So the day finally came when I decided that I should really fit the new Thetford toilet bowl that I bought about 3 months ago. I was a tad scared of the job I’ll be honest, but also I’ve had very little time to devote to it, being told from a few sources that it’s a half day job and a nasty job too. The first thing I can tell you is that that is bollox. Even taking my time it was about 2 hours and that included cleaning the cassette and having a tea break.
Anyway, you can get most of the way by watching this video. It’s not my toilet mine is the C200CW, this video is how to replace the pump in a more modern toilet. However, the basic steps to get the bowl off are the same so I found it really useful for the main part.
I cleaned the compartment thoroughly, then detached the two front and back brackets, the front one being the one that holds the magnet. I’ve no idea what that magnet is for. Then there’s 3 brackets that actually hold the bowl onto the base but allowing it to swivel. Those 3 are all identical so no need to remember where each one came from. So, five parts, each with 2 screws, simple enough. The bowl is now free and you need to detach the flush pipe to actually take the bowl out.
Once the bowl is detached from the base though the pipe from the flush prevents you taking it off. It took me the use of a torch and dentists mirror to establish how to get that off.
This series of photos shows how. As you can see in this photo the flush spout is free of the bowl itself, and it wasn’t easy. There are 2 parts arrowed. The left part is sort of hooked in the hole that it goes through, retaining it when the right bit is pushed into place.
The right bit is a sort of spring clip. It’s actually underneath when you look at it in place, so you need to use a mirror to find out where it’s edge is, then I used a stubby flathead to prise that clip toward the body of the spout, which frees it from the housing. You can’t see what you’re doing so you have to see it with the mirror so you understand how it fits in, then simply feel your way while using the stubby. (Or whatever you use to prise it off).
Putting it back is the reverse and is a bitch to do with the pipe still attached. You hook the ridge shown left in the photo over the lip of the hole, then you have to force the spout down and in so that the clip at the right goes into place. I found this impossible to do with the pipe attached as the pipe is so rigid and large. So I took it off and put the spout in place and that was fairly simple to do with the pipe off.
I hit another snag putting the spout back in and the next photo show how I overcame that.
The pipe as I said is fairly rigid but as you can see in the photo, it has to come into the bowl, go around the back of the moulding and then attach to the spout. And therein lies the problem, it was almost impossible to get the pipe into place.
So, once again duct tape came to the rescue! I have some very strong stuff so I wrapped it around the end of the pipe, then fed the tape through behind the moulding, and pulled the pipe through using the tape. Once I had it in place I took the tape off and with one or two swear words I managed to get the pipe back onto the spout.
Job done! If I was to do it again I reckon it would take about an hour. I am massively chuffed with my new bowl, the first one in 15 years, and along with the cassette refresh my toilet is like new.
