You use your toilet system daily and its primary function is to take human waste and dispose of it in a sanitary manner. Because of the constant use, you can experience some common problems with your toilet. Blockages, leaks from the base of the toilet, cracked cisterns and a constantly running flush mechanism are some of the typical situations that a homeowner will experience with their toilet system.

How Do Toilets Operate?

Your toilet system works by taking waste and water in one bowl. When flushed, the mechanism sucks the water and waste down a pipe that is connected to your sewerage drain. Your toilet is made up of different parts and components. Let's start with the tank:

  • Blush button/handle
  • Toilet Flapper
  • Float Ball
  • Valve
  • Overflow tube
  • Refill Tube

How Toilet Cisterns Work

The flush handle is connected to an arm that has a chain and is attached to the toilet flapper. The flapper covers a hole that allows water to enter and drain the bowl. There is a float ball that is connected to the valve.

To flush the toilet mechanism you pull on the handle or chain. This will pull on the flapper which then opens up the hole allowing water to drain into the bowl. When the water level gets low, the toilet flapper will close due to the water supply being lower and not triggering the flapper

The float ball sits on top of the water, so when you flush the toilet and the water level begins to drop, the ball that is connected to both the valve and flapper chain will open up. Water from the water supply will then begin to refill the tank. This is because the valve is open and filling the tank again.

Why Does My Toilet Keep Running?

When you flush your toilet but the water keeps running it can be frustrating to hear a constant trickle of water. If you think of a running toilet as an internal leak, then you will have to inspect the parts inside of the tank and examine their condition. There are a few common causes if your toilet keeps running:

  • Cracked or faulty toilet flapper
  • Toilet Flapper chain is too long or short
  • Float ball too big or small
  • Flush button or lever is stuck or loose

5 Tips To Stop A Toilet From Running

If you wish to investigate the issue with a running toilet, there are some tools you will need. These tools can be purchased at your local hardware store:

  • Cutting Pliers
  • Flathead and Phillips screwdriver
  • Pliers
  • Replacement fill valve
  • Replacement of toilet flapper

If you are confident to carry out basic toilet repairs yourself, there are some simple step by step instructions we have listed below that can help you fix your leaking toilet.

Toilet Won't Stop Running

Turn off the water supply

Before you begin, you need to stop the water supply before commencing work on the toilet. You can find the shutoff valve below the toilet bowl. To carry out any work on a toilet, stopping water from entering and leaving the toilet tank is crucial to access the different parts such as flush valves and flat balls.

Inspect the fill valve

Remove the lid to the toilet tank. By removing the lid you will be able to better inspect the different parts associated with the cistern. Thoroughly clean the fill valve with warm water and soap. Reattach the lid and turn the water back on to ensure there are no leaks.

Inspect the float arm and lift rod

The float arm should be straight and attached to the fill valve as well as the actual ball. If the ball is loose or not in line with the arm, you may need to replace it. The lift rod needs to allow the flapper to position itself into the opening correctly. You can adjust the rod or purchase a new flapper to create a good seal.

Check the level of water in the tank

It is best to keep the toilet tank water level at 2.5 cm to 5 cm below the overflow tube. If you need to adjust the height of the water inside the cistern, you can find a screw-on top of the float. Turning the screw left will lower the float and reduce the height of water into the bowl.

Inspect the toilet flapper

Make sure you stop any water flow before you carry out this next step. The flapper must create an airtight seal on the opening or it will cause water to keep running. Cleaning the flapper will indicate whether it is working properly. Remove the old flapper and replace it with a new one. You can find a replacement by going to most home improvement stores and purchasing a new one.

When To Call A Professional

If after trying these methods your toilet is still running, it might be a good idea to call a plumber. An experienced plumbing team is able to repair the issues with your toilet such as blockages and leaks as well as broken flush buttons. It is best to call a plumber who is fully licenced and has the experience to fix running toilets, replacement of parts, unblocking the toilet, and knows how a toilet system works.

Getting Expert Plumbing Help

When you flush the toilet, you expect it to stop running after a few seconds. If the bowl keeps running, there could be other problems that need to be taken care of quickly. This may cause issues for other parts of your plumbing system if not fixed. Along with this, think of the water that is wasted and a spike in your water bill.

There are many plumbing companies out there, but you need to find the right team to solve the problem correctly the first time. You need a team that knows how to solve your plumbing problems correctly and stop a running toilet permanently. Solve your plumbing issues the right way and have a stress free home once again.
