How can you fix a leaky toilet overflow pipe

This is how to stop the overflow pipe from dripping down my toilet.

The washer of the float valve may need to be replaced if the toilet overflow pipe continues to leak. To eliminate any possibility of toilet overflow, the first step is to shut off all water supply.

Is a leaking pipe dangerous? If your overflow pipe leaks, it could indicate a problem in the float valve. Most common issues are a leak within the float. This means that it must be replaced or that there is a problem with its washers. These will require refitting. You should contact a licensed plumber if you suspect you have a leak.

This is how the overflow pipe drips.

Leaking overflow pipes indicate that water is entering the cistern where it shouldn't. A faulty ball valve is most commonly responsible. A dripping overflow may not be obvious during normal water usage. However, it could indicate that a faulty valve has dripped into the cistern all night. Verify the ball valve.

What's the purpose of the water pipe that drips outside my house?

Your central air conditioner's condensate drainage line is the most likely source of water leakage from outside pipes. It is normal to see the water leak from just one pipe. This indicates that your drain line is functioning normally and is not blocked.
