"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."

"I cannot say enough good things about this company. A power outage at our house over a weekend caused a lot of damage to various motors throughout the house. Joe called very quickly after I left a message (on a Sunday!) and went through a lot of possible things to check in order to try to save my paying for a service call (much appreciated). Ended up scheduling an appointment for 8 a.m. the next morning. He was here on the dot and quickly diagnosed the problem. Fixed not only that, but helped my husband get other things restarted as well (water filter and hot water heater) before he left. The best experience ever with a service professional -- I'd highly recommend him and Old Faithful anyone with well or well pump problems."

"John was very knowledgeable and efficient. He took time to analyze the plumbing issue that we were having to identify the source of the water leak. He explained the problem and let us know what our options were. John got back to us with an estimate within an hour. The repairs were done within the next couple days. His work was impeccable and I would highly recommend this plumbing service."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"Very positive experience with Tim and his crew. We have horrible well water, and there were time constraints due to real estate purchase. Everything was done within the specified time-frame, neat and professionally. Responsive to inquiries, and helpful in educating during the process. They offer competitive pricing, and there is no pressure. You can tell that their main goal is to provide safe water to their clientele. It has been a few months since completion, and it is nice to have peace of mind that our plumbing, fixtures, and appliances are protected by some of the best equipment on the market."
