Black Water Tank Gage

In time, you'll get "in-tune" with your camper and you'll know when it time to dump. You can always shine a flashlight down the toilet hole and see how full it is too when you "go".

But don't drop the flashlight!

never ever had a gauage that worked!

figure if fulltiming for 2 people about 2 weeks. remember when you dump to have the tank fairly full to help the waste go out.

Ignore it, use a water flushing wand though the toilet opening, water/ice combo, or if your patient you can put septic tank cleaner in a wait a week or so. It's a common problem - usually associated with hanging toilet paper/crude on sensors.

So the couple bags of ice has worked for me on difficult cleans. I will dump about 15 gallons of cold clean water in the Black Tank, Then just before heading down the through in about 20# of ice.

People will say this doesn't work, But you need enough H2O to for the ice to float and slosh.

Better to have a good built in flusher/rinser.

If they are working properly, that's not normal and warrants investigation... :)

Try spending more time flushing/cleaning the tank when you dump - with built-in tank flusher, wand or backflush elbow or a combination thereof. We have a built-in flusher and I let it run 10-15 minutes while packing up to head off and the tank bottom looks like new afterwards. Not perfect but reads much better. You can buy a retrofit built-in flusher but needs access to the tanks (no underbelly material or re&re it). You need to flush the crud off the "button" level sensors as best you can otherwise the readings won't be right. It may help to periodically use something to clean the black tank - geomethod, commercial RV tank chemical or in the worst of cases Liquid Drano (our owner's manual says to use it and have a couple of times).

In some cases the factory installs the button sensors at the wrong heights (hard to imagine, haha) and you are SOL from the start. If you can get to the tanks, check the mounting heights.

There is a retrofit sensor called Horst Miracle probes that can help sometimes. Installed them in a previous TT with excellent results but in our current TT didn't help much.

Tanks come in many shapes and sizes with outlets in many locations as well. Some are easy to flush and clean and some aren't. We've had both and now have the worst of them... :(

The ultimate fix is sensors that mount on the exterior of tanks like SeeLevel. It's too bad 99% of RV manufacturers continue to use sensors that don't work worth a carp. Many RV-ers just use their sixth sense or wait until the tank won't accept anything more.

I use the sensor to let me know when my black tank is clean - enough. When it finally shows empty during my rinsing process, I'm done with the job - til next time. :)

My gauges work. I use a wand through the toilet. No reason for them not to work.

Yep it like complaining about the weather, doesn't help! You can try ice and other methods listed herein, but it will be a fight you will not win!

I don't use the Calgon because it is sometimes hard to find. I use some cheap stuff that I find in Winco.
