We have a high level toilet cistern in the outside toilet that needs to be plumbed in so i was thinking of buying the copper pipe and pvc pipe and having a go myself but as i don't know much about plumbing i was wondering if someone could help me as i'm stuck at the first hurdle. The stop tap don't have a nut but it takes a 15mm pipe so i bought a 15mm x 1/2 inch tap connector and it won't fit as it's to small for the stop tap, so i was given a 15mm x 3/4 inch tap connector but the part that should fit inside the stop tap is to big so i was wondering what fitting do i need.
Need advice on what fitting i need for a stop tap

The end connections may be compression in which case you will need a compression nut and olive.
Does it look like this

Could you post a picture perhaps with a rule or tape measure next to it to give an idea of scale. One of the pro's on here will no doubt be able to identify the fitting.

If it's not 3/4" or 22mm and you say the 15mm pipe fits, then check the thread on the 15mm nut against the thread on the stop tap. Are they the same? 
I'm unable to post a picture as my bluetooth adapter ain't working. I have measured the hole of the stop tap and it's about 16mm so a 15mm copper olive will fit inside the stop tap as the stop tap has no chamfered edge. If the tap connector that i was given is 15mm x 3/4 inch it's not going to fit as the part that goes into the stop tap is 18mm. I will see if my uncle has got a 22mm nut or 3/4 nut in his shed and i will report back later.
Sell the high level toilet - and particularly the lead flush pipe Or if the cistern doesn`t work when you get water to it - I`ll sell you a replacement - High or low level I`ve been collecting old bits to make a retro bog in my house . We all really need a picture - the stopcock could be any type - particularly a fine thread Prestex fitting - they can be a b`ger

I think I`m right now - but you`re going to have to adapt itCould be a stopcock with 2 unions - and you got one missing
Try a 3/4 inch femail iron to 15mm copper compression coupling - and loads of ptfe on the threads
Would agree with Nige F. Maybe the origional pipe burst in winter with it being and outside loo. Have you had a good look around the garden, shed, attic etc, the old bit with the other half of the union might still be lying around. Long shot but worth a look.
