How do you remove grease from the sewer lines in a home?

Answer 1

First of all,,,and no real offense, you need to stop pouring the residue from fried pork chops down the kitchen,,,or any other drain.
To remove it may take lots of Liquid Plumber///Degreasers/// Petroleum based solvents, along with boiling water.

Any drain line in a home is designed for the expulsion of water, some food particles, waste in a bathroom, but not for grease from cooking, paint cleanups, changing the coolant in the car, etc etc etc.

I won't even tell you what things are found in "Lift Station" residue tanks.

What happens is very similar to Plaque, building up in a Human artery. The grease finds voids, or projections to stick to. It "collects" other debris that goes into drains,,,especially when it cools, and in the process, hardens, or becomes a debris trap, eventually clogging a drain line.

Certainly included in your efforts, might be a plumbing "Snake" or a professional,,, who might at some point, after paying them $40 plus dollars,,,advise you as I just have.

Hot water would be a problem because you'd have to heat up the entire sewer drain line for its entire length trying to melt the grease - it would take more hot water than is in your water heater and would take, like, 24 hours to get hot enough. Lye or Drano also is unlikely to remain concentrated enough for the entire length of sewer line to soften the deposits.

You best bet is a mechanical means of removal - go rent a electric powered rotary sewer line cleaner and run it down the lines. It also will attack tree root infiltration into the sewer line, which is more common than grease problems - you may actually have a tree root problem rather than grease; it is hard to tell the difference.

There is one more technique but use it sparingly. You can take a garden hose and seal it against the sink drain. This will clear a single plugged drain line of grease within the house (it only will work until it connects with another branch or vent on the sewer line). The limitation is that it applies pressure to the drain line to clear the plug - if you overpressure the line you can get a leak or burst and have a real mess on your hands - the right tool for the job is a mechanical snake.
