Kitchen Remodel Plumbing FAQs

Q: What plumbing work is typically involved in a kitchen remodel?
A: Kitchen remodels often include relocating or replacing water supply lines, drain lines, and gas lines for new appliances or sinks. We can also install new fixtures like faucets, dishwashers, and garbage disposals.

Q: Do I need a permit for plumbing during a kitchen remodel?
A: Yes—if you’re changing or moving plumbing lines, a permit is usually required in Seattle. Knockout Plumbing & Mechanical will handle all permitting and inspections to ensure your project is code-compliant.

Q: Can you coordinate with my general contractor or designer?
A: Absolutely. We regularly collaborate with contractors, electricians, and interior designers to make sure your kitchen remodel runs smoothly and stays on schedule.

Q: How early should plumbing be done in the remodel process?
A: Plumbing rough-in work should be done after framing but before drywall or cabinets go in. We’ll make sure everything is ready for final fixture installation later in the project.

Q: Can you help me move a sink, fridge, or dishwasher to a new location?
A: Yes! We specialize in fixture relocation and can reroute water, drain, or gas lines safely to accommodate your new kitchen layout.

As a restaurant owner in Seattle, I tend to find it infuriating when tradespeople over charge. It’s a real problem in this city. Knockout was fair and fast. Can’t say how much I appreciate it. I’ll be back for sure.

Knockout was great to work with - very courteous, responsive, and fair pricing. Zach came out to cap off a gas line for an appliance we switched to electric. The option was to do it from the inside or from the outside and remove the dedicated pipe altogether. Zach gave reasonable pricing (checked with two other companies) and was able to get the job done right away with expertise and professionalism. Knockout will be our top-choice, first-call for any future pluming needs in our home.

Excellent experience. I was considering replacing my water heater back in the spring and Knockout was one of the companies I shortlisted to talk to. Ultimately I decided to wait on replacement, but Knockout was definitely at the top of my list. When my water heater started leaking the other day, I immediately reached out to Knockout, and they were able to get me scheduled the next day! I was given the choice between Bradford White and AOS. Zach came out and did a fantastic job. Friendly but professional; quick and efficient but thorough. Knockout respected the quote I was given a few months back which was very competitive. I strongly recommend this company!

I asked these guys about hydrojetting our old sewer line that would occasionally get clogged. Zach showed up and looked at the situation, and after chatting for a bit he figured I could DIY it so I would know how to do it rather than paying every time it happeened. So he showed me a fitting for my pressure washer I could get, and described what to do. I did all that and it worked great, and I saved $850 that it would have cost, and then I knew how to do it going forward. They didn't even charge me. They're super honest guys with a lot of integrity. Definitely recommend them.

Zach is a consummate professional. He was thorough, timely, efficient, personable, and diligent. He returned the next day after the job to place a cover on a part, which is something my partner & I wouldn’t have known. Clearly, he has integrity, which in my book is paramount. We emphatically would not recommend anyone else, but him and his team for plumbing jobs. We were beyond pleased with Zach’s skill and caliber. 20/10 ⭐️

Zack and his crew replaced my kitchen sink drain after it started leaking. I was really happy with the price, and the speed and quality of their work. It was also easy to get a quote and schedule over the phone. I would definitely hire Knockout Plumbing again in the future!
