What Does Lateral Drain Mean In Construction?
A lateral drain is a section of pipe that is positioned outside the boundary of a building. It may be located under a public pavement or road and either connects to a neighbour’s drain or connects directly to a public sewer.
A lateral drain carries wastewater and excrement away from a multi-occupant building, such as an apartment complex.
The private sewer lateral (PSL) is the underground pipe on your property that connects the home’s plumbing to the municipal sewer main.
The PSL is typically divided into two parts: upper and lower laterals. The upper lateral runs from the sidewalk to the house and is usually considered the homeowner’s responsibility.
Drain mapping can help identify any potential trouble areas of a drain or sewer system, including private and lateral drains.
This can help reduce the possibility of errors in identifying private and lateral drains.
How To Install Lateral Drains?
Installing a lateral drain requires several steps, including determining the length and elevation of the pipe, taking measures to prevent or minimize disturbing existing water lines or other public or private sewer systems, and obtaining necessary permits.
The lateral pipe is typically 4 inches in diameter and connects a building’s plumbing system from the foundation to the public sewer main.
It is important to replace older sewer laterals as they are typically made of clay with cement mortar joints that can crack and separate, leading to ground water leaking into sewer mains.
Property owners may choose to tackle the sewer connection job themselves if it is all on private property, but it is recommended to contact several contractors for free estimates before beginning the project.
What Materials Are Used For Lateral Drains?
Materials for lateral drain installation vary depending on the type of installation and the desired outcome.
Common materials used in residential sewer line installations include Polyvinyl Chloride (PVC) pipe, Acrylonitrile Butadiene Styrene (ABS) pipe, High Density Polyethylene (HDPE) pipe, clay pipe, and fabric sock.
PVC and ABS pipes are lightweight and easy to cut, while HDPE is strong and semi-flexible. Clay pipes are difficult to install and are subject to cracking and root intrusion.
Fabric socks can be used to cover connections between pipes for additional protection.
For linear drains, Infinity Drain recommends using a traditional clamping drain body for PVC/Vinyl Liner, Rubber Liner, Lead Pan, Copper Pan, Fiberglass, and Hot Mop type waterproofing.
The diameter of the drain should be determined based on the size of the tile being used as well as the desired outcome of the installation.
For threshold installs, it is recommended that the drain run wall-to-wall to block any water from leaving the shower or wet area.
How You Should Maintain A Lateral Drain?
To maintain a lateral drain, it is important to limit food waste going down the kitchen drain line, flush the plumbing system regularly, and naturally clean the plumbing system.
Additionally, it is important to address sewer issues quickly and clear out tree roots that may be causing blockages.
Property owners should also inspect and keep their lateral in good working order, as well as check for any obstructions in the public sewer or sewer lateral between the curb and sewer main.
Finally, property owners should consider installing a backwater valve and ensure that it is operating properly at all times.
