When the flush button is pressed water races around the top of the bowl, and apparently assisted by centrifugal force some of it escapes from the bowl. Although it is clean we end up with a wet floor.
I don't remember this being a problem until recently and I can't see any way of adjusting the pressure, volume or angle.
Has anyone else had this problem and found an answer?

Not much help probably i.t. but I don't use the flusher, instead I have a small bottle of water and do it that way, saves on water that way. I also wipe out the bowl with disinfectant wipes and throw them out in the rubbish.

Well that is certainly an option for us too.
Did you adopt this option because of the same problem or to save water?

To save water. I have limited water most of the time so every drop saved helps.

I use toilets wipes also, throw in the rubbish. Also very little water, I don't flush. By flushing you have to frequent the dump points a lot quicker than if you don't. Anything to make life easier.

Barry, we have the press button - whilst drepressed it flushes and stops when you take finger off button, so can use as little as needed, but sometimes we have the same problem as you. It usually splashes over the front - not very often though.
Ive done the same thing as you and that's feeling up under the lip of the top of the bowl for any adjustable water pipes - but no joy. I spoke our Dealers caravan shop. The Mngr there has been in the RV game for about 30 years and said this problem is quite common and Thetford has tried to fix the design, but without success. He said though, that often its caused when the RV is not level and so the water flows out quicker at its lowest point rather than equally all around. Since then, I've noticed that if it does "overflow" the van is not very level.
We have it happen maybe once in every 50 or so flushes, and not much splash, so we just wipe up this clean water marks with toilet paper and it goes in the rubbish bin

ours spills even when the van is on the carport slab. I don't know if it is worse when the van is not level. However it is some consolation to know we are not the only ones. Now it seems we are going to use the above "solutions".
Thanks all for your assistance.

Hi BJC
We find we have trouble if we don't bleed the air from the water lines as the air squirts the water. Also don't push on the toilet button hard, more of a half press. We find if we press hard on the button it splashes. Alternatively you could turn the tap down on your connection to the van.

only seem to have the problem when connected to mains pressure
I plug a gap at the LH back corner with a small wad of toilet paper as a temporary measure

I too have that splash problem occasionally.
As a temporary measure I use a small wad of toilet paper & often think about putting a dab of sikaflex on the edge of the bowl to break the water flow, but never do it.
I try to only briefly push the flush button but that doesn't work for SWMBO.
I'll put the problem on my 'Fix it' notice board in the van & then one slow day I might actually get to have a good look at it.

Has your van manufacturer fitter a pressure reducer as per the Thetford installation guide ?

If the van builder left the plastic bag of fittings that were 'surpless' when the toilet was fitted you should find a small piece of yellow or orange tube (can't remember exactly).
You will find this tube sleaves into the tube that carries the water to the bowl when flushed.
Easily installed you just cut the water feed tube and push each end over the small supplied tube.
When installed it acts as a reducer and still allows enough water for a successful flush but shouldn't allow enough pressure to overflow the lip of the bowl.

I thought there might have been an OEM option to address this problem but if any bag of bits ever existed they were gone before we got the van which is quite 2nd hand.
However I might try re-inventing this option. Any luck and I will start a new thread as there are obviously others with the problem. In the meantime it looks like the nice simple bottle of water answer. Thanks all.

Does your Van have a Pressure Regulating Valve fitted at the Mains Water Entry either the Shurflo Type or the Brass Plumbing Type as used in Household systems. Most are 350kpa-50psi rated units. If not then you could have TOO much Water Pressure. We have NEVER had a problem with our Thetford C200 Toilet flushing system, except as said before when AIR pockets need bleeding from water pipes/system.
Cheers Kev.

Our van had the pressure reduction valve fitted but we still had the toilet flush problem.

we're the same as Sparkster - and if they didn't fit all the bits when fitting out the van - they threw them in the bin. Ddidnt have any spare parts left when we bought the van.
We just press the button more carefully and not for too long - sort of short flushes till the business it done

mr glassie, the last few years they've changed to the flushing water being drawn from the main supply, either the on board tank or whatever you are drawing from.

Hi had the same problem solved it by putting a bead of acrylic gap filler on the rim of the toilet just under the seat.
Once it hardens you can clean the toilet rim without damaging the bead. No more water around the base of the toilet
Also have a solution to a smelly cassette/toilet C250/260 orange wheels on the cassette

Hi.Under first seat ring the second has a recess possibly for toddlers.I have used gaffa tape to prevent spills.
