Hi, my name is XXXXX XXXXX I have been in the plumbing and plumbing repair field for 20 years. I will be glad to help you today.
If you open the caps above the bolts there is a screw head there. The bolt is designed so that when you turn the screw the nut underneath will not turn.
Cannot get at screw head - top is just a chrome disc. I can turn it but that just turns the screw and the bolt together.
Are you replacing the seat or the toilet? Do you know the model or can you send a picture?
Just the seat. Toilet is 'Vitra'.
ok. Give me a minute so I can pull it up.
The chrome cover on top should come off. If you slide a knife edge under the edge of the cap it will pry off and expose the screw head.
I think I was looking at the wrong model.
Here is directions for removal of that model. http://www.gushbathrooms.com/uploads/products/Changing%20a%20Pluto%20seat.pdf
Thanks. Have had a look. Fittings not exactly the same, though similar. But nothing to help with getting the chrome disc off (it has a sort of hook attached - that's what the seat hole slides on to).
So they were the type that expand when tightened then. Did the new seat come with anchors?
New seat comes with everything to attach it - chrome disc has hole underneath for bolt to screw into. You then place bolt through the hole in the pan itself, put a couple of plastic washers and a plastic wing nut-type thing on other end, then tighten up the wing nut. Did our other toilet earlier today. So I just need to be able to free up the holes in this toilet, then bingo. Don't think I will get hooked chrome disc off. Think best bet is to apply something to loosen up the wingnut/washer - any suggestions?
Do you have a hacksaw blade? Might be easiest to just saw the end of the bolt off.
Maybe. It would be hard to get in at it.
If it is a bit loose maybe it would be easiest to slide the hacksaw blade under the bolt head and saw it off.
OK, that worked - eventually! Have now discovered the other one isn't as free as I'd thought, so will have to do that one same way! Thanks.
