What Does Toilet P Trap Do?

An element of a piped drain system known as a P-trap employs a curved trap to catch water and keep sewer gases out of the house. It is typically located under the sink in the kitchen or bathroom or inside the base of the toilet bowl.

A toilet P-trap comprises two primary components: the curve and the cleanout. The curve holds water in the trap and prevents sewer gases from entering the drain. The cleanout is a small opening at the bottom of the trap that allows you to access it if it becomes clogged.

When Should Replace Old Toilet P Trap With A New One:

If your old P trap toilet is over 20 years old, it’s probably time to replace it with a new one. P trap toilets can last for decades but eventually need to be replaced.

The main reason to replace your P trap toilet is that the seals around the trap can degrade over time and allow water to leak into the bowl. This can potentially cause expensive damage to your bathroom.

While you could replace the seals, it’s usually not worth the hassle, and it’s generally cheaper to get a new P-trap toilet.

Another reason to replace your P trap toilet is if you’re redesigning your bathroom and want a new look. However, when to replace your outdated P-trap toilet is ultimately yours.
