Sewage and drain systems are part of modern history and essential part to understand the process of development
of construction of water systems in human history process.
In ancient world, most of the sophisticated Sewage and Drain and water systems, where built in and for the kings
and the rich people. It was until, everyone in the society understood that it was a common problem.
One of the most ancient sewage system and drainage are traced back to the Ancient Indus. These systems have
amazing similarities to our modern sewage systems. Almost all houses in cities such Harappa and Mohenjo-Daro in
India and Pakistan had an access to fresh water and drain systems facilities. Waste waters systems were designed to
direct to a covered Drain systems which ended in major streets.
Fast growth of cities in the middle and in the last 200 years, created the need to design and implement the same
basic Sewer and drain principals, but this time, it was for much bigger population, for millions of people in each
Type of Drains
Define as the drain system that will carry out the waste water from the building (Residential or Commercial) to
the city sewage system. The law in USA, in the vast majority of the counties and cities, requires the Home Owner or
the Property Owner (Commercial) to maintain the Mainline and repair it!!
(Note: the home owner is responsible for the sewer line all the way even the connection to the city, which is
called the "Saddle" or "The City Tie In". Sewer mains can be from 6 feet deep to 10 feet deep due to freeze line
specifications for the area)
Drain systems that are located inside buildings walls (Housed, condo complexes, and commercial buildings) and
will carry waste water into the Street main line.
All of your drains in your house is considered secondary lines for example: kitchen, laundry, tub/shower and
hand sink drains are all considered secondary drains. They all consist from 1 inch pipe that will end up in a 3
inch or 4 inch main line. The toilet secondary line, is the only one in the house that its size on goes from 3 to 4
We can find only the mainline will exit the house and go to the street. If you have an alley almost all the time
the main Drain will exit there to the city drain.
Residential drain problems can be categorized into Kitchen, Bath Tub, Shower, Laundry and Toilet. All these
lines are considered secondary and will connect to the main line.
Bathtubs and Shower drain Problems-
No surprise here, hair is the main cause for slow or complete stoppage. Soap, other dirt, shampoo, and hair
products create the problem. In most cases if the problem persists and is not treated properly, the pipes will
eventually collapse and will cause a major problem.
To unclog the drain, Plumbers will use a 3/8 inch cable to clear the drain. And depending how dirty the drain
is, and how hard and solid the build-up in the pipe is, we might need to run a Hydro-Jetter to clear the Drain
completely. A snake will push and "Drill" a hole in the clogged drain, while a Hydro-Jetter will break and clear
the crystallized solids accumulated on the pipe! Recommendation will be, using Hydro-Jett every 5 years in showers
Kitchen Drain clogs are caused by food debris, grease and years of buildup, rice and pasta leftover should not
be used in a garbage disposal. A secondary snake machine with ï¿½inch cable will clear the drain.
Hydro-Jetting is almost always recommended to actually clean the drain and will have the drain running up to 10
years depending what goes down the drain. Most Plumbers will warrantee if Hydro-Jetting is used.
A typical Clog is due also for hair, line, dirt soap parts that will slow the flow and eventually stops up the
drain. A Secondary snake machine with ï¿½inch cable is used to clear the drain, but plumber will give warranty only
for a month or two. A Hydro-Jetter is almost recommended to actually clean the drain and open its original size. In
most cases, it is recommended that this secondary lines every 10-15 years to prevent a major drain problem that can
end in broken pipes.
These clogs are due to the fact, that when many products that are washed down like toothpaste, mouth wash and
soap, hand washed dirt etc. When combining all those chemicals over the time the drain just built up and stops the
drain. A snake 3/8 inch cable clears the drain. Depending how dirty the drain is, a Hydro-Jetter to actually
cleaning the drain.
These drains get all kind of dirt, dust, leafs and debris (all kinds), and will clog these drains. A secondary
snake ï¿½inch cable is used to unclog the drain.
Toilet / Maintenance -
A toilet clogged sometimes is just inside the toilet and can be cleared with a hand Auger Cable. After clearing
the toilet, it is important to check the water flow in the basement (if there is one) in order to make sure that
the main line is clear too!
The main line drain is the heart of the property (Residential, Commercial) sewage system. A stoppage in the main
sewer main line can cause immediately a flood in the basement (If existed) or flooding other parts of the house,
causing damaged to carpets and other valuable items in the house. Main line should be snaked immediately
with cable. A Skilled plumber can make that determination on where the clog is at. Sewer main stoppage is
usually due to roots, baby wipes, partially collapsed pipes, or complete off-set.
A sewer camera should always be run to inspect these drains. In most cases snaking and hydro-jetting the main
line will solve the problem unless pipe structure problem is detected. In case of of-set or broken pipe or root
problem, the sewer line must be replaced completely.
