Guide To Plumbing Line Materials For Your New Home

Posted on: 22 February 2021

When you are building a new house, eventually your plumbing contractor will need you to make a decision on the water lines — plastic or metal. There are then further options within these two broad categories.

Water Lines

There are three main options to consider — rigid plastic, flexible lines, or metal. Rigid plastic water lines are typically made of PVC or PEX. PVC is the least expensive option, but it is only suitable for cold water lines, as hot water will eventually degrade it. PEX is more flexible than PVC and can withstand heat, so it is typically used for hot water lines or for all of the water lines.

Flexible lines can be made of plastic or metal. They are best reserved for uses where flexibility is needed, such as a sink sprayer or shower head, since they aren't as durable. Metal water supply line are usually copper, a durable material that can last a life time. Just keep in mind that copper is one of the more expensive water line options.

Drain Lines

The drain lines in your home are typically made of galvanized steel or PVC. Traditionally steel was preferred since it is durable and corrosion resistant. The problem is that it isn't corrosion-proof. As it ages, scratches in the finish leave it prone to rust and corrosion, which means leaks can spring up.

Generally, PVC is the standard option for drain lines throughout your home. These pipes are smooth and won't corrode, so leaks are rare and the lines drain easily. PVC is also inexpensive, so when repairs are necessary, the replacement of a failed length of pipe isn't likely to break the bank.

Main Sewer Line

The choices for the material used for your main sewer line may be limited by local codes and regulations. Almost all modern main sewer lines must be made of plastic, typically ABS or PVC. If your home is built on a lot that previously had construction on it, your new line may then hook into an older line made of clay or cast iron. Your plumber will have to inspect the old line to see if it is functional or requires replacement.

It is possible in some locations to opt for cast-iron sewer pipes, but this is generally more expensive than the plastic options. Cast iron is also more prone to root incursion, so it rarely recommended. The main benefit to cast iron is that it is less likely to break in areas where there is a lot of soil movement.
