Very happy with our service. It was easy to schedule an appointment, they arrived within the arrival window they gave us, and fixed the issue with our tankless water heater quickly. The lead person was very knowledgeable and experienced. I overheard him training the new guy with him, and was impressed at his method, asking questions for the new guy to think through and answer. This further increased my confidence in their work. I will continue to go with them for water heater maintenance and repair. Thank you!

The technician who came out was very knowledgeable and answered all my questions on our water heater and hydronic radiant heating system. He pointed out that we had the wrong mixing valve with lead on our potable water lines and replaced it with a lead-free version right away. Would highly recommend their service.

I had a new tankless water heater installed last week. Tom and one of his employees came to help with the installation. The job took about 3-4 hours to finish. They were very professional and knowledgeable. I asked Tom couple questions regarding the water heater before and during the installations, and he answered all my questions. I would definitely use Washington Water Heaters for a future service - 5/5!

Our 5 year old water heater stopped heating over the weekend (WWH had installed it). We waited until Monday to call as we didn't need emergency service. They got service tech Ryan out same day. It was an easy fix and he checked and adjusted the heater while he was here. Excellent service for a fair price. If you need a new water heater or service th is company is great.

I appreciate Lam and his son's high quality service. Things are not going straight due to some technical issues. They came multiple times until everything is well set. They really care their customers and I am so happy to have them take care of my water heating system.

This is my second or third time working with them over the past five years — they installed two air-conditioning units and two water heaters for me. Every experience has been excellent. The crew is professional, punctual, and detail-oriented. Jeremy in particular stands out- answers all my questions with utmost patience. Their ongoing maintenance support has also been very reliable. Five stars, without hesitation.

Your company has helped us in a time of distress and when we needed some service on our boiler system. We did get quotes from other businesses but your company gave the best most honest pricing and your technicians were very kind, helpful and professional. We will definitely be telling our circle of friends about you. Thank you again!

I really appreciate the thorough and professional installation. They replaced my 50 gal tank water heater with a tankless. They were aware of what needed to be done and came fully prepared to finish the job in one day. No surprises, just methodically completing the job. I would recommend Washington Water Heaters without hesitation.

We had a problem that water in our bathrooms and kitchen was not coming hot enough and the issue was with the mixing valve. Other businesses were quoting double the amount and not guaranteeing their solution will fix the issue. Tom was excellent. He was quick to diagnose and recommend a solution, and then proceeded to do the fix, all within about an hour. We are very happy with the results. I’m glad I called Washington Water Heaters and I highly recommend this business to anyone looking for water heater related work.

Our old hot water heater broke, and they got someone out to our house the very next morning for a replacement. Dewey was super nice, super professional and worked fast to replace our whole setup in just a couple hours. I would definitely recommend this company for anyone who needs any hot water heater replacement or repairs. Couldn't be happier with the service.

Frequently Asked Questions

Do I need a permit for a water heater replacement in Federal Way?

Yes. The City of Federal Way Permit Center requires a mechanical or plumbing permit to install a new unit. Our crew handles the paperwork and ensures the entire installation meets current Washington state safety codes.

Are there local utility rebates for upgrading my system?

Yes. Puget Sound Energy (PSE) can provide rebates for energy-efficient home upgrades. You can capture significant savings by getting a heat pump water heater. We can guide you toward the right PSE-approved models to reduce your overall household electricity usage.

How does local water quality affect my equipment?

Dissolved minerals in the municipal water supply settle at the bottom of your tank. This layer of sediment acts as insulation between the burner and the water, forcing the system to work overtime. Routine flushing helps avoid premature hot water tank servicing. If your unit makes rumbling sounds or struggles to keep up with demand, contact us for prompt water heater repair.
