Plumbing Services in Seattle & Western Washington

Proudly serving the Western Washington area with over 20 years of water treatment experience.

When something goes wrong with your plumbing, you don’t just need a quick fix—you need a solution that protects your home, your fixtures, and your water quality for the long haul.

Pure Water NorthWest now offers full-service residential plumbing, delivered by the same local team Western Washington already trusts for clean, great-tasting water.

Whether you’re dealing with an aging water heater, low pressure, rusty water, or a plumbing project tied to a remodel, we’re here to help—scientific, not salesy, and always focused on what’s best for your home.

A plumbing team that understands your water

For most homeowners, plumbing and water quality are two sides of the same problem. Hard water, iron, sediment, and bacteria don’t just affect taste—they wear on pipes, fixtures, and water heaters over time.

Because Pure Water NorthWest has spent years diagnosing and treating water issues across Seattle, the Eastside, and the Kitsap Peninsula, our plumbing work starts with a deeper understanding of what’s actually moving through your pipes. That means smarter recommendations, longer-lasting repairs, and fewer surprise problems down the line.

Comprehensive Plumbing Services in Seattle & Western Washington

From small repairs to full system upgrades, our licensed plumbers handle the most important plumbing jobs in your home, including:

Water heater installation & replacement

 Upgrade from an undersized or failing unit to a properly sized, high-efficiency water heater. We’ll help you select the right fit for your home, install it to code, and make sure it’s set up to handle your family’s hot water needs.

Tankless water heater solutions

Interested in endless hot water and better energy efficiency? We install and service tankless systems and can help you understand what’s required in terms of gas, venting, and water quality so your investment pays off.

Water heater repair & troubleshooting

No hot water, inconsistent temperature, leaks, or strange noises—our team can diagnose the issue, explain your options clearly, and help you decide if repair or replacement makes more sense for your home.

Repiping & pipe replacement

Older galvanized or corroded pipes can lead to low pressure, discolored water, and recurring leaks. We offer whole-home and targeted repiping solutions designed around your home’s layout and water demands.

Sewer and drain issues

Slow drains, recurring clogs, or suspected sewer line problems are more than an inconvenience. We can investigate the source, recommend targeted repairs, and coordinate more extensive work when needed.

Gas line repairs and upgrades

From water heaters and ranges to outdoor appliances, we handle select gas line repairs and new line installation in conjunction with plumbing projects, always with safety and code compliance at the forefront.

If you’re planning a kitchen or bath remodel, replacing aging plumbing, or simply trying to solve a recurring problem, our team can work alongside your contractor to protect your new fixtures and ensure everything is plumbed for long-term performance.

Better Water, Better Plumbing

Clean, properly treated water doesn’t just taste better—it helps your plumbing system work better, too.

Hard water and high mineral content can cause scale buildup inside pipes and water heaters, reduce efficiency, and shorten equipment life. Iron, sulfur, and sediment can stain fixtures and lead to ongoing maintenance headaches. Because plumbing and water treatment are under one roof here, we can:

Pair plumbing work with smart water treatment

When we install or replace a water heater, repipe parts of your home, or address recurring issues, we can also look at how a whole house water treatment system or water softener might protect that investment.

Solve root causes, not just symptoms

Leaks, stains, and frequent fixture replacement often point to underlying water issues. We can test, diagnose, and design a solution that supports both your plumbing and your water quality.

Coordinate service and maintenance

Instead of juggling multiple vendors, you can rely on one team for {water treatment services}, plumbing repairs, and future maintenance.

If you’re already a Pure Water NorthWest customer and you’re planning plumbing work, let us know—our team can make sure your existing systems and new plumbing are working together.

Plumbing FAQ

How do I know if I should repair or replace my water heater?

Most water heaters last around 8 to 12 years, depending on usage, water quality, and maintenance. If your unit is near the end of its expected lifespan, leaking from the tank, or requiring frequent repairs, replacement is often the most cost-effective option. If it’s newer and the issue is isolated—like a failed component or thermostat—a targeted repair may make more sense. Our team will walk you through both scenarios so you can decide with confidence.

In addition to water heater installation and repair, we can help with repiping and pipe replacement, select sewer and drain issues, and certain gas line repairs tied to water heaters and other plumbing fixtures. If your project also involves water quality concerns, we can coordinate plumbing work with {water treatment services} so everything is addressed at once.

Yes. We install and service tankless water heaters, including evaluating whether a tankless system is a good fit for your home. That includes reviewing your existing gas or electrical capacity, venting, and water quality. Because tankless systems are especially sensitive to scale and sediment, we often recommend tailored water treatment to keep them running efficiently and extend their lifespan.

Common signs include low water pressure throughout the home, frequent leaks, discolored or rusty water, and visible corrosion on exposed pipes. In older homes with original galvanized piping, repiping can significantly improve reliability and water quality. We can inspect your plumbing, explain what we see, and design a repiping plan that fits your budget and priorities.

Yes. Many of our customers rely on well water, and we’re very familiar with issues like iron, sulfur (rotten egg smell), and sediment. When we work on plumbing in well water homes, we consider both your plumbing system and your well water treatment setup. That way, repairs and upgrades support your overall water quality and not just today’s fix.

 Simply contact our team, tell us what’s going on, and we’ll help you schedule a visit that fits your calendar. When needed, we can often coordinate plumbing work with {well water testing and treatment} or {HVAC services}, so you’re not juggling multiple companies or repeat visits.

Yes. If you’re planning a kitchen, bath, or whole-home remodel, we can work with your contractor to handle plumbing rough-in, fixture installation, water heater upgrades, and any needed water treatment changes. Our goal is to protect your new fixtures, support your project timeline, and make sure everything is set up for long-term performance—not just day-one inspection.
