Joseph Mangrella, with Diamond Plumbing and Drain Cleaning, LLC, has very poor work quality, and customer service: - The tub moved after being installed. Joe just told me to use some spray foam. This didn't help. I had to figure this out on my own using mortar and extra wood. - Tub was not installer correctly, the waste pipe under the tub leaked, which another plumber needed to fix. - Joe installed the posi valve and tub placement out of line, which forced me to buy a valve extension. A good plumber would never make this mistake. - The shower head, posi valve, and spout was not aligned vertically, which does not look good. - The copper pipe for the spout was loose and came out at an angle. This caused a problem installing the new spout properly, with a big gap between the tile and spout. Joe simply left the job without installing it properly, leaking behind when wall turning on the shower. When I asked him to come back and fix the bath spout, he wanted another $150, on top of the $950 I already paid him to install the new tub. I had to hire another plumber to fix the problem. I would never hire Joseph Mangrella, with Diamond Plumbing and Drain Cleaning, LLC.
