1/2" or 5/8"?
Quick question. I bought a new bathroom faucet and the piping. I checked all the bins for the shutoff valves, and i could not find one with 1/2" OD inlet, 3/8" outlet for copper pipe compression fitting. The ones I ended up buying are 5/8" OD inlet, 3/8" outlet. I did see the 1/2" inlet in iron pipe thread-type, and for sweat fitting. Am I correct in assuming that there is no 1/2" OD inlet for compression fitting, and are the valves I bought going to work with my plumbing. Plumbing is standard midwest under-sink plumbing. Thanks.
