To begin, I was very impressed with the delivery. UPS brought it at 7 PM a day early. I was concerned because the next day I had a doctors appointment and was worried that I would miss the delivery. The unit I replaced was a different make, but all the fittings were the same. So it was easy to install. Previously I had to replace some parts on my old unit and I had a terrible time with it leaking. It has been a few weeks since I installed the Waste King. It has never leaked. Again this is an easy unit to install. Works like a charm. No leaks. Will easily outlive me. Very powerful.
