Kitchen sink
won't drain?

Kitchen drains take a lot of abuse from grease, food particles, and soap, which is a recipe for buildup that cabling alone cannot fix for good. We cable the line for immediate relief. For drains that keep clogging, we offer hydrojetting, which scours the pipe walls clean so clogs stay away longer.

Why kitchen drains clog more

Why grease keeps coming back.

Grease cools and solidifies inside drainpipes, building up layer by layer over years. By the time you notice slow drainage, the inside diameter of your pipe may be reduced by 50% or more.

Cabling punches a hole through the grease and restores flow temporarily. Within months (sometimes weeks), the buildup re-closes the hole. Hydrojetting scrubs the grease off the pipe walls, restoring the full diameter, so the line stays clear far longer.

If your kitchen drain keeps clogging after it's been cabled, ask us about hydrojetting.

Keep it flowing

What not to put down the kitchen drain.

  • Grease, oil and fat. Let it cool, wipe it out of the pan with a paper towel, and throw the towel in the trash.
  • Coffee grounds and eggshells. They settle in the pipe and bind with grease.
  • Rice and pasta. They swell with water.
  • Stringy peels and stalks like celery and onion skins. Potato peels too: they turn into a starchy paste.

Kitchen line or main line? If only the kitchen sink is slow, the clog is usually in the kitchen line. If other drains act up too, such as a toilet or tub gurgling when the dishwasher runs, the main sewer line is likely blocked.

When we come out, we clear the line with a cable or a hydrojet, depending on what we find, and on a main line we run a camera every time. You get your options in writing, each with one flat-rate price, before any work begins. More about drain cleaning and hydrojetting →
