Reasons Your Toilet Keeps Running and How to Repair It

09/01/2025 | Hawkrown

Toilets are commonly used sanitary ware in households, but improper use can lead to malfunctions. If your toilet won’t hold water and keeps running, how can you fix it? What should you pay attention to in daily use? Let’s take a look!

How to Fix a Toilet That Won’t Hold Water and Keeps Running:

1、Turn off the water supply valve and drain the water from the tank. Then, add colored ink into the tank. If colored water flows out, it indicates a crack inside the toilet, and you will need to replace it.

2、It may be that the connection between the lower part of the toilet tank and the water line is loose, resulting in a leak. It is recommended to re-adhere the connection.

3、Regularly check the toilet float. Its condition will determine the water level in the tank, which can cause the toilet to keep running.

Daily Use Tips for Toilets:

1、Avoid throwing hard objects into the toilet and definitely do not dispose of leftover food, as this can lead to blockages.

2、Maintain toilet cleanliness by wiping it down with a soft cloth daily to prevent dirt accumulation.

3、If your home has hard water with many impurities, be sure to regularly clear the toilet's outlet holes.

How to Choose a Toilet:

1、Toilet Glaze

When selecting a toilet, check its glaze. A good toilet has a smooth and even glaze with no bubbles or granules. It should have strong self-cleaning capabilities, not easily discoloring over years of use. Additionally, a high-quality toilet uses a full glaze process, ensuring smooth drainage without clogs.

2、Toilet Hardware Accessories

Pay attention to the components inside the tank, which are often not visible externally. Test them by pressing the flush button; if it feels light and unresponsive, it indicates poor elasticity and may struggle with flushing. In contrast, a good component feels sturdy, is highly elastic, and has strong flushing power.

3、Toilet Style

Lastly, consider the style of the toilet. There are integrated and split types mainly differing in the design of the water tank. An integrated toilet isn't necessarily superior to a split one; the former usually has a lower production rate and higher manufacturing cost, leading to higher profits for retailers, which is why they may be promoted more heavily.
