That tiny hole next to the tap on your bathroom sink might not seem important, but it’s actually a careful design choice. It’s about a third of the way up the pond, linked to the sewage pipe, and very important for keeping disasters from happening.
People can forget to turn off the tap when they are not paying attention, which can cause the water level to rise. This clever hole saves the day, though! When the water level in the bowl hits two-thirds of the way up, it runs into the pipe to stop it from overflowing and spilling.
But this hole can also hold unwanted things, which can help bacteria and mould grow. This could lead to unpleasant smells that make the bathroom less clean.
A simple do-it-yourself fix for this is to mix vinegar and baking soda in equal parts. You can pour it into the overflow hole and wait 5 to 10 minutes for it to do its job. Use warm water to flush to clean.
This preventive method makes the bathroom cleaner. When you see that little hole again, think about what it does for water management and planning.
