We serve residential and commercial properties throughout the Renton area with reliable, professional toilet installation and repair services.

Common Toilet Problems We Fix

Running Toilets and Constant Water Flow

A running toilet is one of the most common issues we encounter in Renton homes. Most people assume they need a complete replacement, but often a simple repair solves the problem. The culprit is usually a worn-out flapper valve in the tank—the rubber component that controls water flow from the tank to the bowl. When the flapper deteriorates, water continuously leaks into the bowl, and the tank refills constantly. This not only wastes water but can increase your monthly water bill noticeably.

We diagnose the exact cause of your running toilet and recommend the most cost-effective repair. Sometimes replacing just the flapper kit is sufficient. Other times, the fill valve or overflow tube needs attention. Our technicians inspect all internal components to ensure we address the root cause, not just the symptom.

Leaks at the Base and Supply Line Connections

Water pooling around the base of your toilet indicates a seal failure, often at the wax ring between the toilet and the flange. This is a more involved repair that requires removing and reinstalling the toilet. We also check supply lines for leaks—these flexible connections can wear out over time, especially if they're corroded or improperly secured.

For supply line connections, we work with quality materials including Type L copper pipe for durable residential water lines, ensuring your connection won't develop problems down the road. We'll also assess your water pressure. If your home has high water pressure, a pressure-reducing valve (water pressure regulator) may be necessary. Excessive water pressure damages fixtures and supply lines prematurely, and installing a regulator can extend the life of your entire plumbing system.

Clogs and Drainage Issues

A toilet that won't flush properly or drains slowly needs prompt attention. Most clogs in residential toilets result from improper items being flushed or mineral buildup in older plumbing. We use professional-grade plumbing equipment to clear blockages without damaging your porcelain fixtures.

When we address drainage issues, we also evaluate your home's drain system. Every horizontal drain run longer than 100 feet and every change of direction more than 45° needs a cleanout for accessibility. If your home lacks proper cleanout placement, we can recommend strategic locations that allow for easy maintenance without removing drywall. A $50 cleanout installation now saves $500 in wall repair later when a drain needs snaking—this is a smart preventive measure many homeowners overlook.

Toilet Replacement and Installation

When Replacement Makes Sense

If your toilet is old, damaged, or constantly requiring repairs, replacement becomes more economical than ongoing fixes. Modern toilets use significantly less water than older models—newer efficient toilets use 1.28 gallons per flush compared to older toilets that used 3.5 to 7 gallons. For families in Renton, this translates to noticeable savings on water bills over time.

We also install toilets when remodeling bathrooms or building new homes. Our team handles all aspects of installation, from rough-in plumbing during construction to final fixture installation.

Proper Installation Techniques

Installation seems straightforward, but improper techniques cause problems later. We ensure:

• Correct flange positioning: The flange must be at the proper height relative to finished flooring
• Proper wax ring seating: We use quality wax rings (or wax-free alternatives) and seat them correctly to prevent leaks
• Secure bolting: Overtightening bolts cracks porcelain; we apply appropriate pressure for a secure hold
• Water supply connection: We verify proper flow rate and ensure no leaks at connection points
• Venting assessment: Toilet drains must be properly vented to prevent siphoning and slow drainage

Materials We Use for Reliable Installations

When we install or repair your toilet's water supply connection, we use quality materials built to last. Type L copper pipe is our standard for residential water lines—it provides durability and won't degrade over time like some plastic alternatives. For homes where rigid piping is preferable, we also work with CPVC (chlorinated PVC) pipe, which is specifically rated for hot water applications and provides a rigid, corrosion-resistant option.

For newer installations involving PEX tubing, we follow professional standards. When using PEX, we leave 6-8 inches of slack every 10 feet to allow for thermal expansion and contraction—PEX can expand up to 1 inch per 100 feet when heated. This prevents stress on connections and extends the lifespan of your system. We also never use PEX outdoors since UV light degrades it within months.

Protecting Your Home from Sewage Backup

If you've experienced or worry about sewage backup in your Renton home, we can install a backwater valve—a one-way valve that prevents sewer backup from entering your home through drains and toilets. This is particularly valuable for homes below street grade or in areas prone to heavy rainfall that overwhelms municipal sewer systems. The backwater valve allows normal drainage but blocks any reverse flow, protecting your home from a serious and costly problem.

Why Professional Installation Matters

DIY toilet installation often leads to leaks, improper venting, or weak seals that fail within months. Professional installation ensures your toilet functions properly, doesn't leak, drains efficiently, and lasts for years. We stand behind our work with thorough testing before we consider the job complete.
