My husband installed this, and for a moment, there was some adjusting where there was water leakage out of the pot-filler when water was cold and I had the sprayer on. But when I turned to hot water and sprayer, the leaking in the pot-filler stopped. We thought about sending back, but we decided to keep using it, and somehow, the leak stopped and hasn't come back, so we are very happy about that. The sprayer works great. So far, there has been not problems for the 3 weeks we've been using it. Seems to be well made.
