In the above link it shows a FTC for 15mm pipe, but which size do i need to connect onto a bathroom sink ? is it 1/2" or 3/4" ?

I also want to use one on the toilet connector. What size do i need here ?

Is it ok to use these flexi connectors in these places ?

You want 1/2" for basin taps and float operated valve but they make the job look very DIY to me. I prefer rigid copper connections.

what about the connector to the toilet. is this 3/4" size. I am doing this is in a rental property i own so looks not that important. They will just give me a bit of flex if needed.

The connector to the toilet is 4". The connection on the float operated valve in the cistern will be 1/2". You're obviously aiming for a high class of tenant if looks don't matter.

1/2" it is. I reckon flexi looks fine and plan to do my own toilet with it.

Don't use flexis on potable water unless they are WRAS approved. The cheap foreign imports are known to harbor Legionnaires Disease and other nasties after installation.

Talking of flexi's I've replaced some that have sprung a leak in the middle a few times and in each instance they've turned black round the area first. Anyone know what process is going on there?

Usually happens if the inner butyle/rubber composition has a weak spot caused by thinning either in the manufacturing process or during installation if they become twisted or kinked when tightening.

I don't trust them on hot water systems as the rubber can become brittle from the inside due to heat and scale and eventually burst.

Copper will last for many years, flexis will not and with a little practice it becomes almost as quick bending a copper offset and fitting it compared to fitting a flexi.

I make up and keep a selection of offsets in the van for use when I need them. I find a 60mm offset fits most wash basins and pedestals.
