How do you know when the Porta potti is full?

[The Shakeys]

Some of the Porta Potti models have a level gauge.

But the 145 and 165 do not. How on earth do you know when to empty them, you don't want tobwait until they are overflowing.

Any experience with non indicated models anyone?

Thanks

Hello and welcome, you've already made a splash here. If your getting splashed rather than making one, it's time to empty the box!!!

Hello and Am looking forward to this conundrum as the one in my day van has no indicator either. Am likely to empty it daily to be sure or last thing before leaving a site and first thing arriving at another if i do a bit of off site in between.

My one has a light, but it requires a battery and I have never bothered to put one in, I use bio tabs and empty it daily or if like yesterday we are leaving in the morning I will leave it an extra night, with 2 of us using it full time and flushing well, it can last 2 days but it rarely gets to do it
