This thread makes me very glad I sold my rental property in November.
I stopped shopping at H-D for plumbing parts a long time ago! Their valves, unions, etc are horrible, leak from the get-go and their copper fittings are very thin! They usually carry the cheapest of the cheap just to compete on price - my labor is worth more than a few dollars!
I now go to a regular plumber's supply company (locally) and get much better quality parts - most of which are actually made in the USA, some are not but still much better quality than the stuff from China.
