My mom spends winters in Cave Creek, so I needed to help her find a good plumber to replace her hot water heater and fix several other problems, including faucet valves and the main water valve that were basically seized up from calcium deposits.
I'm really glad I found Peace of Mind Plumbing during an Internet search. Joe came by and analyzed the hot water system and suggested installing a tankless water heater and integrated recirculating pump. He gave us a very good price for a modern Navien heater with a stainless heat exchanger and did a beautiful job installing it. The house now gets an endless supply of instant hot water.
Also, my mom has really nice faucets in the bathroom, but several had corroded cartridges, so the knobs were very hard to turn. Joe removed the bad cartridges and brought them to his plumbing supplier to identify the correct replacement cartridge. Most plumbers wouldn't bother doing this-- they'd just say you had to replace the entire faucet. Joe did a great job and the faucets work as good as new... and his charge was very reasonable.
Joe also pointed out that the water valves under the sink had frozen (no surprise after 20 years of Arizona hard water) and replaced those with better quality valves, so everything is in order now. My mom is thrilled!
If you're looking for a knowledgable, resourceful and honest plumber who is committed to customer satisfaction, I would heartily recommend Peace of Mind Plumbing
