Hi Carpenter -
Does the Collins book go into much detail or is it pretty general?
I have the Readers Digest DIY Manual and the B&Q DIY Book and both give good overviews of plumbing, but I want to get a deeper knowledege of certain areas - e.g. soldering for gas pipes, testing that gas pipes are empty after killing supply before working, pressure testing - is a barometer necessary, more info on standard heating setups and also how to find a fault in the heating system. Do you happen to know of any books that covers all or some of the above?
