Best Relief Valve in Madison WI

Having used HJ Pertzborn plumbing in the past, I was disappointed that they now refuse to work on my newly plumbed house because they weren’t the plumbers who did the work. We fired our previous plumber (that’s a different review) and needed help with installing a couple of sinks. I called Pertzborn and they said they would not accept any work at our house “in case the previous plumber did something wrong.” So, basically, city of Madison inspection means nothing and they don’t want to work on your house if they didn’t plumb it initially. Ironically, HJ Pertzborn himself plumbed our house n the 1930s, they just weren’t hired initially for the job by our contractor. Good to know.
