We use toilets every day, but there can be many issues when flushing. What should we do if the toilet doesn't refill after flushing?
What to do if the toilet doesn't refill after flushing？
It might be due to low water pressure in your home, which can cause a weak flow of water and slow the refill of the toilet. You can consider installing a booster pump. It may also be that the filter screen hasn’t been cleaned for a long time, causing the inlet valve to be blocked and affecting the refill speed. In this case, clean the filter screen and reinstall it. Additionally, aging or malfunctioning components may slow down the refill; generally, replacing old or damaged parts can resolve this issue.
What are the methods for unblocking a toilet？
If the toilet is clogged, appropriate methods should be used to clear the blockage. Here are some commonly used methods:
1、Fill the tank with water and then discharge it into the toilet bowl forcefully several times. The pressure may help to clear the blockage. If this doesn’t work, try inserting a stick into the toilet's drain hole to dislodge the clog.
2、You can also use tape to create pressure. Prepare a roll of tape, typically around 30 centimeters wide, and dry the surrounding area of the toilet with a cloth. Then, apply the tape around the toilet, ensuring the edges are flat. As the tape encounters pressure, it will bulge; pressing down on the tape may help to unblock the toilet.
3、Consider purchasing a plumbing snake or spring auger from a store; these tools are easy to use and reasonably priced.
4、If the above methods fail, it's best to contact a professional plumber to handle the situation.
In summary：the above are solutions for when a toilet doesn’t refill after flushing. As discussed, there are various reasons for this issue. It’s important to identify the cause and choose the appropriate method for resolution to prevent damage to the toilet and avoid similar problems in the future. We hope this information is helpful to everyone.
