I had no idea how bad my drainage was until Rich arrived. From an upside down p-trap to many unnecessary pieces, causing slow draining and build up that eventually caused blockage beyond the wall. He cleared the drain and then took it upon himself to just fix it (he said it was usually it’s simple to rework, unfortunately, not in this case here). He minimized piping to just what was necessary, with all correct down flow and proper washers. Including cutting 45 from wall outlet and adding new trap adapter to make proper connection to Ptrap. Most PVC replaced with all new except a few pieces reused for under sink equipment connection. He also made recommendations for disposal use & maintenance. He did all of this, and spent nearly 3 hours, for a minimal fee. His clean up was great and the drainage is a work of art (see pic). We are truly grateful Rich showed up. I highly recommend him and will definitely use him again.
