Video compilation of clogged sewers being unblocked and water begins to drain

Hello everyone! Welcome to the Plumber Story Channel.

This is a video of moment the sewer is cleaned and the water is drained.
It is my favorite moment to get rid of the blockage.
Most of the this video happens in the sink pipeline.
Korean sink pipelines don't meet toilet pipes. They never ever meet.
This may be the difference from the plumbing in your country.
In Korea, most of the sink lines are clogged with oil.

We have a different system of piping from the foreign country.
There are two sewer lines in the last manhole.
The two lines never meet.
They NEVER meet.

Line 1 is the toilet sewer line. It is blocked with poop, tissue, wet wipes, etc.
Line 2 is the sink sewer line.(Sink, bathtub, wash basin, laundry room, etc.) - It’s blocked by hair, oil, fat, and grease.

Korean buildings should be divided into two sewer lines.
The building law is fixed.
Korean buildings must be built according to the law.

The oil video is Line 2.
That's in the background.

The following are the commonalities and problems of the houses in the oil video.
Just for oil, fat, and grease.

Problem 1:
Many houses use Line 2.
All the houses in the video are multi-family homes.
That's probably the biggest difference from foreign country.
The communal piping is poorly managed.

Problem 2:
There's too many curves.
Too many 90 degree elbow pipes. (?)

Problem 3:
The pipes are long.

Problem 4:
The pipe size is too small for many houses.

The buildings that a plumber built thoughtlessly have problems like this.
Well-designed houses do not get clogged.

You think the pipes are clogged with too much oil.
You think Koreans eat too much oil.
You think Koreans throw too much oil into the drain.

No. It’s simply because there are too many houses using Line 2.

This is the problem with Korean pipes.
But people who design or build buildings don't want to change their ways.
It seems I‘ll be keeping my job for quite a long time.
In the future, you will continue to see oil on my channel.

Thank you.

The drainage system different in Korea vs US. Seems like some areas have poor drainage which causes a lot of standstill in drainage, which in turn allows grease to just sit and stick to things. These kinds of blockages takes years to accumulate, but once its blocked, it's REALLY blocked. Even if you only use little fats in foods, a poor drainage system will collect all of it like its on sale.

it is not coming out of people, but out of peoples kitchen. This is a kitchen drainage, not toilet. Toilet drainage is separate. If the slope is not high enough, the water flows slowly giving more chances for the oil to stick to the walls of the pipe and build up over time.
