I'm running 1/2 inch "L" copper to plumb my bathroom. I was intending to use the same pipe for the risers and stubs, which will connect to shutoff valves with compression fittings.
I was going to use the standard Brasscraft valves available from HD. Someone told me that I can only use these types of valves with "M" copper.
Is this true? Should I buy some M pipes just for the stubs?
