Most Common Plumbing Problems With Toilets


Toilets are an essential part of any household bathroom, but even with reasonable care, they can run into clogs and malfunctions. A high-pressure plunger is an effective way to push out blockages, but it’s very time-consuming. Professional plumbing services will probably have better options.

Toilet Installation Regular Price

Plumbing services can vary in price depending on the amount of work required, the plumbing company you call, and the tools needed. For example, if it’s basic services, you can generally expect to pay a toilet installation price of around $150. However, if the bathroom plumbing needs to be repaired first, you could face additional costs of $350 – $800 on top of the basic services fee.

The Most Common Plumbing Problems in a Toilet You Can Face

Below are some of the most common plumbing problems in the washroom and if you are unfamiliar with some of the terms you can consult this plumbing glossary to learn more.

Running Toilet

A running toilet can cost you hundreds of dollars a month in water usage or other damages. A common issue among many households is that a running toilet can be an annoyance and can also be an incredible waste of water. While it might seem like a minor problem, this toilet leak can lead to incredibly high water bills if not fixed as soon as possible.

What Causes Running Toilets?

Running toilet can be a result of the following factors;

  • Flush Valve/ Flapper Seal. A flush valve is a three-part system that you can compare to an old-fashioned toilet. The flapper seal can become warped and worn. That prevents a good seal which can cause the tank water to leak into the bowl and out of the toilet.
  • Flapper Chain. It may have been too short or too long for your toilet handle when you originally installed the toilet. That prevents the flapper seal from closing correctly, and water will continually run.
  • Fill Valve. Your toilet’s fill valve may be leaking, which is causing it to run continuously.

How Can Running Toilets Be Diagnosed?

To check if your toilet’s flapper seal or flush valve needs replacing, add a few drops of food coloring to the tank and wait a few minutes. If the coloured water in the tank appears in the bowl without flushing, it indicates an issue with the seal or the valve that needs fixing.

How to Fix Running Toilet

If you are experiencing a running toilet problem, don’t wait to incur more costs. First, you need to contact a plumber near you so that they can analyze the situation. Then, they will replace the damaged areas.

Clogged Drains

Any pipe in your home can become clogged at any given time. That will significantly impair your drainage system. Therefore, it is essential to understand what causes it so you can avoid the problem.

What Causes Clogged Drains?

Clogged drains can be the result of;

  • Flushing the wrong waste apart from the regular human waste and tissue paper. Diapers, cotton balls, swabs, and tissues cannot break down when flushing.
  • The trap is clogged. Below every sink is a drainpipe, and it has a little trap that collects water. The water acts as an essential barrier to bad smells coming out of the sewer line. The trap in your toilet is excellent at this job, but don’t forget that this bend in the pipe also makes a good place for a clog to form.
  • Inefficient Flapper. The rubber gasket at the bottom of your toilet tank is called a flapper. When the water in the toilet tank reaches a certain height, the flapper pops open to allow it to flow down into the drainpipe. If the flapper doesn’t open fully, you may not get a strong enough flush, which can clog up your pipes by failing to push everything from the bowl down the drain. 

How to Diagnose Clogged Drains

  • Watch out for poor flushing. The water doesn’t flush properly. It will stay in the bowl for long hours or flow over the top of the bowl.
  • Watch for gurgling sounds up in your bathtub or shower drains whenever you flush the toilet.

How to Fix Clogged Drains

Once you notice any sign that shows the possibility of having a clogged drain, you should seek professional help from plumbers in Toronto. The plumber can use special devices like the plumbing snake to fix your blocked drains.


Experiencing backups can be nasty. Instead of waste material flowing through to the sewer, it all comes back up to your toilet.

What Causes Backups?

Backups are the result of the following factors;

  • Clogging resulting from foreign materials. If you or your family flush other materials apart from human waste and tissue paper, that can cause blockage and backups. Using too much toilet paper can also result in the same.
  • Toys. Toys are not easy to flush in the toilet. That’s because they are not flushable. They obstruct pipes and clog toilets.
  • Plumbing Vents. If you’ve plunged your toilet and you have not managed to resolve the problem, check for a blocked plumbing vent. Debris, leaves, or sticks could be blocking the venting and creating a low-flow toilet effect. Your plumbing system will have less pressure without proper venting, and waste and paper will not pass through plumbing pipes. 

How to Diagnose Backups

Run the bathroom sink for some time as you pay attention to the toilet. You may hear some gurgling sounds and water bubbling too from the washroom. They are an indicator that the main sewer line could be having some issues.

How to Fix Backups

If you have backup trouble in your toilet, you should contact a professional plumber to check your whole toilet plumbing system.
