Running toilet, chronic clogs, wobbling base, or water on the floor? Our licensed plumbers repair or replace all makes and models throughout South King County.
📞 (888) 861-3658 — Same Day AvailableA malfunctioning toilet is one of the most common plumbing service calls we receive from homeowners throughout the 98158 zip code and SeaTac area — and for good reason. The toilet is one of the most-used fixtures in any home, and its internal components are subject to significant wear over time. SeaTac Area Plumbing Experts handles the full range of toilet repair and replacement services, from a simple flapper replacement to a complete toilet removal and new installation, for homes and commercial properties throughout South King County.
A running toilet is the most water-wasteful plumbing problem a homeowner can ignore. A toilet with a failed flapper — the most common cause — can waste between 200 and 1,000 gallons of water per day. At Seattle Public Utilities' current water and sewer rates, this can add $50 to $250 or more to your monthly utility bill. Over the course of a year, an unrepaired running toilet can cost a household $600 to $3,000 in wasted water charges. Our plumbers can replace a failed flapper or fill valve in 30 to 45 minutes, paying for the repair cost many times over in saved water bills.
The wax ring is the seal between the toilet's base and the drain flange in the floor. When this seal fails — which can happen due to toilet movement, floor settlement, or simply age — water seeps out at the toilet base with each flush, eventually soaking through the floor and damaging the subfloor and ceiling of the space below. In the moist Pacific Northwest climate, even minor moisture intrusion can quickly lead to mold growth in subfloor framing. A wax ring replacement involves removing the toilet, cleaning the flange, installing a new wax seal, and resetting the toilet — a routine job for our licensed plumbers that prevents potentially very expensive water damage.
When a toilet is cracked, extremely old, or so inefficient that replacement makes more economic sense than continued repair, we provide complete toilet replacement service. We will remove and haul away your old toilet and install the new unit completely — including supply line, wax ring, floor bolt caps, and seat. We work with all standard toilet rough-in dimensions and can accommodate most toilet models that you supply or that we provide.
For homeowners looking to upgrade, modern WaterSense-certified toilets use 1.28 gallons per flush or less, compared to 3.5 to 5 gallons per flush for older models. Washington State and many South King County utilities have periodically offered rebates for qualifying high-efficiency toilet replacements — ask us about current programs when you call.
Commercial toilets in the hotels, restaurants, office buildings, and transit facilities near SeaTac International Airport face much heavier use than residential units and require robust, commercial-grade components. We service commercial flush valve toilets (Sloan, Zurn, American Standard commercial models), ADA-compliant commercial toilets, and the high-flow toilet and urinal systems common in commercial restrooms. Our commercial toilet repair service is available 24/7 for facilities that cannot tolerate out-of-service restrooms during business hours.
A simple dye test can reveal a silent toilet leak. Drop a few drops of food coloring into the toilet tank and wait 15 minutes without flushing. If color appears in the bowl, you have a failing flapper that is wasting water even when the toilet appears to be off. This is one of the most common — and most easily fixed — sources of water waste in South Seattle area homes.
