Thetford cassette ...and petrol indicator

[PG’s trips]

When my petrol light comes on I usually have about 30 miles of leeway left before totally empty. When the Thetford cassette toilet red indicator comes on in the middle of the night tinkel does it have any safety leeway like a petrol engine ie I can put in another litre or so before it's really full!! I'm in France at the mo and too lazy to walk to the facilities. Such dilemmas in life

 

[David and Sally]

Depends on your actual cassette. Try it with water sometime.

Open the top of the loo peek inside and see how close to the top the mess is, and as Clint Eastwood would say…Do you feel lucky…Well do you

 

[Gellyneck]

Two points really, you shouldn't be running the fuel down to nearly empty as all the crud in the bottom of the tank could get pulled up into the engine and yes you do get some l(p)eeway in the cassette but this depends on which cassette.

If light goes on in middle of night we always have enough space left till morning....
Even if overfilled it is designed to empty without making a mess...
Open out side door.. pull emptying spout out.. place receptacle under spout and carefully remove spout cap and drain overflow into receptacle.... you will the be able to put cap back on and remove cassette..

Don’t rely on the light, just look at the level when the blade is open.

and, just in case, don't do it with crocks or sandals on!

 

[scotjimland]

when close to full..... use a stick .. or someones else's toothbrush

Dipstick. No not you, I meant use one!

But But But this pickup pipe is at the bottom of the tank should there be any crud it will also be at the bottom where the pick up pipe is and why fuel filters exist . Don’t shoot me for saying this I’m only the piano player

An old wives tale, the fuel pickup is at the bottom of the fuel tank, so why would it only pickup crud from the bottom of the tank when the fuel is low and not when the tank is full ?

Warning! Do not shake cassette too hard when washing out, I did and gained a rattle that was the detached, broken sensor. Getting a replacement not easy, fitting even less easy. So we live life on the edge with no red light. Ok so far.

but the crud at the bottom of the tank tends to get shook up more when it's nearly empty rather than full so it's in suspension rather than lying on the bottom.

Overflowing the toilet bowl tends to give a clear indication!

So fuel at the bottom of a full fuel tank does not move around in your view.

Of course it does but try shaking a full glass with a different coloured liquid in the bottom vs a nearly empty one and see what happens.

Run mine down to 1.2L once trying to reach the land of cheaper fuel (Luxembourg) it was nippy bum time, Mrs Westy chewed all her false nails off
Put 88.8L in and the light was on for well over 60 miles

My business was restoring classic cars and have opened up many a fuel tank for repairs, and the tanks from cars that were in regular use were as clean as a whistle and the only tanks with crud in them were the ones that had stood used for a few years and corrosion had set in, and with plastic tanks that are the norm now, there is even less chance, as I said, an old wifes tale.

Fair enough but I wouldn't be doing it again having had to get work done on a Saab 9000 after it was down to 29 miles on the clock on the M74.
Each to their own.

I empty my cassette when the contents are around 2 inches from the blade, I've never waited until the light came on.

[meanders]

Even if the tank corrosion did allow crud to form in significant density, it would be trapped by the fuel filter(s). OK. you might end up with slightly less fuel flow or, at worst case, a blocked filter but it should get nowhere near engine. As said, the fuel pickup is very near the bottom of the tank anyway

 

[Bobby-gg]

I've played toilet roulette once at a festival, it was touch and go wether the last use would be above the blade or not!

Never again

Once you've been parked up for a few hours any crud will have settled to the bottom of the tank anyway so no difference.

 

[hja]

We have two lights, one when half (?) full and another when full. Try and empty after first light.

Yes... Generally much easier to empty in daylight!

At that level on mine it weighs around 25 kg.

But when you are moving?
