Do you know 27% of your home’s water use comes from just flushing the toilet?

Each person averages five flushes per day at home, according to Conserve H2O — or 20 flushes per day for a family of four.

Every flush costs money, and they can really add up.

But we found an easy tool to cut your toilet’s water use — and cost — almost in half.

How Much Does It Cost to Flush Your Toilet?

Toilets have come a long way in recent decades, but a lot of homes are still equipped with old, inefficient systems that waste money.

If your toilet was made before 1994, it probably uses between 3.5 and 7 gallons of water per flush. Even newer toilets use up to 1.6 gallons.

So your family could be flushing up to 140 gallons of water down the toilet every day.

Between average water and sewer rates, you’ll pay about 0.3 cents per gallon.

At 3.5 gallons per flush, your family is paying about $76.65 per year just to flush the toilet.

Not everyone has the option to replace the old john, and some of us aren’t too keen on the “let it mellow” rule to save water.

Reduce Water Use Without Buying a New Toilet

An easy way to reduce the amount of water you use — and the cost of it — is to minimize the amount of water needed to fill the tank after each flush.

You can do so by putting something in the tank to take up space.

The Tank Bank is a tool made for that exact purpose. It clips onto the side of your toilet tank and displaces approximately 0.8 gallons of water per flush.

Clip two Tank Banks inside your toilet tank to save 1.6 gallons of water per flush, and you’ll save $35.04 — or 46% — on your water bill every year.

A pack of three Tank Banks is just $12.99, and they never need to be maintained. Click below to buy yours now, and continue to save money year after year.
