Water Filtration System Installation in Capitol Hill Seattle WA 98174
Seattle's municipal water supply is sourced primarily from the Cedar River and South Fork Tolt River watersheds — some of the cleanest municipal water sources in the country. Seattle Public Utilities consistently delivers water that meets or exceeds all federal and state water quality standards, and SPU's annual water quality reports reflect very good baseline water quality. Despite this, many Capitol Hill homeowners choose to add point-of-use or whole-home water filtration systems for enhanced peace of mind, improved taste, removal of trace chlorine and disinfection byproducts, and protection against potential issues with older building plumbing.
Capitol Hill Plumbing Seattle designs, supplies, and installs a full range of water filtration and treatment systems for Capitol Hill homes, condos, and apartments. Whether you're interested in a simple under-sink filter for drinking water, a comprehensive whole-home filtration system, or a medical-grade reverse osmosis unit, our team can assess your water quality concerns and recommend the most appropriate system for your Capitol Hill home and household.
Water Filtration Systems We Install
Under-Sink Water Filtration Systems
Under-sink filtration systems are the most popular starting point for Capitol Hill homeowners seeking improved drinking and cooking water quality. These compact systems are installed beneath the kitchen sink and connect to a dedicated drinking water faucet mounted on the sink or countertop. A quality under-sink filter removes chlorine, chloramine, sediment, and a range of other trace contaminants, significantly improving water taste. We install single-stage, multi-stage, and inline under-sink filter systems and can service and replace filters on any existing system you have.
Reverse Osmosis Systems
Reverse osmosis (RO) filtration is the most comprehensive point-of-use water treatment available for residential applications. RO systems force water through a semi-permeable membrane that removes an extremely broad spectrum of contaminants — including dissolved solids, heavy metals, nitrates, pharmaceuticals, and most bacteria — delivering essentially pure water at your kitchen tap. Modern RO systems include pre-filters, the RO membrane, a storage tank, and a post-filter polishing stage. For Capitol Hill homeowners with older homes that may have concerns about trace lead or pipe corrosion in their indoor plumbing, an RO system at the drinking water tap provides an excellent additional layer of protection.
Whole-Home Water Filtration Systems
Whole-home (point-of-entry) filtration systems are installed on the main water supply line where it enters your Capitol Hill home, ensuring that every faucet, shower, appliance, and water-using fixture in the home receives filtered water. Whole-home systems typically use large-volume carbon block or catalytic carbon media to remove chlorine, chloramine, and sediment from all household water — not just the kitchen tap. This benefits skin and hair during bathing, protects water-using appliances from scale, and provides filtered water for cooking at any sink in the home. Whole-home systems are an excellent investment for Capitol Hill families with children or individuals with chemical sensitivities.
Lead Service Line Concerns and Filtration
Some of Capitol Hill's oldest homes may still have original lead service line sections or lead-containing fixtures — a situation that can introduce trace lead into the water supply, particularly in homes that have been unoccupied for periods where water has been sitting in pipes. Until complete lead service line replacement (see our Water Line Repair page) is completed, a certified lead-reducing water filter at the drinking water tap provides important interim protection. We can recommend NSF/ANSI 53-certified lead reduction filters appropriate for your Capitol Hill home's situation.

📞 (888) 861-3658Seattle Water Quality and Capitol Hill Considerations
Seattle's municipal water is treated with chloramine (a combination of chlorine and ammonia) rather than chlorine alone, which is more stable and provides longer-lasting disinfection through the distribution system. Chloramine is safe at the levels used by SPU, but some Capitol Hill residents find that it contributes to a chemical taste or odor in their tap water, particularly in periods of higher treatment levels. Catalytic carbon filtration is specifically effective at removing chloramine — important to note when selecting a filtration system, as standard carbon filters are less effective against chloramine than catalytic carbon.
Additionally, Capitol Hill's older housing stock means that some homes may have galvanized or copper plumbing that contributes trace metals to water as it flows through aging pipes. A point-of-use filter at the kitchen tap — particularly an RO system — addresses any concern about pipe-contributed contaminants regardless of the quality of the municipal supply at the water main.

We provide filter replacement and maintenance service for all systems we install, and we can also service and maintain filtration systems installed by others.
