Replacing the valve in a Thetford C260 toilet 

Glad it was useful!

Glad it was useful :)

Glad you enjoyed it. The hardest part was separating the inlet hose from the old valve. The rest is straightforward. :)

Glad it was helpful!

Good luck. :)

Kein Problem. Ich hoffe, es war hilfreich

@@howtodostuffchannel No, unfortunately not. couldn't find the valve. there was a note that my cassette toilet has no valve because there is a separate tank. Too bad the error must be somewhere else.

Sorry to hear that. If there is a separate tank then it's likely there is a pump inside/attached to the tank. What's the symptom? Is it leaking or just not working? (If its not working then could be electrical (switch) or the pump itself). (my system works from the main water supply in the caravan so uses a valve so Im not familiar with the other type. Perhaps someone else on here knows more?)

@@howtodostuffchannel I have already installed a new pump. But the flushing water only runs in a small amount and does not stop even though the pump is not activated.

Glad it helped. Good tip also :)

Hi, glad it was helpful. It's entirely possible that you can get away with only removing the outer bracket (if I understand you correctly). The main bits you need to get at are those clips inside that hold the bowl in place. If you are going to do the job then please share on here if the bowl indeed comes off without removing the rear bracket. :)

@@howtodostuffchannel Finally got around to looking at my one and it does indeed come apart as per your video. The problem was not the valve itself but the outlet side of the pipe had come off! I notice however that the outlet side and the pipes connected to the non-return valve do not have pipe clips. (on your video it also doesn't look like you have clips either) I purchased a new non-return (vacuum) valve and this came with pipe clips (also came with instructions which match your video, so I guess there must be slightly different models depending on age) So I'm wondering if there ought to be pipe clips or is there a specific reason why there shouldn't be? (I wondered if perhaps it was designed to come apart as a protection during freezing say?)

Interesting question...but I don't know the answer. Logically, if your pipe had fallen off and the new part came with pipe clips then they are probably needed.:)

@@howtodostuffchannel I have now fitted clips to all the connections. Although the main valve was ok I noticed a photo of the spare part showed it with two clips so it does look as though it should have them. Also what I though was strange is the the valve is essentially 'hanging' there inside the bowl with no support! Anyway, thank you so much for taking the time and trouble to put this video on RU-vid, I wouldn't have a had clue where to start without it

If this is one with a separate tank then this is what would happen if the tank is empty?

@@howtodostuffchannel I think I found the problem. Electric valve exploded. Will fix it in two weeks and I hope it helps. Males sense now why the pump keeps going and no water coming out. Thanks man :)
