A leaking toilet can be incredibly frustrating, not to mention wasteful. With every drop that escapes the tank, you’re literally watching money go down the drain in the form of higher water bills. Fortunately, many toilet leaks are relatively easy to fix yourself. 

In this guide, we’ll explore some common do-it-yourself solutions for repairing a leaky toilet tank. We’ll also discuss when it’s best to call in a professional plumber to handle the job. Whether it’s a constant trickle or a puddle on the floor, you’ll learn how to stop toilet leaks and prevent wasted water.

Get to Know the Basics of a Toilet Cistern

Before we jump into the troubleshooting steps, let’s take a moment to understand the inner workings of a toilet cistern. Trust us, these details matter.

When you flush a toilet, a chain or link arm lifts a device called a ‘flapper,’ allowing water to flow into the bowl. As the water drains, a float drops and signals a valve to refill the tank. The water continuously leaks into the bowl if the flapper gets stuck open. 

Other issues can also arise with the cistern washer, water valve, float valve, drainage system, or flush pipe seal.

DIY Solutions for a Leaking Toilet Cistern

1. Check the Flapper

A faulty flapper is one of the most common causes of a leaking toilet cistern. To fix this, start by inspecting the flapper for any obstructions or misalignments. 

Adjust it slightly to ensure it settles back in place after being lifted during a flush. If the flapper is worn, old, or covered in sediment, consider cleaning or replacing it. 

Additionally, check the rubber seal and replace it if necessary. If you can’t fix it yourself, have an expert toilet plumber attend to it for you.

2. Examine the Water Valve

Ensure the tank’s water level is up to the water line. If it’s below the line, the float may need adjustment. Ensure the water valve is fully turned on to fill the tank properly.

3. Test the Float Valve

If adjusting the float valve doesn’t solve the issue, test it to ensure it shuts off properly. Pull up on the float, and if the running stops, you may need to adjust the float level or replace the washers in the inlet valve. 

Excessive water pressure can also lead to overflow problems, so consider adjusting the valve accordingly.

4. Check the Drainage System

If you suspect the leak is coming from between the toilet and the floor, it’s likely a problem with the drainage system. Fixing this issue requires removing the toilet, which is best left to a professional plumber. Contact our local experts to handle this task safely and effectively.

5. Inspect the Flush Pipe Seal

If the leak appears to be coming from higher up, the flush pipe seal may be damaged. This seal is located between the tank and the bowl and can wear out over time. Replacing the flush pipe seal is a more complex job, so seeking professional assistance is recommended.
