This goes to show how opinions differ on these things. I happen to agree with Master Plumber Mark somewhat. I like Delta, Amr. Std. and Moen. My experiences with PP are not favorable. However, I do realize tha PP so dominates the market that on a % basis it might be comparable. There are just so many of them out there that you naturally see more repairs. It is a slight pain that they have had som many stems over the years that were similar but not interchangeable. Some of their worst designs were the hydroseal ( lousy chrome on the stems) and those long thin widespread lav stems (Marquis) with the huge handles and the tiny 00 washers.
