So - I got the 20 mm adaptor for the T500 hoping that this would convert to something and found the thread is a 3/4\" bsp female thread. This fits practically nothing in our house but would work with a garden hose...
When I\'ve run the T500 I\'ve been using either the tap adaptor that came with the reflux or a barbed adaptor that goes on a shower fitting.
A quick trip round B&Q plumbing section today found a 1/2\" female to 3/4\" male connector.
So - remove the shower hose from the mixer tap, screw the female end of the adaptor onto the mixer tap, wrap a bit of PTFE tape around the the thread, screw the 20mm still spirits onto that and the needle valve onto that and it makes a lovely water tight fitting 
I hope this helps someone else out as it was a real pain finding something that worked !!Statistics: Posted by MrCat — Thu Dec 30, 2010 9:02 am
