Few plumbing repairs feel as urgent as a toilet that will not stop running. In most cases the culprit is a worn flush valve—the assembly that releases water from the tank into the bowl. Knowing the realistic flush valve replacement cost helps Portland-area homeowners budget wisely, avoid surprise mark-ups, and decide whether to DIY or hire a professional. CountBricks brings clarity to that decision with instant voice-powered estimates that pull live material pricing and verified labor rates into one shareable document.
The flush valve is the plastic or brass fitting at the tank’s bottom. It partners with the flapper and handle to deliver a measured rush of water. Common failure points include cracked overflow tubes, warped seats, or mineral-encrusted gaskets. When any piece breaks down, water seeps continuously into the bowl, driving up utility bills and posing a slip hazard around the base.
• Constant running or “phantom flushes”
• Water level dropping in the tank between flushes
• Corrosion or hairline cracks visible on the valve body
• Tank emptying too slowly or incompletely
CountBricks surfaces real-time material prices every time you speak with our AI estimator, but home-owners like to start with benchmarks:
• Basic universal plastic valve kit: $10 – $22
• Premium adjustable dual-flush kit: $28 – $45
• Professional plumber labor (Portland residential rate): $90 – $140 per hour
• Average total project cost: $110 – $185 per toilet
Because CountBricks tracks supplier feeds 24/7, these numbers update automatically inside your estimate, ensuring you never rely on outdated price books.
• Toilet type and age: One-piece and wall-hung units require more disassembly, adding 15 – 30 % labor.
• Access and shut-off condition: Corroded supply valves may need replacement, increasing material cost by $12 – $25.
• Water quality: Hard-water areas often call for premium silicone seals that resist mineral buildup.
• Permit requirements: Simple replacements rarely need a permit, but multi-unit buildings might have inspection fees.
Replacing a flush valve is considered an intermediate DIY task. If you are comfortable shutting off water, draining the tank, and loosening tank bolts without cracking porcelain, you can likely complete the work in under an hour.
• Universal kit purchase: $12 – $25
• Required tools (if not already owned): Adjustable wrench, channel-lock pliers, flat screwdriver, shop towel
• Total out-of-pocket: $15 – $45
• Trip fee or minimum 1-hour labor: $90 – $140
• Mid-range kit supplied by contractor: $25 – $35
• Hazard disposal and clean-up included
• Total: $115 – $175
