Peterson Plumbing is in an out of the way part of Richfield, and the store inside is more like a warehouse or auto parts place than a showroom. But they do offer all kinds of professional quality plumbing supplies, including hot tubs, ways to clear pipes, and much more. The best reason to use them is the enormous amount of experience and helpful advice their staff offers. I once had a stubborn clog and they were the only ones in town who understood what I was talking about and told me what I should try and why. They actually steered me away from a more expensive solution that could have caused me problems. I really appreciate that kind of honesty. Highly recommended.
