Is copper pipe the holy grail in Udon Thani...Or is 15mm the utopia? any ideas on were to go. Forget Global and Home pro been there, a few scruffy shops in the city that sell brake pipes also tried. i am at my wits end!

While I can't answer this one I would like to add that I was wondering for some time who would be able to do the copper work - until I had to move the aircon. The worker had everything for perfect copper treatment, gas soldering, bending tools etc.

So if you find the pipes it can be done!
