"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+"

"Terrific response time! Called for quote at 12:24 pm. Jim quickly evaluated my need for two 50 gallon gas water heaters. Recommended Bradford White gas water heaters to replace my 20 year old rusting water heaters. His crew of 3 arrived at 1:30 pm and by 3:30 pm new water heaters installed and old water heaters removed from 3rd story walk in attic. Very efficient and clean installation. Price exactly as quoted. If you need water heater replacement call Jim at Water Heater Pros!!!"

"Highly recommend this company. All contact with the office and the technician were very professional and I found all to be very courteous. They came out to fix a leaking valve in my Kitchen on short notice and on a Sunday Their fees were very fair. I will use them next time I need a plumber. ."

"Fantastic job. Flushed out my tankless water heater then installed something that cleans water so I never have to have it flush d again. So happy. They also fixed a leaking outside faucet that lid put insulation they did not charge me for. I highly recommend them."

"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."
