Toilet Troubles... PigletJohn please can you help?

[MaidenMotherCrone]

This is driving me nuts.

My toilet refill thing has reached the end of its days I think as it fills and then continues to trickle. I know it needs a new refill valve thing to replace the old ballcock etc but the problem is the flush thing. It's too big to fit a modern fill valve next to. Can I replace that too and if so what is it called?

Apologies for overuse of the highly technical term 'thing'.

Hopefully the pic shows what I'm trying (and failing) to explain.

Bump

Are you going to do it yourself, or get a plumber in?

Is the flush generally adequate, or would you like a more forceful one?

I think the fill valve is on a vertical stem that goes down through the bottom of the cistern, and the water supply pipe is attacjed with a brass or chrome or plastic nut. is that right?

I see from the cistern that you have soft water.

Do you find the old valve noisy?

If you put your thumb on the spout of the cold water tap in the adjacent basin, and turn it on, can you stop the flow with your thumb?

Sorry for the delay in answering and many thanks for responding to my cry for help.

In answer to your questions

I'm planning on doing it myself

1. Adequate
2. Correct

3.Not too noisy

1. No, it's not possible to stop the flow of water at the cold tap by covering with a thumb.

Do you think the water pressure/flow is too high?

the water pressure is normal for a supply taken off the mains (not via a loft tank) which your thumb indicates. In many parts of the country, and for people with a combi boiler, this is the usual way. Due to the high pressure, look at the instructions with your new valve. There will be a reducer in the packing, or a different-coloured cone, and you need to put the high-pressure one in.

You can fit a fill valve that is about the same as your old one

Opella is a good make.
You can see a spare red cone fastened to the arm in the illustration. The high-pressure one might already be fitted.

There is no need to change the flush valve, and this is often a much harder DIY job.

As the shank of the stem is plastic, you must carefully thread the nut on with your fingers and give it a bit of a turn to check it is straight before spannering. Plastic can easily be cross-threaded and damaged. I don't believe a brass one is available in that model.
