Question: My toilet is constantly running. What should I do?
Answer: It is crucial to find out why your toilet is running to avoid wasting water and receiving high taxes. Several parts can cause the water to run continuously. They include a flapper that is not well connected, a damaged fill valve, or a water level in the tank exceeding the recommended level. Correcting any of these issues is simple, and you can do it yourself. Replace the worn-out parts and adjust the flapper to the right level.

If you’re not confident about doing the repairs, then you should hire a professional plumber.

Question: The base of my toilet is leaking. Can I fix it, or do I need to call a plumber?
Answer: When you notice that the base of your toilet is leaking, you should have it repaired immediately. But first of all, you should cease using the toilet as you may aggravate the issue. In most cases, the wax ring at the base of the toilet may be having a problem.

Since this is a delicate matter, you should not attempt to fix it but contact a professional plumber to fix it for you. The plumber may have to remove the entire toilet before concluding the next step to take.
