Pump out Toilets

[SandyD]

I hope this is not a silly question but (assuming there is no electronic indicator) how do you know when a pump out toilet is full? I have hunted on the internet, and here and not found anything yet,

 

TIA

Without an indicator its probably not going to be too pretty!  I would guess that when you flush it starts to come back??

If it’s a dump-through you can tell by shining a torch down the hole when you flush, assuming you’ve been pumping it out properly and not allowed the old “pyramid of poo” to accrue beneath the valve of course

Often it’s the list of the boat, that will give an indication. 
A full tank weighs a lot, and is often fitted to one side of the boat, hence if the boat is ballasted level with an empty tank, the list develops as the tank fills.

Ours is a drop-through - so I made a graduated stick to measure the contents (also used to dispersethe contents ro aid aeration.

If the OP's  tank is remote - usually under the bed then taping the tank should give an aproxinmation of the height of the contents.....

Thanks All,

 

I think it is a drop through - so I will get a torch with a lanyard!

If it is a whitish plastic tank a bright torch held against a corner side can be moved up & down to find the approx level

A new take on the old game of Poo Sticks! 😀

The lesser known variant where you lift the glass out of the bathroom window, broddle the dump through with a stick, then (after knocking the thick off) launch said stick through the window and into the hedgerow. Furthest into hedge wins, bonus points for ricochet off jogger/cyclist/dog walker?

You dip the stick into the shit and then presumably have to wipe it clean and store the stick somewhere? Blimey, I thought pump out users thought cassettes weren't very pleasant....

My boat came  with a macerator pump out toilet which includes a "tank full" light on its control panel.

 

I was worried about what might happen if the bulb failed, so installed an MCS waste tank gauge, which fits through a hole drilled into the top of the waste tank.

The gauge soon paid for itself, as it showed that the "tank full" light came on when the tank was 50% full.

Mine has a little dial (that uses 12V) beside the lavvy pan that shows the level.

Reminds me of a speedometer. A peed-ometer?
