Depending on the sink you have, you’ll find a variety of pipes underneath it. You have lines that bring water to your faucets and a trap, which could be an S-trap or a P-trap depending on where you live. It costs between $150 and $250 to replace just the P-trap. This U-shaped pipe keeps smells from coming back into your home by holding a small amount of water in the bottom of the U. If you smell something terrible, it’s probably time to replace the P-trap under your sink. 

In general, you’ll need to replace your kitchen sink drain pipes when they leak, smell, or are too old. On average, replacing all of the plumbing under your kitchen sink will cost between $100 and $350. Costs will be higher, though, if you add disposal or need a special drain.

Why You Should Replace 

A drain can wear out over time. The stopper that keeps water from leaking out of the sink can start leaking, or the gutter’s surface can rust or become tarnished. It could get a crack or lousy seal, letting water drip from under the sink.

How to Choose a New Drain 

When looking for a replacement, there are a few things to consider. Each drain comprises a group of parts that must match the design of the sink and the way the drain pipe under the sink is connected. 

Single Basin. For single basin designs, the drain must fit the hole in the bottom of the sink and seal well. You must ensure you know how much space you need around the trap and what size and style of connection you need to fit the drain pipe below. 

Multi-Basin. Most sinks with two basins have a single trap and a drain that goes to both. However, each drain can have its catch. Pick a replacement that fits the sink well and has a surprise that makes it easy to connect to the pipe below.
