John did a terrible job on the plumbing for my basement reno. The City came out to inspect his work and We failed inspection. All the floor lines for the new bathroom including vents were all hooked up incorrectly. He installed a primer for a floor drain and created a leak. His idea of fixing it was using duct tape. I made a mistake and paid him in full before he completed the job and i had to pay another plumber to fix all the problems.
