A leaky faucet is one of those problems that's easy to ignore — until it isn't. That slow drip in the kitchen or the trickle from your bathroom tap can waste thousands of gallons of water a year and quietly drive up your utility bill. If you're a homeowner in El Dorado or anywhere in Butler County, knowing what causes a leaky faucet and when to fix it yourself versus when to call a plumber can save you real money.
Here's a straightforward breakdown.
What Causes a Leaky Faucet?
Most faucet leaks come down to a handful of common culprits:
Worn-Out Washers
This is the most common cause in traditional compression faucets. Every time you use the faucet, the rubber washer presses against the valve seat. Over time, friction wears it down and water starts sneaking through even when the handle is off.
Damaged O-Rings
Cartridge faucets use O-rings — small rubber seals — to keep water from leaking around the stem. When these crack or loosen with age, you'll often see dripping near the handle rather than the spout.
Corroded Valve Seat
The valve seat connects the faucet and the spout. If sediment builds up there — which is common with the mineral content in Butler County well water — the seat corrodes and leaking starts at the spout.
Loose Packing Nut
If water is seeping from around the handle stem, the packing nut may just need to be tightened. This is one of the easier fixes.
Worn Ceramic Disc
Ceramic disc faucets are more durable, but the discs themselves can crack or the seals can degrade, especially if your water has high mineral content.
Can You Fix It Yourself?
Sometimes, yes. Here's what a basic DIY faucet repair looks like:
- Turn off the water supply — look for the shutoff valves under the sink.
- Turn on the faucet to release any remaining pressure.
- Remove the handle — usually held by a screw under a decorative cap.
- Inspect the cartridge, washer, or O-ring depending on your faucet type.
- Replace the worn part — take the old part to a hardware store to match it exactly.
- Reassemble, turn the water back on, and test.
If that sounds manageable, it can be a solid Saturday-morning fix. A replacement washer or O-ring costs almost nothing, and the job typically takes under an hour for a standard faucet.
But there are limits to what DIY can handle.
When to Call a Plumber in El Dorado
Some faucet leaks are symptoms of a bigger problem. Call a licensed plumber if:
- The leak comes back after you've already replaced the washer or cartridge
- You can't identify the source — sometimes what looks like a faucet drip is actually a supply line or fitting behind the wall
- The faucet is corroded or stripped and parts won't come apart cleanly
- Water pressure seems low throughout the house alongside the leak — could indicate a pipe issue
- You're dealing with well water and seeing rust or mineral buildup — that can complicate repairs and signal bigger water quality problems common in rural Butler County homes
Our plumbing repair services cover everything from basic faucet fixes to full supply line diagnostics. We work with both city-water homes in El Dorado and well-water properties throughout the surrounding area.
How Much Does Faucet Repair Cost?
A simple washer or cartridge replacement from a plumber typically runs between $75–$150, depending on the faucet type and accessibility. Full faucet replacement — if the fixture itself is shot — usually lands between $150–$350 including parts.
That's a lot less than what a neglected leak costs over time. A faucet dripping once per second wastes over 3,000 gallons per year. In El Dorado, where water rates are manageable but not zero, that adds up.
We also offer financing options if you're dealing with multiple plumbing issues at once and want to handle everything in one visit.
