Our Roman bathtub faucet was leaking for a few days while we waited for the home owner’s warranty licensed plumber. Got tired of waiting and called affordable plumbing. Great decision from the start. Phone operators were helpful and got us scheduled that day. Jason came out and gave us a reasonable price and started working right away. Stopped the leak and came back the next day to install the new faucet. We are delighted with Jason and would highly recommend the company.

How nice to have clean, fresh tasting water! Jesse took great care of us. He not only installed a new RO system, he also cut out and replaced the rotted, moldy wood under the sink. It looks amazing! While there he flushed out the tankless hot water heater and gave us lots of good information about water softeners and conditioners. He is very water knowledgeable and we are very pleased with his work.

I needed a bathroom drain cleared. After being seriously disappointed by a plumber assigned to us by American Home Shield, I asked AI (artificial intel) to recommend the top rated plumber in Scottsdale. AI recommended Zest Plumbing & Drain. I was not disappointed. From my first contact with Diana the dispatcher to Wally the field supervisor my experience with Zest Plumbing was outstanding. The AHS plumber gave up (without trying very hard) on clearing my drain and recommended tearing out a vanity and the toilet to install new pipes because he said my CAST IRON pipes had collapsed...it was baloney! AHS calls this a "MODIFICATION" which is not covered by the warranty. Don't fall for this tactic! Wally from Zest brought in his equipment and 30 minutes later my drain was working properly. He even showed me a video of my clean drain. Before you start tearing out walls give Zest a call!

Wally Fields assisted me with a water filtration issue. He was amazing! He walked me through how the filtration system worked and explained clearly what was going wrong. He was able to quickly diagnose the issue. He did not have the supplies needed to fix it at the time, but he left to get it and came back the same day to complete the job. He was quick and efficient and the system is working great now. I can't thank Wally enough for his incredible service.
