Having a lovely long weekend away at Heaven Farm in East Sussex. However, I cannot refill the toilet rinse/flush tank. The glass tube suggests that the tank is empty and the flush motor runs ok. When I try adding rinse solution to top up, it will not clear the aperture/arm into which it is added. This quickly fills up but just stays there. I am set up level and never had this issue before. I have searched the forum but not come up with anything. I am considering buying a pipe cleaner brush and gently pushing that through the aperture to try and clear any potential blockage. Before I do that, I wondered if anyone had come across this before and what the potential causes and solutions are?

I have a 2013 Triton 430

Many thanks for any thoughts and suggestions.

Am I correct in remembering that a 2013 model will have the swivel Thetford, not the bench type that came before and after?

The filler is still inside the cassette locker, like the bench type but the tank/cistern has to be around the cassette space and therefore you should be able to hear water dropping into it as you fill. I would think there's hardly anything to block up before the tank opens up inside.

Probably best to take a look at the exploded diagrams for that particular model on the Thetford website. It'll presumably be C250 something or other.

are you sure that there is not a problem with the site tube, take the bung out of the top and try blowing into the tube to see if there is a blockage, this happens with ours and it's a job that I need to rectify at some point.

It sounds like you’re not using the funnel!
The end of the filler tube is actually not low enough to allow flow. Haven’t you got a sort of green bottomless cup somewhere in the area?
This fits on the filler tube end thus increasing the height allowing proper filling.

Ah that’s what it’s for !! I never knew
We had a 2013 with a swivel loo but the flush was plumbed invto the main water supply, there was no separate flush tank
I would second Tony here with his suggestion of using the funnel

Hi everyone thank you for the replies and suggestions. I suspect the funnel is the long term answer. Cal (Conal) has very kindly sent me a picture of one. I see the logic of raising the water level on entry to the filling arm. I guess this is then enough to push it through to the “flush tank”. I will also consider the 50p funnel as worth trying. I seem to have got round the issue short term by gently pushing the blunt end of a fork into the opening on the filler “arm”. I felt something like a flap give way and suddenly the rinse solution was flowing into the tank.

In case you are wondering this is only our 2nd trip in this Eriba and must be first time I have needed to refill/top up the rinse water tank. Thius wasn’t an issue on my Familia or other units I have had with Thetford toilets.

Out of interest, do other owners empty the rinse tank at the end of a trip? I have not bothered in the past but I can see there is a case for doing so.

I empty mine the same way but always leave a little in the flush system for use in transit.

We're like Pepe - we have never thought of using the toilet in transit as we always stop at service stations. We always empty our flush tanks into the toilet before I do the final empty.

Also like many others I carefully look after the green thing but up until this feed have had no idea what it is for - it just looks too important to leave at home.

In defence of Johnf I think the instructions in the Eriba handbook about filling the flush are pretty iwoeful. I was worried at first about the filler not taking any more water and overflowing. Only by trial and error did I realise that it would take litres of water despite looking like it would overflow and second MikeT
