"They were great to work with and more competitively priced than culligan. We were selling the home the water system was going into and needed to get the work done quickly before closing to address issues on the inspection report. They were great to work with and very responsive. We ultimately had installed a basic water softener, UV system and new sediment filter housing."

"Excellent experience during a bad situation. We discovered our well head was leaking on a Sunday afternoon. Joe, the owner, came out the same day to assess the problem and told us how to avoid burning out the water pump. Joe and his crew came out the next day. Repaired the problem, with no surprises. He took the time to explain what was wrong and what he needed to do. Very professional, courteous, and knowledgeable. Everyone at Old Faithful Pump Co is friendly and it was pleasure doing business with them. We recommend Old Faithful Pump Company to everyone."

"They just installed a heat pump system and water heater. Jared provided invaluable information about the options and supervised the work. Ray handled all the arrangements and paperwork. They were highly professional and client service oriented. Installers were very clean and responsible. Highly recommend."

"Kyle and John from In Town Plumbing were great in their install of my RO filter system. Kyle, the lead on the job, was a good communicator and patiently answered all of my questions. They worked efficiently together and I could tell Kyle knew what he was doing, and they finished the job in no time. I took off one star (would have just taken off 1/2 star but that's not possible on Angi) because they were planning to install the drain line *after* the P-trap, instead of before it, which is just not the best practice. Fortunately I had researched this beforehand and read the RO system's manual (and they were happy to fulfill my request). Otherwise I was super pleased with In Town's work, and with their courtesy (on the phone and in-person), along with their very reasonable pricing. I'd definitely recommend In Town to others!"

"Nate called me quickly after my request had been submitted for a replacement 40-gallon natural gas hot water heater. Nate made an excellent first impression; as I spoke to him on the phone, I knew he knew what he was talking about. The heater was installed that day with meticulous attention to detail, and the price was below the initial quote."
