That Dripping Faucet Is Costing You More Than You Think

The real cost of one drip

A faucet dripping at the rate of one drip per second wastes about 5 gallons per day. Over a month that's 150 gallons. Over a year, roughly 1,800 gallons wasted — plus the energy to heat it if it's a hot-water drip. In Fort Worth, with current water and sewer rates, that one dripping faucet costs the typical household $15–$40 per year in water bills plus another $20–$60 if it's a hot drip.

Not catastrophic — but not nothing. And the actual fix is usually $10 in parts and 20 minutes of work. Ignoring a drip is paying $35 a year to avoid a 20-minute repair.

Why faucets drip in the first place

Modern faucets have one of three internal mechanisms: compression (old-style, two-handle), ball-type (single-handle Delta classic), or cartridge/ceramic disc (most modern faucets). All three fail in the same general way — a rubber or plastic seal inside the faucet wears out, and water sneaks past it. Hard water in Fort Worth accelerates this because mineral deposits abrade the seals and the surfaces they seal against.

For 90% of dripping faucets, the fix is replacing the internal cartridge (modern faucets) or the rubber washers and O-rings (older compression faucets). Parts cost $5–$25. Repair labor if you call a plumber: $150–$250 depending on the faucet type.

The hidden damage a slow drip causes

Beyond the water bill, a slow steady drip does three kinds of damage:

• Mineral staining on the fixture itself. Every drop deposits a tiny amount of calcium and magnesium (hard water). Over months, that builds up into visible white or green deposits that are hard to clean off and sometimes etch the finish permanently.
• Slow erosion of the sink or tub surface. Where the drops land hundreds of thousands of times, the surface slowly wears. On porcelain, this can show up as a visible groove or dullness. On stainless, as a water-stain pattern that won't buff out.
• Mold growth. If the drip lands in a spot that stays damp — a shower drain that doesn't fully clear, a sink that holds a puddle — you get mold spots that are easy to miss until they're established.

The DIY fix for most faucets

For a modern single-handle cartridge faucet:

1. Shut off the water at the two valves under the sink.
2. Open the faucet to drain any water in the lines.
3. Remove the handle. Usually one hex screw under a decorative cap on the top of the handle or on the side.
4. Underneath the handle, you'll see a retainer nut or clip holding the cartridge. Remove it (slip-joint pliers usually enough).
5. Pull the cartridge straight up and out. Note its orientation.
6. Take the old cartridge to a hardware store. Buy an identical replacement (brand name helps — Moen, Delta, Kohler all have different cartridges).
7. Install the new cartridge in the same orientation. Reassemble.
8. Turn water back on. Test.

Total time: 20–30 minutes. Parts: $15–$30. If it works, you just saved yourself $150+ and solved a problem that was quietly costing you money every day.

When the DIY fix isn't enough

• Faucet still drips after cartridge replacement — usually means the faucet body itself is worn (seat damage, pitted internals) and the whole faucet needs replacement
• Faucet handle is seized and won't come off — stripped screw or corrosion
• Water pressure drops dramatically after the fix — debris got into the lines during disassembly
• Multiple drips in multiple faucets at once — may be a water pressure issue (PRV failing) rather than individual faucet problems
• Shower faucet (vs. sink) — showers have more complex internals and are harder DIY jobs

When replacement makes more sense than repair

If the faucet is 15+ years old, the finish is corroding or pitted, the base is wobbling in the sink, or you've already replaced the cartridge once in the past 2–3 years — stop fixing it. A quality replacement faucet is $80–$300 and installation is 30–60 minutes. Over its 15–20 year lifespan the new one will cost you less than continuing to repair the old one.
