Thetford C224CW pump replacement

My thoughts are that it might be easier to wait until you get home to repair it as the pump might just be seized up. Meanwhile, you can flush the toilet by pouring water down it from an old milk bottle or similar. It’s not a big deal.

You need to speak to the warden re delivery to the site.

As TW said, happened to us while away and just use a jug or something. It was easily fixed by the dealer and was a seized pump.

The wardens might have details or a mobile caravan engineer if you can't wait? They usually do, or they'll be a leaflet in the information room? And they should let the engineer on site, again they usually do.

We have asked the site staff and they are happy for us to have it sent here.

But, does anyone know how you can remove the flush/pump part? There's no screws or anything obvious. Don't want to start trying to pry it off with a screwdriver and break it!

Nope, sorry, I’m not familiar with that toilet. Have you considered the option I stated?

If you really want to do it yourself have you tried a Google or YouTube search?

Thanks, we are doing that at the moment. But really we'd like to learn how these things come apart so we can fix them if necessary.

We have done lots of googling and can only find videos with the older model which has screws that ours doesn't seem to have. Even the Thetford site has a video with an older model. We've attached a diagram to this post. It looks from videos like it should just come out of the top, you disconnect the water hose, reconnect a new one to the water hose and put the new one in. But we can't see how to get it out as there are no screws. I might try calling Thetford tomorrow. It looks like a simple DIY job if we could work out how to get the old one out.

Sorry I can't help more, the wardens might. 

If it's any help on ours, which is electric, you get to the pump by pulling off the spongy plastic control panel.

Perhaps the circular bit rotates to lock into place. A pair of rubber gloves should provide enough grip to apply gentle pressure.

We have looked a bit more closely at a picture of it and it does look like it should just come out:

Probably using something like a screwdriver to wedge it out and being careful not to damage the container around it. I can't see any other way of getting it out, even for a service engineer. We are going to try descaling the tank with Puriclean first, A Thetford video suggests scale can stop it working properly. We have also emailed Three Shires Leisure who service it for us and are very helpful and might be able to advise. Think we will order one to be delivered to the River Breamish caravan club site tomorrow. If we need it great, if we get it out and can repair it, we have a spare for when the inevitable happens and it breaks!
