A clog is the most common reason for a toilet that doesn't flush. Clogs can range in severity, from a complete blockage to a partial obstruction. Wipes, toilet paper and other items can build up in sewer lines, which could result in slow flushing that doesn't completely clear the bowl.
If water is constantly running down the overflow tube, the fill valve needs to be adjusted. Turning the adjustment screw on the valve in one direction raises the water level and the other direction lowers it. The ideal level for a toilet tank is about an inch below the top of the overflow tube.
Check the water level in your tank. The water should come up to about one inch below the overflow tube. If the water level is too low, double check the water valve to make sure the toilet is receiving water. If this doesn't help, check for problems with the flapper, float, fill valve, and refill tube.
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.
On average, most toilets will have a lifespan of between 10 and 15 years, even with regular use. The lifespan may vary depending on the toilet model and the wear and tear it experiences over the years. Most toilets will start to give you warning signs indicating the time for replacement is near.
An occasional repair is normal, but if you're constantly having to fix toilet issues, that can become a costly and time consuming problem. One or two toilet issues is to be expected, but if you are frequently and consistently running into the same problem, or even multiple problems, a new toilet is the way to go.
Place a few drops of food coloring into the tank and watch to see if the colored water leaks out into the bowl. If no food coloring enters the bowl, your fill valve is causing the running water. Replacing a faulty fill valve will reduce your water consumption and restore your toilet's flushing capabilities.
According to the United States Geological Survey, a leaking toilet that is allowed to run continuously can waste up to 22 gallons of water a day. If allowed to run a full year, that's a leak that amounts to over 8,000 gallons of water. The impact is multiplied for each leaking toilet in your facility.
The Flapper Is Leaking and Needs Replacing
Perhaps the most common reason for a running toilet is an old flapper that needs to be replaced. When flappers get old, they don't seal the way they should, and this allows water to pass constantly from the toilet tank into the bowl.
According to Fixr, the average toilet valve repair cost is between $75 and $200 to replace a flush valve or up to $400 to fix a constantly running toilet. This includes the cost of the plumber's time for the toilet repair and the cost of the toilet parts.
According to data from Porch, you can expect to pay around $310 for a valve and stem replacement, or slightly more if you replace the whole unit. Fees for replacing the whole shower valve can be as high as $540, with this price including the cost of the unit and labor.
More often than not, the flapper valve could need adjustment, or you may need to replace the toilet fill valve. Both are relatively small fixes that most homeowners can usually handle without calling in a professional plumber or having to remove the toilet and then having to install a new one.
If there's one household fixture we really rely on and hate to have to fix, it's the toilet. But while these fixtures are prone to acting up now and then, the good news is many common toilet repairs are do-it-yourself-friendly; few (if any) basic hand tools are required to fix a toilet.
Irregular Running Water
Check that your toilet tank ball falls onto your valve seal. If it lands off-center or doesn't connect at all, you need to replace the valve. To fix this problem, a plumber will need to remove the defective tank ball and then put the new valve in place.
While your old toilets may technically do their job, they're simply not as efficient as newer models. Not to mention if your old toilets start to show their age by cracking, leaking, or clogging, it's often best to consider toilet replacement rather than repair.
According to the Energy Policy Act of 1992, toilets installed after 1994 must have a flush volume of 1.6 gallons per flush. Toilets manufactured before this policy went into effect used between 3.5 to 5 gallons. The bottom line on aging toilets? If you know your toilet is at least 25 years old, consider replacing it.
If your toilet isn't flushing all the way, it's most likely because of one of these problems: The water level in your toilet tank is set too low. Problems with your flapper. A clog in the toilet, flange or drain.
Q: How long does a toilet flush valve last? Flush valves will commonly wear out before your toilet, lasting on average between six and seven years, depending on the quality of water, frequency of toilet use, and whether you've used harsh chemical cleaners.
If a toilet is in perfect condition but does not fill up with water after flushing, you probably have low water pressure. Old rusty pipes and leaking pipes are the most common causes of low water pressure in homes.
