Toilet coupling guidance rge plastic screws

[scoz]

Could you guys part some of your wisdom for me, my daughter has moved into a house and the toilet inlet float is just catching the side of the cistern and sometimes does not fill. The inlet is the type where the float runs up and down the inlet mechanism. If I need to uncouple the cistern from the pan there looks to be two large plastic screws in the bottom of the cistern, do these just unscrew leaving the nuts behind as I have never worked on this type before it has always been the steel screws straight through that I have worked on. Any info greatly appreciated.

Any chance of a few pics

And have you tried just Turning the top part a bit so it doesn't catch ?

I am not at my daughters at the moment so cannot cannot take any pictures. Was a bit wary about trying to turn it but will try tomorrow.

No, they normally screw into metal wing nuts under the pan part of the cistern. However, if you are trying to rotate the inlet valve a bit, you shouldn't have to undo the cistern from the pan, although there are some where you do unless you have the right sized box spanner. The normal procedure would be:
1. Water off, hopefully at an isolation valve.
2. Slightly loosen pipe connection nut to inlet valve shank (say 1/2 turn)
3. Hold inlet valve and slightly loosen valve securing nut under cistern.
4. Rotate valve.
5. Hold valve firmly and re-tighten securing nut.
6. Still holding valve, re-tighten pipe connecting nut.

Thanks for that I will be there tomorrow so I will give it a try

If the cistern bolts are plastic change them to some stainless steel ones. About £2.80 from toolstation. A lot better quality, less chance of the, leaking.

Cheers for that I will.

In a normal close coupled setup the screw heads are retained in a bracket, wing nuts/ nuts underneath;

Are you saying the plastic screws are inside the cistern bolted through the pan?

If it's bolt through the pan, the nuts need removing from below;

Yes they went through cistern and pan so I’ve changed them for the stainless steel ones when I moved position of inlet
