I want to thank Technician Sean D. and his associate Paul C. for during an outstanding job replacing some of my plumbing. They arrived on job site at the time promised and quickly determined my problem. They were both very friendly and professional. Sean was very knowledgeable as to what had to be done and made a good job an excellent job with a few tweaks. Atomic Plumbing is lucky to have employees of this caliber.


Wall thickness does not affect pipe or tubing size.[20] 1/2" L copper has the same outer diameter as 1/2" K or M copper. The same applies to pipe schedules. As a result, a slight increase in pressure losses is realized due to a decrease in flowpath as wall thickness is increased. In other words, 1 foot of 1/2" L copper has slightly less volume than 1 foot of 1/2 M copper.[citation needed]

Called in on Wednesday evening to schedule a new sink hookup and was put on the schedule for Friday morning with no problems. Ryan arrived and took a look at what I had, gave some recommendations and provided a couple quotes. He took his time and made sure everything he installed was the most efficient and correct for my setup. We will continue to use and strongly recommend Atomic Plumbing.

 James and Paul did an AWESOME job from start to finish with our toilet replacement and installation!! We unfortunately had a bad experience with our general contractor and his plumber and needed immediate assistance. I called Atomic and they immediately got me connected with a scheduler, then had James and Paul out to our house extremely fast! James and Paul were friendly, knowledgeable, professional, and efficient. They advised us based on their expertise and helped us pick out a new toilet and install it correctly. We are so grateful for their work and their professionalism. Would highly recommend them and hire them again!
