Reasons Your Toilet Won't Flush & Ways to Fix It!

Few things are as embarrassing as a toilet not flushing all the way. Even if there are several toilets in the house, it's a situation that needs a quick fix. However, homeowners are often unaware of why a toilet won't flush: it could be clogged, not getting enough water, or some parts need to be replaced. Fortunately, some of these are problems that you can solve yourself!

In this article, we look into why your toilet won't flush and share some quick plumbing fixes you can try yourself—if you're up for it!

How to fix a toilet that won't flush? Read on to find out!

How to Fix a Toilet that Won't Completely Flush

Why is My Toilet Not Flushing?

It's not a question that anyone wants to ask themselves, but in every household, there are times when the toilet won't flush. It is caused by some common problems, most of which you can quickly check yourself.

First, you need to verify that your home's internal plumbing is working. If water is flowing from the taps, it should also flow into the toilet tank. If the water is not flowing, that's half-good news because it means there's a problem with your utility company. So there's nothing you can do about it other than calling your utility company, but at least your toilet is not broken).

If this isn't the case, there are some common culprits you can look for: a broken toilet flush handle, low water levels in the tank, clogged toilet jets, or a blockage. Most (but not all) of these issues are related to your flushing mechanism.

Let's have a look at these problems and how you can fix them:

The Toilet Is Clogged

Many things can cause a clogged toilet: sanitary products, wipes (anything that shouldn't be flushed), and even excess toilet paper. These objects can accumulate and clog up your sewer line.

However, looking for the reasons for clogged toilets doesn't help fix the issue, as you can't usually see what's causing the blockage. The first sign of a clogged toilet is the high water level in the bowl. There may also be a partial blockage, which you can tell if the toilet doesn't flush or flushes but not strongly enough.

How to fix it? Try loosening the blockage with a plunger or a toilet auger. If such tools don't work, pour a bucket of hot water into the bowl. If the blockage is stubborn and nothing seems to work, you may have to call in a professional plumber for clogged toilet issues who has the right tools to deal with the blockage. In the future, you can avoid a clogged toilet by only flushing down waste and toilet paper.

The Toilet Flush Handle or Chain is Faulty

Although many parts of the flushing mechanism can fail, more often than not, it's the toilet flush handle that is faulty. The toilet flush handle is what you press to flush the toilet; it's essentially a lever that attaches to the flushing mechanism inside the tank.

The toilet flush handle is connected to the flapper by a chain. This chain may have become detached from the flushing mechanism. The chain may also be too long so that it doesn't do its job of pulling up the flapper and flushing the toilet. It is also possible that the chain is too short, the flapper does not close properly, and the toilet runs without filling with water.

How to fix it? Lift up the toilet tank and check that the chain is still attached to the mechanism. If it’s not, clip it back in place. Next, flush and check if the chain is too long or too short. The chain has to be the right length to work correctly.

If the chain looks OK, the problem could be the flapper or the toilet flush handle. Try cleaning the handle to remove any accumulated limescale, and tighten the nut on the back of the handle if you feel it has come loose. If it's completely broken, it needs to be replaced. Both the flapper and handle are easy to replace. Just be sure to take the old parts to the hardware store for reference.

The Toilet Tank Isn't Filling Up

The toilet tank must be able to fill up with water, as it needs to release a great amount of water into the toilet bowl to create a suction effect necessary for the flush. Therefore, if the toilet tank doesn't contain enough water, you'll have a toilet not flushing properly or one with a weaker flush.

How to fix it? Check that there is enough water in the tank by lifting the lid. The water level should be slightly below the overflow tube. If it's lower than this, you need to locate the toilet inlet valve and check that it isn't touching the sides of the tank or isn't incorrectly placed. See if you can put it back to its position and flush again. It can also happen that you don't hear the water running: it's a sign that the flushing mechanism is faulty and needs to be replaced.

The Toilet Jets are Clogged

Toilet jets are small holes under the rim of the toilet bowl. When you flush the toilet, water flows through these tiny holes in a swirling movement. Over time, they can become clogged with limescale, not allowing your toilet to flush correctly.

How to fix it? Toilet jets are easy to clean with a toothbrush, a small nail, or wire. You can also use vinegar or bleach to help remove the blockage faster. Check if the holes are still dirty or clogged by placing a small mirror under the rim. Be sure to clean all jets, and test if this fix worked by flushing the toilet.

Toilet Still Won't Flush? Call a Professional Plumber!

While there are a few simple ways to check why your toilet isn't flushing properly, most repair tasks are not hassle-free, and if you're new to plumbing, they can be overwhelming. You can, of course, replace some parts of the flushing mechanism yourself, loosen any blockages if you have the right tools, and clean parts to remove limescale and corrosion, but often the issue is more complicated than that. In most cases, the easiest way to fix a toilet that's not flushing is to have it done by a professional plumber.

After recent rains, the lighting in our back yard stopped working. The GFCI would not reset. Omar did a great job. He gathered all the information he could and discussed the procedure he would use to trouble shoot and fix the issue and we discussed options and recommendations. He then followed the plan we agreed upon. He also recommended a whole house surge suppressor to bring the main panel up to current code. He did not use a high pressure sell on the suppressor and was fine with not installing one. We did decide to go ahead and get one installed. He was knowledgeable and friendly and was willing to discuss and explain what ever we asked about.

I have had both HVAC and Electricians to our home to give estimates. All were professional with great communication skills and knowledge.

Dan came to fix our heating filament and install an iWave. Like everyone I have interacted with he was informative and easy to work with.
I am Very satisfied with the responsiveness and prefissionalism.

I can't say enough good things about Conejo Services. We called them to get a second opinion on a major plumbing issue. Jimmy came out and put a camera though the various lines involved and gave us his opinion, taking the time to explain the issues and the pros and cons of the options we had. He was professional, courteous, and a straight shooter. It's so hard to know what questions to ask when you are trying to care for your home, and Jimmy really made me feel like he wanted to help us make the best choice. While the repair was not cheap, I feel that it was fairly priced. At the end of the day, I am certain he saved us money and a great deal of stress: he put my mind at ease. And when you are trying to make the best decision about your biggest asset, that is truly priceless. After we came up with a game plan, he gave us a detailed quote that clearly stated the scope of work and didn't blink at guaranteeing it for 25 YEARS. Christa at the office called and scheduled our work and was super friendly. The crew was beyond courteous and conscientious and worked their butts off. The actual plumbing work was top notch. In addition, they had to dig up a portion of the yard where there were plants, and they did a very careful job of making sure the plants weren't harmed and put them back perfectly. We are so happy with the whole experience and highly recommend them. Will use them again in a heartbeat!

Great technicians! Though IMO overpriced. I joined the Platinum Level Preferred Maintenance Club, to save on dispatching on routine items and get great deals on maintenance routines on HVAC, tankless water heater, water and plumbing. Needed a 30 year old wall shower faucet replaced when I signed up, the job was well done, but the cost was exoberant, imo, and I did not recieve a discount on the repair as I missed the fine print and was not told that when I signed, I needed to be a club member for a consectutive 5 months to obtain those repair discounts. I did ask at least twice to get a call to manager, was told the message was forwarded to the office, no response. Now 5 months later had a Heater Maintenance and Dryer Vent cleaning, Eric was the specialist. Excellent service by Eric. However, I received an invoice that day for $200 for the vent cleaning even though that service is listed as part of the PMC at Platinum level. I called CSHPE customer service and was told they would handle it and to ignore the invoice. Three days later, I got the same invoice, again I called, same advice. Got another invoice yesterday. I have not received one today, but it is still early AM. 🤨 Bottom line, good technical work but undermined by pricing perception, membership benefit confusion/misapplication, and unresolved billing/communication problems.

George was awesome! He called and let us know he could come sooner but, made sure that was okay with our schedule. He went above and beyond explaining the issue and made sure all was okay to make sure that issue did occur again. He asked if we were okay with the explanation and if we had any other questions or issues to reach out. Excellent service!

Owen was my electric tech,
and from the conversation over a couple of electrical issues here, I understood quickly that Owen knows the line of work very well: educated, smart, polite, with down the the earth professional demineur... He checked the wiring, and explained the possibilities why my appliance keeps tripping the breaker..
Thank you Owen.
The company has a right set up. They would also remind you about the appointment, and would convinietly call you a few minutes ahead.

They have the right codes... they won't walk in their shoes on your floors either...
I strongly recommend the Conejo company for your electrical issues...

When our 31 year-old furnace suddenly stopped working, they were out within 24 hours of my call. It was a quick and easy replacement part, but something we wouldn’t dare do ourselves. It’s good to know we’ve found a reliable repair service!

He also gave us some options to look at in the future. We signed up for their maintenance plan and feel very confident that Conejo Services will meet our needs now and in the future. Thank you for giving us peace of mind!

This company really stands behind its work. I have the platinum maintenance for my both HVAC and plumbing, both installed by them and it really pays off. The plumbing area, especially, led by Andrew Dilger and team are honest, thorough, skilled and offer options from minimal to full overhaul with pro’s and cons and short vs. long-term financial differentials of each approach. I have an older home with pipes at end of their 60 year shelf-life and it’s a new area for me. It’s really great to be able to trust a company when the product isn’t visible, but buried in the ground. I liked Derek who identified a potential issue during normal maintenance and the oversight of Andrew confirming it and best approach. I think it’s the honest approach set by senior management, including Andrew, Ralph and others. And highly professional! Kudos!

We were on Conejo’s maintenance plan for a while. We found they were very thorough in checking our A/C, plumbing and electric systems. It is worth considering these plans.

We had other work done where we felt the pricing was quite high, like for a garbage disposal and for installing a tankless hot water heater. So consumers should be sure to do price comparisons.

When they put in our tankless hot water heater, there were a couple of code violations that needed to be corrected, plus we had some questions about the costs. But when our concerns finally reached the Customer Service managers, their response was excellent and all our concerns were immediately and satisfactorily resolved.

I strongly suggest getting cost estimates from other companies before hiring Conejo. I was provided an estimate of $7149 to perform what turned out to be 7 hours of work by two (relatively low paid) employees and a couple hours to use specialty equipment to pinpoint failure point. I had a blockage in my home sewer system caused by root intrusion. By using their tool inserted into the sewer pipe they said the blockage was 8 feet deep and under my concrete entryway walkway and would therefore take two workmen 2 to 3 days to complete the repairs. I questioned that pricing since it seemed too high and was provided a reduction of $850 to $6299. That still seemed like a high price but I needed to get the work done quickly so I accepted the bid. (My big mistake.) I monitored the work when their two workmen came to make the repairs. I am retired from SoCalGas so have some knowledge about excavating and fixing damaged pipe. The sewer pipe was only 3 feet deep, not 8 feet deep. The work involved digging and exposing the 4-inch plastic sewer pipe and then cutting out a 3-foot section and installing new pipe, then backfilling the excavation (which was done poorly – was not well compacted – I did this after they left as best I could. I hope my entryway sidewalk doesn’t fail/crack in the future.) They completed the work in 7 hours. I then contacted Conejo and asked to them to reconsider the price since the basis of the estimate was incorrect. I eventually spoke with their plumbing manager, Nick, who said he would speak with the person who developed the estimate and get back to me. Nick never got back to me even though I called their offices twice and texted Nick. The next contact I had from Conejo was a revised bill reducing the charge by $500, leaving me with a bill of $5799. On the positive side, the people I spoke with in their billing and/or scheduling department with friendly and responsive.
