Quick answer: Proper kitchen sink drain cleaning removes the clog and the grease coating the pipe. We check the trap and disposal, then run an auger through the line to the stack. When the pipe wall is heavily coated, we recommend hydro jetting to scour it clean. Then we test the sink, disposal and dishwasher together at full flow.

Kitchen sink drain cleaning removes the grease, food particles and soap residue that collect in the sink trap and the drain line behind the wall. The kitchen is the hardest working drain in most homes. Every rinse carries a little oil, starch and scraps, and over months that material coats the pipe like plaque. One day the sink drains slowly. Soon after, the second bowl fills when the dishwasher runs, or water backs up and smells.

A kitchen clog is rarely just in the trap under the sink. The trap is easy to reach, but the real buildup is usually in the horizontal pipe inside the wall or floor, where grease cools and hardens. In many Philadelphia rowhomes the kitchen sits in a back addition with a long, flat drain run to the stack, which gives grease plenty of room to settle. That is why pouring hot water or a store bought cleaner rarely fixes it for long.

We clear kitchen sink drains with augers sized for the line, and when grease is heavy we recommend hydro jetting to scour the pipe wall clean. We check the disposal and dishwasher connections, since both feed into the same drain, and we test at full flow before we leave. You get an upfront quote first, and we clean up when we are done.

What we clear

Common Kitchen Sink Drain Cleaning Situations

Grease Clogs

Cooking oil, butter and meat fat run down the drain warm and liquid, then cool and stick to the pipe. Layer by layer the opening narrows. Grease is the top cause of kitchen clogs, and it needs real cleaning of the pipe wall, not just a hole punched through it.

Food and Starch Clogs

Rice, pasta, potato peels, eggshells and coffee grounds swell or pack together in the trap and line. A disposal grinds them small but does not make them disappear. Combined with grease, they form a dense paste that stops the sink.

Disposal and Dishwasher Backups

The dishwasher drains through the disposal or a tailpiece connection into the same kitchen line. If that line is restricted, dishwasher water ends up in the sink. We clear the shared drain and check the connection so both appliances drain properly.

Long Horizontal Runs

Kitchens in rowhome back additions and remodeled kitchens often send water through a long, nearly flat pipe before it reaches the stack. Low slope lets grease settle. These lines benefit most from hydro jetting and occasional maintenance cleaning.

How it works

Our Kitchen Sink Drain Cleaning Process

Check the Fixtures

We run the sink, disposal and dishwasher to see how the line behaves. We check the trap and the disposal to rule out a simple local clog. If the clog is further down the line, we find the best access point, whether that is the trap arm, a cleanout or the stack.

Explain and Quote

We tell you where we believe the clog sits and what it is made of, usually grease and food solids. You get an upfront quote for augering or hydro jetting, with the reason for the choice. You approve before anything starts.

Clean the Line

We run an auger through the line to open the clog, then pull back grease and debris. When the pipe wall is heavily coated, hydro jetting cuts and flushes the grease all the way to the stack so the line is clean, not just open.

Reassemble and Test

We reconnect the trap with fresh seals if needed, run the sink, disposal and dishwasher together at full flow, and check for leaks under the cabinet. Then we wipe down the area and give you simple habits to keep the line clear.

Why Kitchen Sink Drains Clog in Philadelphia Rowhomes

In a typical Philadelphia rowhome, the kitchen sits at the back of the first floor, often in a back addition built later than the main house. The sink drain may travel a long way across the floor or ceiling before it ties into the cast iron stack. Those long runs, older galvanized or cast iron pipe and decades of grease mean kitchen lines in South Philly, Fishtown, West Philly and Northeast homes clog more often than people expect. Pipes in back additions can also sit along exterior walls that get cold in January and February, which makes grease harden even faster.

Restaurants and commercial kitchens across Center City, Passyunk and Manayunk face a heavier version of the same problem, and grease traps add another layer to manage. At home, the fix is a clean line and a few good habits. We clear the pipe properly and show you what came out of it.

Pricing

What Affects the Cost of Kitchen Sink Drain Cleaning

Kitchen sink drain cleaning cost depends on how far down the line the clog sits, how much grease has built up and how we access the pipe. A clog in the trap or disposal is simpler than a grease plug deep in a long back addition run. Heavy buildup may call for hydro jetting instead of augering. Tight cabinets, missing cleanouts and after hours service also play a part. You get an upfront quote before any work starts.

Prevention

How to Keep It From Coming Back

  • Pour cooled grease into a can or jar and throw it out instead of rinsing it down the sink.
  • Wipe greasy pans and plates with a paper towel before washing them.
  • Use a sink strainer and empty it into the trash after every use.
  • Run cold water while using the disposal and for a few seconds after.
  • Call at the first sign of slow draining, before grease hardens into a full plug.

FAQ

Kitchen Sink Drain Cleaning Questions, Answered

Proper kitchen sink drain cleaning removes the clog and the grease coating the pipe. We check the trap and disposal, then run an auger through the line to the stack. When the pipe wall is heavily coated, we recommend hydro jetting to scour it clean. Then we test the sink, disposal and dishwasher together at full flow.

The dishwasher drains into the same pipe as the sink, usually through the disposal or a branch tailpiece. When that kitchen line is partly clogged with grease and food, the dishwasher's pumped water has nowhere to go and rises in the sink. Clearing the kitchen drain line usually fixes it. We also check the dishwasher drain connection.

Hot tap water helps keep grease moving, but boiling water is a poor fix for a real clog. It can soften grease that then hardens further down the line, and it can damage PVC trap fittings and porcelain sinks. If the sink is still slow after a plunger, the clog needs mechanical cleaning.

A disposal does not cause clogs by itself, but it makes it easy to send too much food down the line. Starchy foods, eggshells, fibrous peels and coffee grounds pack together with grease. Run plenty of cold water while grinding, feed food slowly, and keep grease out entirely to keep the line clear.

Yes. Back addition kitchens are among the most common kitchen calls we get in Philadelphia. These drains often run long and fairly flat through old cast iron or galvanized pipe to the stack. We choose the access point that reaches the clog, often through the trap arm or a cleanout, and jet the line if grease is heavy.

Most homes only need it when the sink slows down. Homes that cook a lot, have long kitchen runs or older pipe may benefit from cleaning every year or two before a full clog. If your kitchen sink has clogged more than once in a year, a hydro jetting cleaning is usually worth it.

Keep out cooking grease and oil, meat fat, coffee grounds, eggshells, rice, pasta, bread, flour, potato peels, celery and other fibrous scraps. Paint, plaster and caulk do not belong there either. Wipe greasy pans with a paper towel before washing and put scraps in the trash or compost.
