Sewer Drain Pipe

One of the most critical components of a functional sewer system is the sewer drain pipe. This pipe carries waste from your home’s plumbing system to the municipal sewer system.

This article will discuss everything you need about sewer drain pipes, including their function, materials, and common problems.

What is a Sewer Drain Pipe?

A sewer drain pipe is a vital component of your home’s plumbing system that carries wastewater away from your home to the municipal sewer system.

Without this vital pipe, all the wastewater you generate from your sink, shower, and toilets would be stuck at home – creating a disastrous situation!

Sewer drain pipes are located underground. They are made from durable materials to withstand constant and continuous wastewater flow.

Usually made of materials like PVC, cast iron, and clay, these sturdy pipelines are designed to cope with the pressure from below!

Different Types of Sewer Drain Pipes

Can’t make up your mind between clay, plastic, or metal? The decision can be tough when choosing the right sewer drainage pipe.

PVC (Polyvinyl chloride) pipes are the go-to for residential plumbing. They’re lightweight, durable, and won’t rust or give in to chemicals – plus, they don’t require much effort to install.

Cast Iron Pipes

Cast iron pipes are famous for older homes — and with good reason! They’re tough as nails, lasting many years without difficulty.

But you must be prepared when it comes time to install them: they may weigh more than other materials used in sewer drain pipe systems.

Clay Pipes

Although clay pipes were the go-to for sewer drains not too long ago, they’ve been rendered obsolete thanks to their vulnerability and tricky repair process.

Nowadays, PVC or cast iron are preferred over clay as these materials offer more durability and ease of fix!
