Hi,

I'm hoping someone will be able to answer my question as it's starting to really bug me.  I have a Catalano Zero + toilet which has a loose seat.  I think it is a top fitting seat based on the internet research I've already done.  I can find lots of details about replacing such a seat, but none that seems specific to the Catalano Zero (I've checked the Catalano website but can't find any information there) and it's particular fixings.

I just can't figure out how to remove the seat/hinges, and I don't want to break the hinges by pulling the seat too much.  I've attached some photos of the seat fixings and hopefully someone can help.

Cheers

It does look like a chrome cap on the top of the chrome post.  A stanley blade or filling knife may help.

I suspect it tightens from below, so you might need to remove the toilet!!!  

Nope the chrome part will come off some how.

Hello,
i haveexactly the same loo seat and searching web as would like to replace it and unsure how to get it off.

Was wondering if you ever found a solution to removing the seat.

Any help granted.

I am convinced it has to be removed by loosening the chrome disc but it will not budge.

Thanks

I have exactly the same dilemma with exactly the same product.  Did any of these suggestions work or was any other solution found?
thanks in anticipation!

Thank you for your prompt response.
Yes, believe it or not it is exactly the same product and model, and exactly the same problem (although down here in Australia the water swirls the other way round of course).
I have tried all the suggestions made with no success. There is no access at all from below, the chrome pegs are one piece, and there is no spring loading.
I agree it should not be all that difficult, but it seems to be!  There is nothing on the Catalano website or their online technical sheets of assistance.
I will keep enquiring and post anything I come up with.
Thanks again

Delighted to report that I have figured it out. (The model is exactly as described and depicted in the very first post above - Catalano Zero+)


The tightening mechanism is by way of internal butterfly nut so there is no access to it except by lifting and turning each vertical silver peg clockwise.
This mechanism is explained and demonstrated here: https://www.youtube.com/watch?v=B3siBoPGPPg
"How to change a GSI top fixing toilet seat with butterfly clip"



Of course, to be able to turn the vertical silver peg you first need to disengage the horizontal silver peg, at the same time detaching the toilet seat and lid. How you get each horizontal peg out is not at all obvious.  It is not a capped grub screw (as suggested in the video), but just a silver cylinder which is held in place by a rubber ring sunk into its body about half way along. Unfortunately the ends of the horizontal pegs when installed are pretty well flush with the face of the vertical pegs, but with a bit of sideways manipulation you can get a couple of millimetres poking out.  That should be just enough to prise out the rest of the horizontal peg, first with a small screwdriver then using finger and thumb.  Once the horizontal pegs are out and the  seat and lid are set to one side, just lift each vertical peg in turn, tightening them clockwise as shown in the video.  Putting the small screwdriver through the horizontal hole gives enough leverage for good tightening (but don't overdo it and crack the unit).  Make sure the horizontal holes are lined up, then replace the seat and lid by pushing the horizontal pegs back through the holes into the seat and lid.

I hope this is clear.  Let me know if it isn't.

Thanks for the interest shown in this problem.

Perfectly clear Markcb.

It was the peg bit that gave it away.

Is there anyway you can actually push the pegs out by holding the seat in different positions.

Pssssst, we had a toilets seat delivered and there was 32 bits of plastic, all needed.
