A dripping faucet costs $3-$20 per month in wasted water
A single faucet dripping once per second wastes 3,000+ gallons yearly, adding $35-$250 annually to water bills. Costs depend on leak severity, local water rates, and hot water usage (which also wastes energy). Fixing it early prevents higher expenses and potential plumbing damage.

Hidden Costs Beyond Water Bills
- Hot water leaks: Add $5-$30/month in energy waste (water heater reheats unused water).
- Plumbing damage: Long-term drips corrode fixtures, requiring $100-$500+ in repairs.
- Mold/mildew: Moisture buildup near sinks may lead to $200-$1,000+ in remediation.
- Higher sewage fees: Some municipalities charge for water and wastewater volume.
How to Calculate Your Exact Cost
- Measure the drip rate: Count drips in 1 minute, then multiply by 1,440 (minutes/day).
- Convert to gallons:
- 1 drip = ~0.00013 gallons (standard faucet).
- Example: 60 drips/minute × 1,440 × 0.00013 = 11.2 gal/day.
- Check your water rate: Find cost per gallon on your utility bill (average: $0.003-$0.01/gal).
- Multiply:
(Gallons/day × 30) × cost/gallon = monthly cost.

When to Worry: Signs of a Serious Leak
