptying of them:

I've experimented with many tank additives to keep the sensors accurate, but this one above has worked out to be the most reliable on keeping the sensors working correctly.

I've found a big difference with regards to the chemical used in the tank, We always use AquaKem, with formaldehyde. And we never dump unless the tank is full.. never partial dumps as you want the sensors wet so that less sticks and it's more or less self cleaning.

Rarely do our guages read incorrectly.. and if they do, by the next dump, they're fine.

Horst Miracle Probes worked for me.

X 2, Mine have been 100% reliable for nearly 5 yrs now (and running) of mostly dry camp use. Quite honestly I would not be without them since they have likely saved many unnecessary trips to find a dump.

Our false readings ended when I installed "Tornado" tank rinsers in each tank. When I dump the tank and it doesn't read empty as it should I connect a hose to the rinser and in less than a minute it reads as it should.
