"I love these guys and they will be my go-to for any work they do in the future. I replaced a toilet myself but still had some issues with water leakage. They looked things over a d verified I did the toilet replacement correct but were able to identify the leak and help me address it."

"Zach and his crew were amazing! Our old water heater sprung a massive leak at 2:00am on a Saturday morning. Contacted Zach at 7:30am and he called right back and was here within the hour. Not only did we replace our water heater with a tankless model, but also moved it from the second floor to garage. Zach did all of this on a Saturday for a flat fee!! He and his crew were here for 9 hours without complaint or even seeming to take a rest!! Knockout Plumbing is indeed a 'Knockout' and I would highly recommend!! Kudos to all!!"

"Nate did an amazing job installing a new toilet in our outdoor bathroom for guests to use while swimming, as well as replacing our leaky outdoor faucet. Everything is working great! We’re absolutely loving having the toilet available again, and the faucet no longer leaks and is so quiet when the water is running. Nate showed up on time, worked hard, and did a wonderful job. I’m extremely grateful and will definitely reach out to him again if we ever need more plumbing assistance. Highly recommend!!"

"Miguel is my new plumber from now on- he was very patient in explaining what I needed to know about the job on hand. He was very polite and made sure I was comfortable with the choice I made. He also gave me proposals for a future project (possibly changing my water heater because itâ s 11 years old now , no issues-not leaking but I want to be proactive and to increase the property value as well). I will gladly recommend him to anybody who needs a new plumber. Heâ s just down right AWESOME!"

"We were in dire need of a water heater blowout, and Home Advisor was quick to find us the help we needed, in Puget Sound Plumbing and Heating, INC! The crew were prepared with a replacement unit, had it installed and contacted a Water Mitigation Contractor, who also arrived and have provided us with a quote for insurance claim. Not an emergency by any means, but these fellows responded like it was! Super impressed!"

"Mark was able to replace my water heater quickly and efficiently and went the extra mile to make sure I understood the function of the heater and the water leak gauge -- my old one was improperly installed and submerged by water (super helpful. not.) On a follow-up call he even turned me on to a trusted electrician, cuz I need a bathroom ceiling fan installed. Two thumbs up!!"
