"They SAVED me $ 3,000. If you need help with a Tankless Water Heater - LOOK NO FURTHER! I had issues with my water heater b/c the temperature could not go above 100 degrees. My first plumber told me that i needed a new circuit board or a new water heater. The second plumber wanted to charge me $ 325 for a diagnosis. I found Affinity Plumbing on Angies List. They came over and was able to fix the issue with my temperature in about 30 minutes, saving me at least $ 600 for a new circuit board or $ 3,000 + for a new water heater as the other plumbers advised. They have REAL EXPERTISE in Tankless Water Heaters and are honest and professional. They are my NEW PLUMBERS! They deserve an A+"

"Response was quick and they carried through. My 2 tank water heaters cost $3900 including some copper pipe repairs next to the units, some welding and parts. The plumber was very knowledgeable and carefully explained everything I was interested to know. It was not an emergency but they came out that day and the next."

"Dennis with PDI did an inspection of our existing water heater and then replaced it with a new system. He did good work and was helpful with all of his recommendations. I would use PDI in the future and would recommend them to others."

"January 3rd, Attempted to chat online first with a representative. They were very responsive and able to answer my questions. Shortly after finishing the online chat, I received a call from their office to schedule the service. They were very accommodating of my schedule. The technicians arrived on time, were pleasant and knowledgeable, wore those plastic covers on their shoes. I needed the drains looked at in our upstairs bathroom but also asked them to take a look at the other bathroom, kitchen sink and backyard as I was noticing some stagnant water there. The Technicians were honest and up front - they diligently took care of the problem upstairs, told me everything else looked good elsewhere, showed me where grass had grown over the drainage from the back yard to the front, checked my water heater as a precaution. They were fair in their pricing and even offer a 5-year preventative maintenance plan that is extremely economical. I was absolutely happy with the service and would recommend JD Plumbing to anyone."

"I contacted Wallin plumbing for some quotes on a few projects. The Tankless water heater was going to be too expensive with the required electrical upgrade, the whole house water softener was recommended against because of the shape the pipes are in, but the particle filter may still be a go after the next paycheck. They were punctual, honest and knowledgeable...when it comes to which plumbers to hire, it's gonna be these guys!"
