Public Service Plumbers did a couple of different things for me. They fixed a toilet of mine and they also did a much larger job that involved re-doing all the plumbing in my parents' bathroom. So my experience has been that they can do everything from the mundane little things like replacing the innards of a toilet all the way to extensive re-plumbing of a system. Everybody that I've met has been really great, both the technicians as well as the office staff. It's not cheap, but you get what you pay for. They're a solid provider.
