How Much Is a Running Toilet Costing You?

Covenant Plumbing is your trusted local plumbing & drain experts in Bloomington-Normal, IL. and the surrounding areas since 2006.

Toilets are often the biggest culprit of high water usage. Sometimes they continue flowing water because the flapper sticks, the chain is caught on something inside the tank, or parts are worn out inside the tank. 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 for just one leaking toilet! What does all that cost? We’ve had customers estimate that they had additional water bills of $50-$200. For Delayne and I personally, we had a toilet in the basement of our first home that would stick when flushed. We had a $250 water bill one month because we went away for the weekend and it ran the whole time we were gone!  That’s a big ouch when you’re young and poor. And it also taught us to listen to our toilets a little more closely.

Some toilets may produce a running water sound that is easy to hear. Some leaks are visible as a small trickle running from the rim to the water in the bowl. Toilet leaks are often silent and can be intermittent, allowing loss of water to go undetected for long periods of time. To detect silent leaks, remove the lid from the toilet tank, remove any colored or bleaching cleaning agents. Flush to clear the water in the bowl. Then add dye tablets, leak detector fluid, a few drops of food coloring, or a colored instant drink mix to the toilet tank. If there is a leak in the toilet, the color will appear in the bowl within 60 minutes. Flush the remaining color from the tank as soon as the test is complete.

If you have a toilet that is causing problems, our plumbing experts are here to help. Call us at to schedule an appointment

Covenant plumbing was prompt, professional, and did a beautiful job replacing the shower faucets. They also installed a water filtration system for the house, which was definitely needed. As always, their work is the highest quality, and we look forward to enjoying it for years to come.

I’ve used Covenant Plumbing twice now, Amanda in office is so kind and goes above and beyond in ensuring good communication. Every technician has been amazing, I’ve dealt with a host of issues after buying an old home and they’ve always been transparent and done excellent work. Very trustworthy, I wouldn’t go anywhere else!

The crew that came out really went above and beyond in identifying and repairing the issue with our sump line. Their extra diligence found not only one problem, but another more severe issue further down that could have turned into a much larger problem, had they not caught it.We have nothing but good things to say about our various experiences (current and previous) with Covenant. Thorough, professional and skilled all around!

Delayne and his son were very professional and friendly. Delay e quickly identified the problem with our garbage disposal and since it was under warranty, replaced the disposal with same make and model. They completed the job quickly and efficiently. Highly recommend Covenant Plumbing!!

Jordan was great!!! As a homeowner, I try to complete small DIY projects myself. Jordan took a look at the work that I’d done to make sure it was complete and proceeded to repair a fill valve that I didn’t care to tackle, lol. He was great and even explained to me the steps to take if I should have any future concerns. Definitely keeping their number in my contacts of preferred plumber :)

Shane was easy to work with. Explained how the new RO system would be installed and where the new filters would be placed in the basement. Went over the pricing of each item to be installed, including the garbage disposal unit. Nice to have someone willing to take the time and effort to go over all the details with the customer!!
