What is a Sewer Main Drain?
A sewer main drain is an underground pipeline that exits a building’s sewage. It is a large and wide pipe consisting of durable material. It takes wastewater from bathrooms, toilets, etc., and drains them into the city’s sewer line. It is a crucial component of a city’s sanitation infrastructure. The main drain ensures all sewage is taken to treatment facilities.
The material of Sewer mains is durable, like concrete, iron, or plastic. They range in diameter from 6 inches to over 12 feet. They are underground and are present beneath city streets, alleys, or public rights-of-way. The sewer main connects to smaller pipes, known as lateral pipes. They carry wastewater from individual buildings to the main sewer line.
Sewer mains rely on gravity to move wastewater downhill to the treatment plant. They have a slight downward slope to ease the flow of water. Sometimes, we use pumps to help move wastewater through the pipes. The sewer main drains have a cleanout in houses. It provides easy access to maintain the plumbing system.

Place the plunger’s rubber cup over the toilet drain, ensuring it forms a tight seal. The rubber cup should completely cover the drain opening. Add enough to cover the plunger cup if the toilet bowl has no water. It will create a vacuum seal when you start plunging.

If the water begins to drain, flush the toilet to see if the clog has been out. If not, repeat the plunging process until you remove the clog. Once you do it, flush the toilet several times to ensure the water drains correctly. Remove the gloves and clean the plunger and surrounding area with soap and water.
