Your toilet is running because the water isn't sealing properly in the tank, usually due to a worn-out flapper, an improperly set float, a problem with the fill valve, or the water level being too high and spilling into the overflow tube. The most common fixes involve adjusting the float, replacing the flapper, or cleaning mineral buildup from the seals.
Here are five common causes of a running toilet and how to resolve them, with expert tips straight from the field.
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.
A blocked drain line creates pressure that leads to air bubbles during a flush. Using a plunger might clear a minor clog, but if the blockage is deeper in the system, you might need a plumber's snake to clear it.
STEP 1: Turn off your water supply at the mains. STEP 2: Turn on every tap in the house, starting at the top and working your way downstairs. STEP 3: Wait for the water to stop flowing out of the taps. STEP 4: Now flush all the toilets until no water is left there either.
No matter when you hear it, a hissing toilet is not something to ignore. The hissing typically indicates that water is continuously running somewhere it shouldn't be, which can lead to a host of problems, including shockingly high water bills and potential water damage.
Water running in a toilet constantly is usually a sign that there's a leak or toilet repair issue. And the longer you put it off, the more damage can occur.
What causes a running toilet, and how can it impact my water bill? A running toilet, often due to a leaky flapper valve or a faulty fill valve, can significantly increase your water bill. Continuous water flow from the toilet tank to the bowl wastes gallons of water, leading to higher costs.
A constantly running toilet can waste up to 200 gallons of water per day, potentially costing $50-$100 or more per month in excess water usage. The exact cost depends on local water rates and the severity of the leak, but fixing the issue promptly is crucial to avoid significant water waste and high bills.
You should never flush wet wipes (even "flushable" ones) and sanitary products (like tampons/pads) because they don't break down, causing serious blockages in pipes and sewage systems. Other items to avoid include paper towels, tissues, cotton buds, dental floss, hair, and cooking oils/fats, as they all contribute to clogs and environmental issues.
Inspecting your toilet tank components
Fixing a running toilet can be a feasible DIY project, but in most instances, it's wiser to enlist the help of a professional plumber.
Problems That Can Wait For The Plumber
For example, if you have a persistently running toilet, it might keep you up with its incessant noise. But as long as it's not overflowing, you can probably hang tight until morning before calling for help.
Not literally, of course – but your water bill will skyrocket if your toilet is constantly running. More often than not, continuously running toilets are extremely easy and inexpensive to fix – you might just need to replace the flapper. A constantly running toilet also presents an increased risk of flooding.
The aluminum foil ball trick works primarily through water displacement. When you place objects in your toilet tank, they take up space that would normally be filled with water, reducing the amount of water used with each flush. Think of it like dropping rocks into a glass of water.
Persistent Leaks
If your toilet leaks continuously despite repeated DIY fixes, it's time to call a professional. Persistent leaks often indicate deeper issues that require a plumber's expertise to identify and resolve.
While certainly annoying, a toilet that runs continuously can also be costly in many ways. From a huge water bill to potential flooding or a damaged septic system, running toilets are often more than just a nuisance.
A running toilet is typically caused by one of five different factors that can be easily narrowed down with some good old fashioned process of elimination:
A leaky toilet can be a massive contributor to a high water bill. We have seen continuously running toilets use 20,000 to 30,000 gallons of water in a month. A dripping leak consumes 15 gallons per day and 450 gallons per month. A 1/32 inch leak consumes 264 gallons per day and 7,920 gallons per month.
The most common cause for a high water bill is running water from your 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.
If you hear gurgling sounds from your toilet when it's not in use, this could signal a blockage in the vent pipe or a problem with the sewer line. Such issues often require a professional plumber to resolve, as they can lead to more severe complications if left unaddressed.
The average toilet fill valve replacement cost is $60 to $150 (CAD 83 to CAD 208), with most homeowners paying approximately $125 (CAD 173). However, it's important to note that these are average costs, and your plumber may charge more or less based on their own parts and labor rates.
