Toilet rinse

I’ve just drained & cleaned my waste & fresh water tanks, I was thinking of cleaning my toilet flush tank as well but is the only way of draining it is by pressing the button?.

The sight glass you can tell the fluid volume with, unplugs from a rubber bung on the top and then the flexy bit at the bottom allows it to bend downwards, this will drain the tank.

Don't do it on grass, it killed mine.

If its a swivel bowl, then it's unlikely  to have the sight glass Ian mentions,  so yes the only way is to keep flushing until its empty.

Interesting, never had a swivel bowl so didn't know. So, with a swivel bowl how do you know the tank contents??

You have a filling "door" on outside above the cassette door, you fill to base of the filling door.

Thanks Paul, if I ever get one I'll know where to look!!

And my swivel base one has a black rubber bung at the bottom left that you can remove for draining. The problem is that unless you place a small bowl in position very carefully the contents drain onto the base of the cassette compartment and who knows where from there. Some folks here have managed to replace the bung with a tap from a catheter bag, but I never managed to get a decent seal on that. 🥺

I had a swivel bowl in a caravan, There was a flexible drain tube on the side of the cassette housing chamber.  Keith

Yes I have a swivel bowl, think I will just press the button o drain.
Thanks

we make up a chute from folded baking foil, which we hold under the drain plug to direct the water out of the van.

Thanks for the idea, I've never been able to figure out why such a bad design was ever produced.   
Ours is a swivel bowl with manual flush operation, takes forever to drain tank through the bowl.

I keep meaning to make up an extension hose with a tap on the end but it's one of those low priority jobs I never get around to.

Neat tap that, can think of a lot of uses...thanks

Well I used the button & to be honest it didn’t take long to do a couple tank flushes.
Ready now for new season
