I have to run a new line to an expansion tank, incorporating a valve and faucet. I have done a hundred joints, but none for 15 years and I am a bit nervous. It is all 1/2", which I recall was really easy.
What has me concerned is that I once had trouble doing the second side of a coupling without having the first side fall apart. It was in a 2' crawlspace under a house, so I have an excuse, but still... Any tips would be appreciated.
