Hear you on the PTFE lines.
Ordered around £400 worth of fittings, had a friend bring them back in their luggage for me and felt very smug that I had saved a load of cash....
Turns out I ordered rubber hose fittings not PTFE ones so half of them are now just expensive ornaments......
A note to Mum never needs explaining.
And!!! Pleased we finally get to see pictures of your handiwork.....
