Since the water flows down the sewer, leaking toilets don't necessarily leave any signs of a leak, until you get the bill. The average leaky toilet can waste about 200 gallons of water per day. That's over 6,000 gallons a month ($70.06*) for just one leaking toilet!
A continuously running toilet can waste up to 200 gallons a day or more depending on the volume flow down the drain. This can cause a terrible increase to a family's typical water use, so fix toilet leaks as soon as possible. Some leaks are easy to find, such as a dripping faucet or running toilet.
Depending on the water pressure to your house, a running toilet can leak over one gallon of water per hour. This is almost one unit of water a month. If left undiscovered, a running toilet can waste almost 13 units of water a year. Fortunately, most toilet leaks are relatively easy to fix.
So that's 1.5 gallons per flush or per 30 seconds, or 3 gallons per minute. For all 1,440 minutes per day, that is up to 4,320 gallons of wasted water! If you left your leaky toilet running this way for an entire week, you'd waste 30,240 gallons of water.
If your toilet bowl is leaking, it's smart to turn off the water at the shutoff valve. You will usually find it behind your toilet.
How Long Can You Turn Off Water to a Toilet? Like turning off your toilet's water for a night, it's safe to do so for a week. While you can keep your toilet water off for as long as you'd like, we wouldn't recommend it unless you have a problem with your toilet's plumbing system.
Leaking Around the Base of Your Toilet
The worst-case scenario is that the toilet leaks through the floor and causes damage to the room underneath. For this reason, it's best to involve a plumber to pinpoint the cause of the toilet leak and provide a quality solution.
One of the worst culprits for wasting water in your home or business, a toilet with minor leaks, can add an additional $1,000 a year to your water bill. A toilet with major leaks can cost an extra $2,000 annually!
It costs between $150 and $300 to fix a leaking toilet in most cases. The cost would be a lot more if the leak has caused damage to your floor or if it's a recurring problem.
A leaky faucet that drips at the rate of one drip per second can waste more than 3,000 gallons per year. That's the amount of water needed to take more than 180 showers!
Typically, a running water toilet will waste thousands of gallons of water per month which translates to approximately $200 unnecessarily tacked onto your monthly water bill-- that's nearly $2,500 dollars a year down your toilet bowl. The above scenario is in the case of an extreme toilet leak.
A constantly running toilet also presents an increased risk of flooding. This risk can come in a few forms. When you have a septic tank, excess water can go over the tank's capacity, which can lead to sewer backups and basement flooding.
Loose or worn out tank-to-bowl connections.
The tank and bowl in two-piece toilets are bound together by a collection of gaskets, nuts and bolts. If any of these parts come loose, a leak can develop at that area in the toilet.
Your water and sewer bill could double or even triple in a quar- terly billing cycle. About 20 percent of all toilets leak. Most toilet leaks occur from the tank on the back of the toilet into the bowl, and then into the sewer. They might not make much, if any, noise.
A leaky toilet might not seem like a huge problem, but the water can quickly damage the bathroom walls and floor. External leaks can cause water puddles that can damage a downstairs ceiling, while internal leaks prevent the toilet from holding water properly.
The most common toilet leak is caused by a deteriorated flush valve (flapper) at the bottom of the toilet tank. If the flapper does not seat properly, water will leak into the toilet bowl. Often this leak will occur without being heard.
While leaky sinks and pipes can cause damage to your home, there's a vast difference between a tiny leak that's dripping and a considerable leak that quickly fills buckets of water. A large volume of leaking water is generally considered a plumbing emergency.
Bathrooms: High efficiency toilets use 1.28 gallons per flush or less, non-efficient toilets use up to 5 gallons per flush. A silent toilet leak can be as small as 30 gallons per day (GPD). Larger leaks can be up to 6 gallons per min, equivalent to 11 billing units (BU) per day.
Assuming each flush uses 1.5 gallons and that you skip the flush three times a day, that amounts to around $2.95 saved each year. Now, this will vary from state to state and even city to city. For instance, if you live in Florida, your savings will likely be much lower because water costs less.
According to SFGate, flushing the toilets accounts for a whopping 30% of the average household's water usage. Therefore, reducing the amount of water flushed away every time you visit the bathroom is an effective way to lighten the load on your wallet.
While toilets are meant to last several decades, they do have a limit. If you know your toilet has been around longer than you've been alive, then there's a chance that it's likely on its last leg already. A general rule of thumb is to replace a toilet around every 25 years, though your mileage may vary.
Sewage backup
While a leaking toilet may be covered by your homeowners insurance policy, a flooded or backed-up sewage system is not covered, even though it may overload your plumbing system.
There are likely a couple of reasons the water in your toilet won't stop running. It could be a leaky flapper or a bad fill valve. The good news is you don't have to call a plumber, these are all easy fixes you can do yourself for little money.
