Here, we’re interested in discussing the inlet pipe that brings in or channels waste into the septic tank. Readers seeking to learn how to pipe from a house to a septic tank will find this article interesting.
We’ve provided detailed information about the whole process. All you need to do is read on to discover how.
If you are already facing septic problems, you may consider repiping the whole house.
Piping Septic Line From House To Tank
When installing a septic tank, such installation is never complete without completing the necessary connections.
Connections in this sense refer to the inlet and outlet pipes. The inlet drain pipe brings in waste from the house while the outlet pipe goes extends from the tank to the drain field.
Who Performs the Task?
Before we get into any details on how to pipe from house to septic tank, it’s necessary to make certain things clear.
First, the process of installing a septic system is delicate. Every process must be carefully implemented to guarantee smooth operations.
Secondly, the quality of installation rests entirely on the expertise of your installer. This is a key requirement that must be carefully addressed. Are you interested in handling this task the DIY way?
Such action may be quite risky as any mistake could cost you lots of money in repairs due to developing problems.
It’s important to seek the help of an expert when piping from the house to the septic tank. However, learning about the process is a plus as you get to better appreciate the installation procedure carried out by an expert.
Key Parts of a Sewage Disposal System
Connecting a pipe from a house to a septic tank requires knowing different parts of a septic system.
There are 5 main parts of a sewage disposal system. These include the house plumbing, the sewer line from the house to the tank, and the septic tank.
Other parts include the septic tank outlet sewer drain pipe and the drain field or leach field. Of all these components, the sewer line or pipe leading from the house to the tank is of greater interest.
Why Connect the Drain Pipe from the Building to the Tank?
It goes without saying that wastewater being produced by a household needs to be channeled out. Whether such wastewater is coming from the toilet, kitchen or bathroom doesn’t matter.
All of it has to be drained out to a treatment area.
This is where the septic tank comes into play. The tank is a key component of the septic system and serves as a holding facility where wastewater is held long enough to separate into three distinct layers.
These layers include the scum which floats at the top, followed by the effluent layer.
The sludge layer is found at the bottom of the tank and consists mainly of solids. Effluent seeps out of the tank through an exit drain pipe which transports it to the drain field for further treatment.
Explaining this procedure has been necessary to help understand the workings of the system.
Now, without the pipe connecting a house to a septic system, all of the above processes won’t be possible. In other words, wastewater treatment is never possible without a fully functional septic system.
This indispensable part (pipe) of the system needs to be in place.
Connecting A Drain Pipe From A House To A Septic Tank
There needs to be a pipe for septic tanks to have an inflow of wastewater. The installation of this pipe is what we’ll be dwelling on. The pipe connecting a house to the septic tank is known as the inlet pipe.
Now, most septic tanks come with preinstalled baffles. As expected, there are two baffles installed in the tank, the inlet and outlet baffles. The drain pipe coming from a building will need to be connected to the inlet baffle.
In most cases, a 4-inch sanitary tee fitting connects such pipes.
Not all septic tanks come with preinstalled baffles. For these, you’ll need to have them installed before having your pipes connected to the septic tank.
Drain pipes coming from the house should be installed in such a way that they slope toward the tank.
The distance of a septic tank from a building will determine how deep it’s dug into the ground. This is mainly due to the downward slope needed for the pipe to enter into the tank. Such a downward slope enhances the action of gravity in conveying wastewater from a house into the septic tank.
The farther the tank is from a building, the deeper the pipe needs to go into the ground. The reverse is true for situations where the tank is closer to the house or building.
The inlet to a septic tank is normally located at the top. This inlet measures about 4-inch. Now, for a pipe to be connected from a house, it should maintain about ¼-inch per-foot slope towards the septic tank.
For a better picture of how the pipe installation will unfold, you’ll need to look at the distance of the septic tank from the house. Every 10 feet of distance between the septic tank and the building will require a depth of around 2 ½ inch below the point from which such pipe emerges from the house.
More Installation Guide
Quite a lot of digging goes on when installing a septic system. There’s a need to dig a hole for the septic tank, as well as a trench that conveys the drain pipe from the tank to the leach field.
The leach field also needs to be dug including the trench for the septic pipe leading from the house.
It’s much better and easier to have the trench for the pipe dug before digging the hole for the septic tank. This helps prevent a situation where the tank obstructs the process.
One of the most commonly used digging tools for such a trench is the backhoe.
The entire installation process gets easier when a professional is involved. Septic system technicians fully understand the procedure and carry out the process without delay.
Knowing how to pipe from a house to a septic tank is invaluable for persons seeking to perform an installation task themselves.
However, we recommend the input of a professional as it makes the job more reliable.
This will prevent drainage problems and the cost that comes with burst pipe repairs.
