Re: Trouble with compression fittings
You don't use pipe dope or teflon tape with compression fittings. I don't personally care for them myself, but do use them when necessary. The key is that the parts must be clean and you use two wrenches that fit the fittings so that you can set the wrenches in a "V" shape and squeeze them together, tightening the nut with sufficient force. As they come up to being tight enough, they'll squeak as you continue to tighten. The fittings are tight enough when you no longer have leakage.
If your angle stops don't shut off tight enough, then I recommend turning off the water at the main and either replace the valve if you want to keep them for future use OR remove the valve and install caps. With the water off at the main, you should be able to drain the water out of the plumbing system enough so that it doesn't drip and the connection can be soldered.
