Tankless Water Heater Maintenance & Repair Snohomish County, WA





Keeping Your On-Demand Hot Water Flowing
Need help with Tankless Water Heater Maintenance & Repair in Snohomish County, WA? Elite Plumbing & Sewer knows how to keep your on-demand hot water system in top shape. Tankless water heaters are great for energy savings and endless hot water, but just like any appliance, they need some care to keep working their best. Our skilled plumbers can fix issues and provide regular maintenance for your unit.
Regular maintenance for your tankless water heater, especially descaling to remove mineral buildup, is really important. This helps your heater run efficiently and last longer. If you’re not getting enough hot water, seeing error codes on your unit, or if the water isn’t as hot as it used to be, it’s time for a professional repair. We can diagnose problems with both gas and electric tankless models.
At Elite Plumbing & Sewer, we understand the technology behind tankless water heaters. We’ll carefully check your unit, explain any problems we find, and tell you what’s needed to fix it or keep it maintained. Our goal is to ensure you always have reliable, energy-efficient hot water.

Over time, minerals in your water (like calcium and magnesium) can build up inside the tankless water heater’s heat exchanger. This is called scaling. Scaling can make your heater less efficient, reduce hot water flow, and even shorten its life. Regular maintenance, especially flushing or descaling the unit, removes this buildup.
Most makers of tankless water heaters recommend having them professionally serviced (including descaling) at least once a year. If you have very hard water, you might even need it done more often. Regular service keeps it running efficiently and can prevent bigger repairs down the road.
Signs include not getting enough hot water or no hot water at all, the water temperature fluctuating (going hot and cold), seeing an error code displayed on the unit, hearing unusual noises from the heater, or noticing leaks around the unit. If you see any of these, it’s best to call us for a repair.

brandon rossiter2025-04-30 We had a sewer pipe break in our crawl space and couldn't use our water and they where able to come out and fix it same day! Awesome work and saved us from having to wait several days for another company. Rachel2025-04-29 Very professional. He gave a realistic assessment about my water line situation. He got the job done quickly, at a good price. Jake Melby2025-04-05 Anthony was great! Installed a new tankless water heater for me and my wife has never been happier! bradley vongphrachanh2025-04-01 Elite plumbing and sewer is absolutely just the best. They answer their phone and communicate effectively which is a trait many contractors lack. Anthony showed up when he said he would. Quickly diagnosed why we weren’t getting water to our faucets after a main water line break and repair from folks working on the exterior of our house. You don’t realize how much you depend on running water until you don’t have it and there’s a toddler and infant in your house who need it. I would not hesitate to call Elite Plumbing & Sewer in the future. Thanks again, Anthony! Travis Clark2025-03-18 We were recommended Elite from a neighbor, and we had such an excellent experience. Anthony was knowledgeable, fair, clean, and best of all quick! He diagnosed the issue and had it working very fast. Price was very reasonable, and lower than my other quotes. 5 stars! Jason Scoppa2025-03-07 We were referred to Elite by an HVAC company after being told only plumbing companies can work on radiant heating systems. Anthony came out quickly and gave us a really honest and thorough assessment of our situation. I appreciate his good communication in terms of coordinating the visit and post-visit followup, and felt like he gave us some options and a solid interpretation of our situation. He suggested we wait and not do anything at the moment. I'll definitely reach out to them again and would recommend them if you're having plumbing problems or radiant heat problems! Matt Hart2025-03-01 Anthony knocked it out of the park. Job was done fast, clean, and with top notch quality. Anthony will be my first call for any needs going forward, big and small. Chris Bierrum2025-03-01 Anthony provided excellent, friendly service! Showed up on time and I felt was fairly priced. Will recommend to my friends and clients! Timothy Hutchins2025-02-26 Anthony at Elite was responsive, fair, and knowledgeable. It's obvious he's been trained by the best dennis hafner2025-02-26 Anthony does great work, communicates the scope of work and costs up front. He was able to get me scheduled right away, was on time and priced fair. If I need a plumber again, I’ll be calling Elite Plumbing again.
