Understanding Standard Plumbing Pipes Used in Houses

The types of pipes used in residential plumbing systems have evolved significantly over the years

Pipes supply hot or cold water to the different plumbing fixtures and appliances and transport wastewater to the sewage system. The types of pipes used in residential plumbing systems have evolved significantly over the years. Modern pipes consist of several durable and lasting materials, unlike in the past when homeowners only had limited options.

Understanding different types of plumbing pipes can help homeowners in proper plumbing system maintenance and address issues correctly. Depending on the age of the house, here are the standard pipes commonly found in homes:

PVC pipes

PVC, or polyvinyl chloride, is a highly popular home plumbing pipe seen as an alternative to traditional pipes. It is commonly used for drain and vent piping. PVC pipes are highly versatile, lightweight, affordable, and easier to install, maintain, and repair. These pipes are strong, durable, and resistant to rust, corrosion, and blockages, which gives them an edge over their metal counterparts. PVC pipes can handle high-pressure water, making them suitable for use as the main water supply line.

PEX pipes

PEX, or cross-linked polyethylene, is flexible plastic piping that emerged in the late 1990s. Its durability, affordability, and high functionality made these pipes immensely popular for water supply lines. A PEX plumbing system has an average lifespan of over 50 years. It does not rust or corrode and comes in two colors, blue for cold water and red for hot water. PEX pipes need not be joined or segmented, which reduces the risk of line breaks and leaks.

ABS pipes

Acrylonitrile butadiene styrene (ABS) is a plastic plumbing pipe identified by its black color. They are used for drain and waste piping. ABS pipes are budget-friendly, easy to install, durable, and resilient to cold temperatures and rust. But their susceptibility to damage due to UV rays makes them unsuitable for exterior use.

Cast iron and galvanized steel pipes

Older homes built in the early 20th century used cast iron pipes for sewer and drainage and galvanized steel pipes for water supply. Plumbers rarely use them in new construction. Galvanized pipes are malleable but heavy and difficult to repair and replace. Furthermore, cast iron pipes are durable but brittle and prone to rust.

Copper pipes

Copper pipes are standard within the plumbing industry and found in several old and new homes in America in showers, tubs, and sinks. It is reddish-brown and can last for over 50 years. Copper pipes are durable, withstand high water pressure, and tolerate hot and cold water. Copper pipes are available in varied thicknesses and are corrosion-resistant and environmentally friendly.

Flexi pipes

Flexi (flexible) pipes usually consist of stainless steel and are available in different sizes and lengths. Plumbers generally use them for final piping connections for toilets, sinks, and water heaters. Experts advise against using these pipes inside floors or walls. They are expensive and can fail due to wear and tear over the years.
