"Great experience from start to finish. Our technician, Leo, was extremely thorough and upfront about possible solutions to our issue. He was very forthright and honest about everything that needed to be explored as he went. He even provided options for removing minimal drywall for a clean, safe replacement of the existing gas pipe. I appreciated his attention to detail to replace the line in the most clean approach with the existing structure -- not an easy task from what other competing bids were proposing. Great work from a solid company."

Affordable Plumbing, Rooter, and Water Heaters was established in response to a concerning industry trend. Many consumers are unaware that seemingly “local” Plumbing service providers are actually owned by Private Equity Firms or Investment Companies. As a result, prices are inflated, quality is compromised, and profit takes precedence over people in the home service sector. Service Technicians face lower wages and a lack of work-life balance. Our mission is to address these issues. We provide affordable solutions without compromising quality. We prioritize customer satisfaction and well-being, placing people at the forefront of our services. When you choose us, you can trust that fair pricing, high standards, and a supportive work environment for our technicians are our priorities. We strive for transparency, empowering customers to make informed decisions. With us, you receive excellence, integrity, and customer-centricity.

We at Aquaco, LLC, focus on quality water treatment systems over quantity. We use our years of experience and expertise, completing your project to perfection. Customer service and honesty are the most important aspects of our business and your satisfaction is guaranteed. Please call us today! We look forward to working with you. Please Note: Company will not install new equipment from other national vendors.

"First of all let me tell you that working with AquaCo has been an absolute treat! My wife and I meet Glenn at the Home and Garden show and we were impressed by his knowledge and upfront honesty when it comes to his craft. He was clear with the facts and upfront with the needs of our house. It was especially nice of him to video call us and adress our questions even though we had to take a out of town trip. So far 24 hours into owning our water softener my hair feels less crunchy after showers and our glass was practically spotless after my shower. I have also noticed that our water out of the fridge is already tasting better. If you are looking to adress the frankly terrible condition of your water especially in the Apache junction area, Glenn is your man, and the AquaCo team is a must hire!! "

Master Rooter is a full service plumbing company that specializes in drain and rooter services. We are a local owner-operated business that has 20 years experience serving the valley. Our technicians are available 24 hours a day 7 days a week 365 days a year.

"This was the second company I had come look at the leak in my toilet. The first one I thought was expensive. However he only wanted to replace the wax ring for the toilet for $600. So I contacted Angie's list and they sent out master router who to my surprise said I had a major problem in my home. That my walls had too much moisture and it was dangerous. The master bathroom supposedly had 100% humidity and the guest bathroom varied from 27 to 47% humidity. That was supposed to be very dangerous. They said my flange was below the tile level which they said was not right. I have since found out that is incorrect. I had not asked them to check out the master bathroom but they had me extremely concerned that I was living in a hazardous situation. Before I knew it, my guest bathroom was completely gutted and my master bathroom was partially gutted. A restoration company called copperstate came in on their tails and had me even more concerned about what was going to happen in my home.I erroneously thought they were under Angie's list also. I can't complain about the quality of the work from master router because it was good I was just not prepared to do $20,000 worth of repairs to my home. Especially since it was not needed from what the previous company had said. My insurance company is no longer responding and has paid only a portion of what things have cost me. and so I have now had to fork out nearly $20,000 and my master bathroom is still not finished. I do have to admit that they did find an issue with the repair done by Roto-Rooter in 2018 but that should not have cost me the kind of repairs that master router forced me to have done. I would not have had to have two major bathrooms gutted. I have not told him about things like the bubbler that they cut nor that I still am not happy with the cement repair but I am concerned because I've complained about him the cement several times. I'm afraid they won't ever make it any better. I would like it if master router could give me a partial refund because it would never have cost me this kind of money if they had just repaired the toilet the way the other company recommended. The toilet in the guest bathroom still has its original symptoms from the problem that the contractor was supposed to fix."

"I was referred to Reddi Services by a trusted friend to get a second opinion on some work that had recently been completed by another contractor. When their work did not resolve the original issue they suggested another solution, sight unseen. I called Reddi Services and asked for Chris Shuck based on his reputation for providing excellent customer service. I was not disappointed. He inspected the work that was previously done and cleaned up things that the others left behind. He thoroughly inspected the situation and presented pictures of where things could have been improved. When he left, I had a better understanding of what was addressed and what was done. I will recommend Reddi Services and Chris Shuch to my friends and relatives. 5 out of 5 stars. Thank you."
