I decided to use Bill Howe to replace my standard Wilkins pressure regulator because they are located right around the corner from me. I knew going in that there was a 1 hour minimum at $169 quite a bit more than my previous plumber at $110. It was a small job (30 minutes) so I decided to give them a try.
I will not use them again or recommend them to friends or neighbors. The plumber was great but the markup on this standard pressure regulator was robbery. Howe marked up the price over 50% more than Home Depot or Amazon. Of course these stores already have their overhead and profit incorporated into their prices.
