Every toilet tank has only a few components that can fail and cause the toilet to stop operating properly: the flush valve, and the fill valve. If there's a failure with the flush valve, it's possible that the attached rubber flapper has worn off or isn't sitting properly in the opening.
The two main parts of the toilet are the tank at top and the bowl at bottom.
To troubleshoot your toilet, pour three gallons of water into the bowl. If the water does not go down within the first couple of seconds, your problem is a clog blocking the flow. This can be fixed by using an auger to break up the blockage.
If you have a toilet that doesn't fully flush, common causes include a clog in the trap, a worn-out flapper, blocked rim jets, a faulty float, or an issue with the handle and chain.
Warning signs that your fill valve is bad are the constant sounds of running water from the tank and an ineffective flush. You can troubleshoot by adding a few drops of food coloring to the tank. If you do not see the food coloring leak into the bowl, then the fill valve needs to be replaced.
A running toilet is typically caused by the overflow tube, flush valve, or fill valve. Check the water in the tank to determine if it is running into the overflow tube. If the water is running into the overflow tube, the water level might be too high or the overflow tube might be too short for the toilet.
THE TOILET BOWL
The bowl is the most important part of the toilet, as its simplistic yet genius design allows for easy waste disposal, using a siphon.
What is the average cost for a new toilet? The cost of a new toilet varies widely depending on the brand and features, but typically averages $200 to $500. Professional installation will increase the total cost to around $400 to $800.
The most likely cause is capillary action. This happens when a piece of debris, wicks the water out of the bowl and down the drain. It could be something as small as a string. Another possibility is the drain venting in the home is not sized properly, or a clogged vent.
A constantly running toilet is one sign of a worn-out flapper. To test your flapper's performance, put a few drops of food coloring into the tank water. Don't flush the toilet. If after 30 minutes you find colored water in the toilet bowl, replace the flapper yourself or call a plumber to do the job for you.
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.
The toilet's flush valve will typically last 6-7 years. A toilet fill valve might only last four to five years. In general, you should expect to replace the parts in your toilet every so often while keeping the actual bowl in place.
The most common cause behind a running toilet is by far a broken toilet flapper. Also known as the flush valve, this plug holds water inside the tank until you use the toilet's handle to flush the toilet bowl. Unfortunately, flappers wear down over time, causing water to seep slowly into the bowl.
Running Water
A toilet that won't stop running is another common problem. You can expect to pay between $50 and $400 to repair a running water issue. If there is too much water in your tank, it will be a quick, easy fix and may be possible to do at home.
This problem is almost certainly caused by a bad flapper or flapper seat. The solution is to drain the tank and bowl, check and clean the flapper seat and then replace the flapper if it's worn or damaged.
Will a running toilet stop eventually? As fresh water enters the tank, a mechanism eventually shuts off the water flow and the toilet will stop running. However, when things go wrong with the valve, flapper or overflow then it's best to get it sorted.
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.
There are really only two main toilet tank parts: The toilet flush valve, which lets water gush into the bowl during the flush, and the fill valve, which lets water refill the tank after the flush. When a toilet runs constantly or intermittently, one of these valves is usually at fault.
