Replacement flush and fill valve

[XanderHarris]

I need to replace the fill valve on this, I was going to do the flush valve too. Can anyone recommend a good flush valve that will fit. The one that's in looks like a 2inch outlet.
Thanks

If I were to fit a fluidmaster one that has a 1.5inch cradle and an adapter washer for 2 inch holes. Would I notice a reduced flush volume?

We use the fluidmaster set as a replacement regularly never had a problem.
We always use fill valve with brass shank.

Thank you.

Would that push button swap for a fluid master?

If you want to have a fluidmaster and to be practically sure -

PRO820UK Mechanical Dual Flush Valve - Fluidmaster

Mechanical drop valve suitable for virtually all top activated cisterns with a 2" outlet. Adjustable full and partial flush volumes.

If the other button will fit then this is a great buy for you. You can mail Fluidmaster for the dimensions of the button then measure the cistern lid hole

In fact with a bit of looking - 40mm seems to be the size

Is that a better valve, then cable operated ones?

Not any better I wouldn't say. I've found it's all down to user interaction.

These valves usually only fail, or their buttons/rods, due to the way they are used. I've known toilets that have never had a button fail whereas I have 2 clients where I have had to replace the buttons 3 times and the damage is definitely caused by a heavy handed household.

The only ones I see fail consistently are the vacuum/pressure type buttons and that's usually a mechanical failure of the bellows in the button or the pipework hardens and breaks.

I think it's a great pity that the older, leak free, siphon flush systems have now been eliminated from all new toilet installations. Siphons went out of favour when water companies succeeded in getting cistern volumes reduced significantly in a bid to save water. The reduced volume meant that siphons often wouldn't reliably initiate, so cisterns with bottom flush valves became the norm. Trouble is, these valves often leak and this goes un-noticed by the average householder because the leakage is into the pan. I suspect these leakages waste more water than the older larger cisterns ever did, especially because the smaller cisterns often need multiple flushes to clear the matter in the toilet. A classic case of unintended consequencies!
