  How Basement Drains Work

Basement drains provide an effective way to eliminate excess water from your home. Many properties have drained installed in their basements, preventing water damages to the houses and their contents. Although basement drains are more common back then, many modern homes still utilize this type of drainage system due to its efficiency. Basement drain systems work passively, their designs primarily based on the law of physics.

Basic Mechanics

The way basement drains work is quite simple. Gravity naturally transfers water from the house to the lowest point where it is then drained. Basement drains are installed at the floor’s lowest point, making use of slopes to efficiently transport water out of the house. Once the drain has collected water through the help of gravity, the water is then transported into a sewer system and then combines with wastewater from other drains present in the system.

For properties that have septic tanks, some basement drains may lead to dry wells, drainage ditches, or leach fields instead, to prevent flooding the septic system. Nowadays, some basement drain, modern designs use pumps to move water more effectively Preventing Gas Infiltration

Certain components are considered indispensable parts of basement drains – drain traps and clean out plugs.The drain traps used for basement drain are similar to those used under bathroom or kitchen fixtures. The drain pipe, which resembles a ‘U’ in shape, is constantly filled with water even if the water is not running.

Drain traps help by preventing sewer gases from getting into your home. These traps usually require you to have a vent that leads outside your property to maintain neutral air pressure within the system. This allows water to flow freely. Next, we have the clean out plugs.

These rubber stoppers are held in place by a wing bolt and nut. Clean out pertain to openings inside the basement drains that allow access whenever blockages happen.The clean out part of a basement drain is usually secured by a plug. However, clean out plugs can get damaged and rusted due to corrosion. When this happens, it is advised to have your plug replaced. Proper maintenance of both your drain traps and clean out plugs is essential to keep sewer gases from infiltrating your home.


If you ever experience a clogged basement drain, the process of unclogging it is not different compared to the other pipes. Blocked basement drains are first unclogged using a plunger. If this doesn’t work, removing the clean out plug is necessary. This will give the plumber better access to the drain. Expert plumbers have several advanced methods and are equipped with specialized equipment. The method they’ll choose depends on the severity of your clog problem. In some cases, a water hose may be inserted into the drain to flush the debris out
