"Heating was working afterwards. Job well done."

"It went well. The guys who installed the water heater were very professional and answered my questions."

"Great experience with Aqua Knight. Walked through the estimate on Saturday. Came first thing Monday and knocked it out. Would recommend them for anyone needing a new hot water heater."

"They were very responsive and able to replace my water heater quickly. I was given several options for the replacement. Lenny was excellent"

"I had a couple leaky outdoor water spigots that would have been an easy fix for me to do, but I couldn’t get the rusty bolt out to remove the handles so I could access and replace the washers, etc. I reached out to several plumbing companies and explained the task. They refused to come out to repair it and would only do a complete replacement for several hundred dollars per spigot. Ryan discussed the task with me and came out the next day to make the repairs. He was even able to “MacGyver” the part I had to make it work since it was a discontinued part, saving me the cost of replacing the entire apparatus and having a hole cut out of my drywall in my kitchen. The job was done really well for an incredibly fair price. I’m super grateful to now have an honest, affordable plumber on my speed dial for any future needs! I highly recommend Ryan. He does great work and is super kind. Thanks, Ryan!"

"Very professional, friendly, clean and fast. He even fixed some bad plumbing the original installer had put in, without charging or complaining. Price was what he quoted plus a few hoses and valves that had to be replaced. Would definitely hire again."

"Outstanding service from start to finish. The technicians were phenomenal and took care of every detail, from removing our old unit to installing the new tankless water heater. The job required custom retrofitting and running new piping to make sure the unit fit properly, and the crew handled it all seamlessly. Clean, efficient, and top-tier craftsmanship. I couldn’t be happier with the results and highly recommend them."

"We had Chad from Cosmic Plumbing out to replace our old water softener. He was very professional and informative from start to finish! He was fairly priced and easy to work with. Highly recommend for all your plumbing needs!"

"It couldn’t have gone better! Carl was experienced, knowledgeable and friendly. Plus, he smelled gas which is why he replaced the valve on my water heater. It was a great visit!"
