M. Thao
I was referred by my roofing contractor to go with John to do my water heater. Very professional did a great job. Very fair price. I am very please with the job he and his crew did. Will do more business in the near future. Thank you!

I had decided to hire John Conner Co LLC for my Lead Service Line Replacement. After receiving several quotes John came in with the lowest quote, luckily for me. They came in and directional bored the new poly service line and I didn’t have to worry about removing and replacing my fence/ landscaping / and concrete sidewalks. The crew was on time and courteous throughout the entire process. Great group of people working here. Thanks John.

We had an exceptional experience with John Conner Plumbing! From start to finish, the team was extremely professional and showed great respect for our home, making sure they left the work area cleaner than they found it. Their attention to detail resulted in quality work that fixed our issue perfectly. We were also thrilled that their quote came in well under their competitors' estimates. Highly recommend John Conner Plumbing for reliable service and great value!
