Replacing Galvanized Steel Pipes: PEX and PVC Lead the Way

Repiping in Urbana, IL

For a long time, galvanized steel pipes were the standard for plumbing systems, but now, PEX and PVC are becoming the top choices. These newer materials have a lot of benefits over steel, like being more flexible, easier to install, and resistant to corrosion. At Dogtown Heating, Air & Plumbing in Urbana, IL, we’re here to explain why switching to PEX or PVC might be the best decision for your home’s plumbing needs.

Problems with Galvanized Steel Pipes

Galvanized steel pipes used to be the standard in plumbing, especially for homes built before the 1970s. These pipes are coated with zinc to protect them from rust and corrosion. However, over time, the coating begins to break down. This can cause several problems in your home, such as reduced pressure, water discoloration, and even clogging.

You may have already noticed some of these issues if you live in an older home with galvanized steel pipes. Rust buildup can cause your water to have a brownish tint, which is not what you want from your faucets. Furthermore, corrosion inside the pipes can cause leaks over time, leading to expensive water damage in your walls or ceilings.

Why PEX and PVC Are Better Choices

As technology has improved, plumbing materials have evolved. Today, PEX (cross-linked polyethylene) and PVC (polyvinyl chloride) pipes are replacing galvanized steel for many reasons. One of PEX and PVC’s main advantages is their corrosion resistance. Unlike galvanized steel, which deteriorates over time, PEX and PVC won’t rust or corrode, ensuring that your plumbing system stays healthy.

In addition to being corrosion-resistant, PEX and PVC are easier to install. PEX pipes are made from flexible plastic, so they can bend and twist to fit into tight spaces without elbows and joints. This flexibility makes installation faster and cheaper because there’s less need for additional fittings and cuts. PVC pipes, while not as flexible as PEX, are still lightweight and easier to handle than heavy, rigid galvanized steel pipes. PEX and PVC can also be installed in smaller sections, making plumbing repairs or upgrades much simpler than dealing with large, rigid steel pipes.

PEX and PVC Pipes for Your Home

Now that you know the basic benefits of PEX and PVC, it’s important to understand which is better suited for various plumbing projects. PEX and PVC have their strengths but serve slightly different purposes.

PEX is a great choice for indoor plumbing because it’s super flexible. This makes it perfect for areas where pipes need to bend or fit into tight spaces, like in kitchens, bathrooms, and laundry rooms. It’s also great for underfloor heating systems because it can be easily laid out in long, continuous runs without worrying about joints and fittings.

On the other hand, PVC is often used for drainage and venting pipes. It’s more rigid than PEX, which makes it better for handling wastewater and venting gases. PVC is commonly used for sewer lines, downspouts, and outdoor plumbing. It’s also UV-resistant, meaning it can stand up to sunlight exposure if you need to run pipes outside. So, while PEX and PVC are both great choices for replacing old pipes, your plumber will choose one over the other, depending on where they will be used in your plumbing system.

Making the Switch to PEX or PVC

If you’re dealing with old, corroded galvanized steel pipes in your home, replacing them with PEX or PVC can be a smart decision. The process involves removing the outdated pipes and installing new ones, which might require some disruption to your home. However, the benefits of upgrading far outweigh the temporary inconvenience.

Working with a professional plumber will ensure the job is done right and that the new system is up to code. They can help you determine which material is best for each part of your plumbing system and make the transition as smooth as possible. When you upgrade, you’ll enjoy a reliable, low-maintenance plumbing system that will last decades, save you money, and keep your water flowing smoothly.
