Horst Miracle Probes for Wastewater Tanks in Recreational Vehicles RVs

I have a set of these, won them at the Hershey RV Show but haven't had the time to install them. I believe Herk7769 has a step by step installation posted on here as well. These are highly recommended by Gary Bunser [The RV Doctor].

Have been in the same club for years, but actually not so much. The grey are normally pretty accurate, the black never reads below 1/3 but above that is pretty accurate. We clean the grey tank (chemical through drain) about once a year. When the black start acting up I throw ice cubes in the toilet just before we pull out, by that evening travel I flush and then it is accurate back to the 1/3 reading. This has worked on all my rigs dating back to the 70's. I use the gages for when to dump.

I am in the "RV-Digesst it" club!! IT works for us! Clean tank/no stink!

Anyone use a dipstick?

If the toilet is straight into the black tank, you could just reach in with your arm...break up some of the solids while you're at it!

Ditto on the pee only, but the factory gauges still suck.

I had a Rockwood 8317ss travel trailer and now a Georgetown 350 and the sensors on both gray and black water worked fine. HOWEVER, I did have to learn a few things about them. First, I thought I was emptying the gray water all the way because the sound of water would stop after a while and I'd shut the valve. I could never get the gray water to read empty. I got a see-through connector and discovered that after about a minute all the air had been filled with water in the drain tube and the emptying process was silent, but water was still flowing. I now let it run until I SEE no more water and it reads empty every time.

In the travel trailer I would get readings above empty and I found if I flushed the system several times it would eventually read empty. With the Georgetown, it has the built in flushing system so I just flush it for a few minutes when I empty and get an empty reading every time.

Maybe I've just been very, very lucky.....

Yeah, stock gauges crappy many alternatives in after market to include see-level system

Hey f1100turbo, he could just let his grey water drain on the ground. Oh please, I hope we can get that going again! That went 18 fun pages!
