Why is My Double Kitchen Sink Backing Up to the Other Side?

If you’ve ever stood at your kitchen sink and noticed water creeping up from one side to the other, you know how frustrating it can be. At Trenchless Sewer Plumbing in Los Angeles, we’ve seen this happen time and time again. While it might look like a small issue at first, double sink backups can signal a more serious underlying plumbing problem. So, what’s causing this, and what can you do about it? Let’s break it down.

Common Causes of Double Sink Backups

When you’re dealing with a double kitchen sink backup, the main culprits are often a blocked main drainpipe or a clogged garbage disposal. If you’ve got food scraps, grease, and other debris building up in your pipes, it’s only a matter of time before water starts to back up from one side of your sink to the other. In fact, kitchen sinks take quite the beating, especially with everything we toss down there—whether it’s food waste or oil residue.

Slow Draining? It’s Time to Pay Attention

Notice water draining slower than usual? That’s a red flag. A slow drain is often a sign of a partial clog, which, if left unchecked, can develop into a full blockage. Over time, these clogs prevent water from flowing freely, and eventually, you’ll have water backing up into both sides of your sink. Fats, oils, and food scraps are notorious for causing this kind of buildup, especially if they’re regularly sent down the drain.

Key Signs Your Double Sink Might Be in Trouble:

  • Water rising in the opposite sink when the garbage disposal runs.
  • Slow draining water in one or both sinks.
  • Gurgling noises from the drain.
  • Standing water that takes a long time to clear.
  • Foul odors coming from the drain, indicating trapped food and grease.

If any of these sound familiar, it might be time to investigate further or give us a call at Trenchless Sewer Plumbing!

What’s Really Happening When Water Backs Up?

In most cases, water is backing up from one side of your double sink to the other because there’s a blockage in the main drain beyond the garbage disposal. When you run the disposal, it acts like a pump, pushing water out. But when you turn it off, gravity takes over, and the water flows back, filling the other side of the sink. This tells us that the clog is deeper in the drain system, possibly in the main line or even further down.

Don’t Let a Small Issue Turn into a Big Problem

At Trenchless Sewer Plumbing, we always tell our customers that catching a problem early can save a lot of time, money, and stress.
