Older style Thetford toilet cassette switch was not working and I discovered why and what the last owner had done, they couldn't be bothered to fix it. ru-vid.com...
Thanks, learned a lot. I have the same loo. Can you show me where the fuse is. I've had a new pump but now it's not flushing and can't afford a £50 callout charge again.
But why does it turning so late? It's like when it's almost full it starts going to red. Halfway red should mean halfway full? Maybe the magnet inside doesn't go up before it's very full because it's old?
All you've got to do is look down the hole to see if it's full. Also I clean the cassetts out with ct18 after each lot of camping. (So clean you could eat out of it)
That's what we were doing for the last few years, but I like to have things working, it was a simple fix and couldn't believe they just silicone over the indicator because they weren't bothered to fix it.
FOOLISH man showing himself up, the spring loaded vent is held down , allowing the tank to Vent to outside of the caravan, otherwise the fume will go into the caravan. The spring closes the valve on pulling the tank out to empty. A SIMPLE look when the tank is in place will show you this. I am 4 minutes into video, should I NOW LEAVE or suffer more???????????.
