Connecting toilet to 15mm copper

[James100]

Hi,

This is my first piece of plumbing work, so treat me as if I know nothing (which isn't far off!)

I want to connect a toilet to the inlet pipe (15mm copper). I have read that a flexible connector is best, but these all look too long. I have no more than a few inches from the top of the boxing that hides the pipes to the base of the cistern, and I would like an isolation valve in that gap. The toilet didn't come with any nuts to connect the cistern to the inlet pipe, so I was wondering what is best to get a good connection between the base of the cistern (plastic thread) and the copper pipe? Is a normal 15mm compression nut good enough, or would that not give a water tight connection?

Any help/tips much appreciated!

Thanks

James

Depends on how big the gap is, whether the angle is straight-up or offset.

If you're a novice you might want to look at getting a push-fit connector.

Thanks for the info. It's a straight connection, the copper pipe is directly underneath the cistern inlet.

So does one end of that part screw directly onto the cistern, and the other pushes straight onto the copper pipe then? Or are those parts designed for plastic pipe?

Cheers
