Frequently asked questions
Does Seattle tap water need to be filtered?
Seattle's municipal water supply from the Cedar River and Tolt River watersheds consistently meets or exceeds federal and state water quality standards. However, many Seattle homeowners still choose to install filtration systems to address taste preferences, chloramine smell, sediment from older pipes, or peace of mind for households with young children or immunocompromised individuals. Whole-home systems also protect appliances and plumbing fixtures from sediment and scale buildup.
What is the difference between a water softener and a water filter?
A water filter removes contaminants, sediment, chlorine, chloramines, and other particles from the water. A water softener specifically addresses water hardness by removing calcium and magnesium ions through an ion exchange process. Seattle's water is generally considered soft compared to many US cities, but some neighborhoods served by older pipe systems may benefit from both filtration and softening. Beacon Plumbing's licensed plumbers assess your specific water quality situation and recommend the appropriate system.
How much does a whole-home water filtration system cost in Seattle?
Whole-home water filtration system costs in Seattle vary based on the type of system (sediment filter, carbon filter, reverse osmosis, UV), the size of the home, and any plumbing modifications required. Beacon Plumbing provides upfront pricing before any work begins with no trip charges for the assessment visit. Call (206) 720-2040 to schedule a same-day consultation from a licensed Seattle plumber.

What Seattle customers are saying
Thousands of verified reviews from homeowners and businesses across the Puget Sound.
"We noticed a chloramine smell in our water and decided it was time to do something about it. Beacon installed a whole-home carbon filtration system that addressed the taste and odor completely. The install was professional and clean, and the tech explained the filter replacement schedule clearly. Our water tastes better and our showerheads are not building up the mineral deposits they used to."
Melissa A. | Madrona, Seattle | Whole-home filtration system
"With a new baby in the house we wanted better quality drinking water and did not want to deal with countertop filters or buying bottled water. Beacon installed an under-sink reverse osmosis system that fits neatly under the kitchen sink. The water quality is noticeably better and the install was quick and tidy. Worth every penny."
Daniel C. | North Seattle | Under-sink reverse osmosis
"We were going through dishwasher heating elements and water heater anode rods much faster than we should and our plumber suggested it was mineral buildup. Beacon installed a water softener and within six months our fixtures and appliances were in noticeably better shape. The installation process was straightforward and the ongoing maintenance is simple."

Owner, Beacon Plumbing
Founded 1995
A message from the owner
Built on hard work and a commitment to this community
Bill Cahill started Beacon Plumbing in 1995 with five trucks and a simple philosophy: hire great people, work hard, and treat every customer the way you would want to be treated. Thirty years later, that philosophy has not changed. What started as a small Seattle operation has grown into a team of 100 licensed, bonded, and insured technicians working around the clock to serve homeowners and businesses across the Puget Sound.
Bill believes deeply in giving back to the community that has supported Beacon's growth. Over the years, Beacon has sponsored the Miss Beacon Plumbing hydroplane at Seattle Seafair, supported Crime Stoppers of Puget Sound in the fight against human trafficking, donated musical instruments and a music teacher to St. George School, and partnered with Northwest Harvest, Ronald McDonald House, and Mamma's Hands. The Seahawks and Mariners logos on Beacon trucks are not just sponsorships - they are a reflection of Bill's pride in Seattle and the people who call it home.
When you call Beacon Plumbing, you are not calling a national franchise. You are calling a company that was built here, employs your neighbors, and is invested in this region for the long haul.
