How Much Water Does a Dripping Faucet, Dripping Shower Head or Running Toilet Waste?

How Much Water Does a Dripping Faucet Waste?

Quick answer: A faucet dripping about once per second wastes roughly 5 gallons of water a day, which adds up to more than 2,000 gallons a year, and the EPA estimates the average household’s leaks can waste nearly 10,000 gallons annually. One slow drip seems harmless, but it runs your water bill up 24 hours a day and can point to a worn part that only gets worse.

The exact amount depends on how fast the faucet drips. Here is what common drip rates add up to, based on standard industry estimates.

Dripping Faucet Water Waste by Drip Rate

Drip rate Wasted per day Wasted per year
10 drips per minute about 1 gallon about 350 gallons
30 drips per minute about 3 gallons about 1,040 gallons
1 drip per second (60 per minute) about 5 gallons about 2,080 gallons
2 drips per second about 11 gallons about 4,000 gallons

These figures line up with the drip calculator published by the American Water Works Association (AWWA), the industry reference for water use: one drip per second works out to about 5 gallons a day and just over 2,000 gallons a year.

What a Dripping Faucet Costs You

At a typical local water and sewer rate, a single steady drip can add several dollars to your monthly bill, and more than one dripping fixture multiplies that fast. The bigger risk is what the drip signals: a worn washer, O-ring, or cartridge that will keep failing, or a valve problem that can turn into a real leak. Fixing it early is cheap. Ignoring it is not.

How to Stop a Dripping Faucet

Most drips come from a worn washer, O-ring, or cartridge inside the faucet, and they are a quick, inexpensive repair for a licensed plumber. If the drip returns after a repair, or you see water under the sink, the valve or supply line may need attention. Earl’s Plumbing fixes dripping faucets across Metairie, Kenner, and New Orleans, usually in a single visit.

Frequently Asked Questions

How many gallons does a dripping faucet waste per day?

A faucet dripping about once per second wastes roughly 5 gallons per day, or about 2,080 gallons per year. A faster drip of two per second wastes around 11 gallons a day, close to 4,000 gallons a year.

Does a dripping faucet increase my water bill?

Yes. A dripping faucet runs continuously, so it adds to your water and sewer bill every single day. One drip is usually a few dollars a month, but multiple dripping fixtures or a faster drip add up quickly, and the underlying part will keep failing until it is repaired.

Is a dripping faucet worth fixing?

Almost always. The repair is usually a low cost washer, O-ring, or cartridge replacement, and it stops the wasted water and the rising bill immediately. It also prevents a small drip from becoming a bigger leak that damages your cabinet or floor.
