How to fix leaking toilets before your household savings go down the drain

Never go on vacation without checking your toilets, first! We did, and boy, do we regret it! Did you know that the average American goes through 80-100 gallons of water per day, and our greatest use comes from flushing the toilet? And, a leaking toilet can waste up to 200 gallons of water a day, according to the U.S. EPA . In our four-person household, we have three toilets, and two of them sprang leaks while we were gone!

We returned from a three-week vacation to gurgling toilets and a call from the Board of Water Supply–-they’d just read our meter and the dial was moving, which indicated a leak. Plus, our water consumption had spiked six times higher than normal.

I got that sinking feeling. Up until we left, our two toilets had shown an occasional tendency to keep trickling, post-flush, until we’d lifted the tank lid and adjusted the rubber flapper valve to stop water flowing out. Just before leaving, we checked to make sure the toilets weren’t running.

But things can happen while you’re gone. Plumbing is unpredictable and spontaneous flushes. Well-meaning family members who stopped by to check on things in our absence didn’t check the toilets after flushing. Leaks get worse, fast.

“Exactly how much higher was our water use?” I asked.

There was a pause as she checked, followed by a half-strangled cry: “Your average water use in each two-month billing cycle is 27,000 gallons, but this time, you used 176,00 gallons!”

If you have ever fallen flat from the top of the jungle gym and knocked out all your air, you will know how I felt. Twenty-seven thousand gallons was bad enough–-we’d been trying to conserve by taking shorter showers (second highest indoor water use), but we should have tackled the toilets first! Our plumbing had been leaking four gallons a minute, the water rep said.

I did the math. Indeed, four gallons a minute added up to over 170,000 gallons in just 30 days, and ours was a 60 day bill. “Er, does that mean my water bill will be seven times higher?” I asked.

The answer was yes. Hello to the $1,350 water bill! Goodbye, in one fell blow, to our painstakingly accumulated household savings! Worse, all that precious clean drinking water had gone down the toilet!

“You’re not alone, this happens all the time,” the water rep said. “We had an old toilet out back we never used. Turned out it was leaking for three weeks, and our water bill tripled!”

Misery doesn’t love company in this case. Americans use 410 billion gallons of water a day, according to The Ripple Effect: The Fate of Freshwater in the Twenty-First Century. In his compelling new book, Alex Prud’homme reports on water science and politics, with stories of people and neighborhoods faced with clean water shortages due to pollution, privatization, droughts and waste.

While industry and agriculture are the biggest culprits by far, an estimated trillion gallons of water are lost in U.S. home leaks every day. This, at a time when global clean drinking water supplies are shrinking due to industry, agriculture, urbanization, and drought and sea level rise linked to climate change, as Prud’homme reports in harrowing detail. “Borrowing from the notion of peak oil–a point at which the supply of oil is outstripped by human consumption--academics worry that the earth could be reaching a point of ‘peak water,” he warns.

I’m worried, too! But at least, now that we’ve fixed our leaks, I don’t have to worry about being such a huge part of the problem.

What You Can Do

*Be on the alert for trickles and drips.

If your toilet keeps flowing for longer than a minute after a flush, it means the flapper valve is not closing, so the tank never fills.

*Fix leaks right away. Here's how:

Step 1. Both our toilets had worn-out rubber flappers (see round red cap in photos, above) which no longer sealed the drain, so the tank kept filling...

Note the model number on inside wall of tank, go to hardware store and buy new flapper.

Step 2. One toilet also had a worn-out gasket inside the float. The result: The float didn’t rise with the water level, so the flapper, at the other end of the lever, never fully closed.

*Reduce tank capacity.

In our 1.6 gpf toilet, we moved the lever on the float down so that the tank only fills half full.

In the old 3.5 gpf tank, I set two filled glass quart bottles (a total half-gallon), which will save 4,000 gallons a year until we replace that toilet.
*Consider buying an efficient toilet.

If your toilet is older than 1992, it’s likely using 3.5 gallons per flush (gpf). Since 1995, the federal standard is 1.6 gpf.
An EPA-approved Water Sense toilet uses an average 1.24 gpf.

*When you go on vacation, shut the water off.
The exception: If you've got a garden that needs watering. And note, if you turn off your household water valve but if you leave the electricity on, remember to turn off the hot water heater!
