When the blackwater is full

I also do the Sunday Dump, but if it gets full before Sunday it lets us know by it's burp.

I personally do a "Sunday Service" on both tanks.

Those gauge lights are...well...full of it. We dump. One light is on. Make one or two 'deposits' & four lights are on again. This after doing a procedure that puts a few gallons of water into the tank to slosh around after dumping.

We stopped getting frustrated by those stupid lights long ago. We simply do a minimum of three days between dumps & don't go more than seven.

If your a fulltimer do as we do and start with "BLACK TANK TUESDAYS".

They work, but I don't get much "resolution". 4 LED lights that indicate full are not that helpful when trying to determine if the tank is full - full.

Easy Peasy, when the third light lights up, dump the tanks. If the fourth light lights up, you are past due to dump.

Let the flush & burp tell sign be your guide!

You need to take a dump less often or dump your RV more often.

At least you're honest. We've stayed a week while dry camping and the first thing (fresh, gray, black) to limit out is the fresh water.

Most of them are notoriously incorrect anyways.

For me, the gauge is a guideline. Once it says it's 3/4 full, it's time to start considering emptying the tank. I don't need it to be exact - I don't push the capacity to the extent that it will mean overflowing.
