Faucet Leak Detection & Repair in Beaverton, OR

Faucet leaks are the most visible plumbing problem in any Beaverton home -- a dripping kitchen or bathroom faucet announces itself with every drop. What is less obvious is the cumulative water waste: one drip per second loses approximately 3,000 gallons per year at TVWD rates, adding roughly $18-$22 to an annual water bill. A faster drip -- which many homeowners characterize as "not that bad" -- can reach 6,000-10,000 gallons of annual waste. The repair cost is almost always lower than one year's worth of the wasted water charge.

Beyond the visible drip at the spout, faucet-related leaks also develop at the supply connections under the sink -- the braided stainless or chrome-plated supply hoses that connect the shutoff valves to the faucet body. These under-sink connections are rarely inspected until a problem appears, and a slow weep from a supply hose can saturate the cabinet base, rot the sink cabinet floor, and eventually reach the subfloor before anyone notices. The supply hose failure at a kitchen sink is a common source of the cabinet-under-sink mold problem we find in older Cedar Hills and Murray Hill homes during bathroom or kitchen updates.

Faucet Failure Types in Beaverton Homes

Ball faucets (single-handle, common in kitchens): The rotating ball mechanism controls both hot-cold mixing and flow volume. Internal O-rings, springs, and seats wear over time. Drips at the spout indicate worn seats or springs; leaks at the handle base indicate failed O-rings. Beaverton's soft Bull Run water does not leave mineral scale on ball faucet components the way hard-water supplies do -- which can actually allow mineral-scale-induced wear to go unchecked longer than in harder-water cities.

Cartridge faucets (single or double handle, very common in bathrooms): A cartridge slides to control flow and temperature. Cartridge O-rings and the cartridge body itself wear with use and age. Drips at the spout when the faucet is off indicate a failed cartridge that cannot fully close. These are typically straightforward repairs -- the cartridge is removed and replaced with a matching unit.

Compression faucets (two-handle, older installations in pre-1980s Beaverton homes): A rubber washer compresses against a seat to stop flow. Worn washers produce the classic slow drip. Central Beaverton, Vose, and older Raleigh Hills homes with original bathroom fixtures from the 1960s-1970s may still have compression faucets. Replacement washers cost under $1; valve seat corrosion that prevents a new washer from sealing requires reseating or replacement of the valve body.

Ceramic disc faucets (single lever, wider body, newer installations): Two ceramic discs control flow and temperature through precise alignment. They are extremely durable but not immune to failure -- the discs can crack, and the inlet seals degrade with age. Unlike other faucet types, ceramic disc failures are often an intermittent rather than constant drip, making them harder to diagnose by feel alone.

Supply Connection Leaks at Kitchen and Bathroom Sinks

Under-sink supply connections are the second most common faucet-adjacent leak source in Beaverton. The flexible supply hoses connecting shutoff valves to the faucet body fail through: hose aging and cracking (braided stainless hoses have a 10-15 year service life), compression fitting failure at the shutoff valve or faucet connection, and corrosion at the shutoff valve body itself. We inspect under-sink connections for early signs of failure -- corrosion at fittings, moisture staining on cabinet walls, or white mineral deposits from historic drips -- on every faucet assessment call.

For faucet repair and under-sink supply connection assessment in Beaverton and Washington County, call (503) 974-3329. We also handle faucet leaks that have already caused under-sink cabinet damage -- see our sink leak detection page for damage assessment scope. Homeowners in Cedar Hills and Raleigh Hills with older two-handle compression faucets should consider proactive assessment as original fixtures approach 50 years of service.
