What lasts longer for piping PVC or galvanized steel?
Regardless of the material, each of these plumbing products have a life span that you should know so you can gauge whether you need an upgrade. Brass, cast iron, and galvanized steel have a life span of 80 to 100 years, copper lasts 70 to 80 years, and PVC piping only survives for 24 to 45 years.
How long does PVC pipe last in the sun?
As a general rule, PVC pipe will last 50 to 80 years in the sun. Interestingly, the sun does not affect PVC negatively in any way. The lifespan of PVC pipes is estimated at 50 to 80 years. So PVC pipe will last a long time in the sun.
Do you need to replace galvanized steel plumbing pipes?
If your home, business, apartment complex or condo building still contains galvanized steel plumbing pipes, you may be wondering if you should replace the entire system, due to the potential hazards and water pressure problems, or if those pipes can be relined with an epoxy coating or liner.
How to replace a galvanized drain line with PVC?
Make two cuts, one near each coupling. Remove the corroded pipe. If you plan to connect to an existing PVC farther down the drain line, cut the galvanized pipe and then cut near the closest end of the PVC pipe. Set two pipe wrenches one to hold and one to turn, to remove both couplings. This leaves two male-threaded ends.
Is it OK to mix PVC and CPVC pipes?
You install PVC and CPVC pipes the same way, but you should not mix them. When replacing old galvanized pipes, it’s a good idea to cut out and replace as many of the old pipes as you can. Galvanized pipes tend to corrode with age, which restricts flow and makes them vulnerable to leaking.
What causes a galvanized drain pipe to corrode?
Galvanized drain pipes corrode from the inside. Because rust builds up inside the pipe, its inner diameter becomes smaller with time, leaving less area for drainage. Jagged edges caused by the corrosion also impede flow by catching waste and causing blockages.
What should I replace my galvanized water pipe with?
Although galvanized pipes are coated inside and out to prevent rust, they rust inside and will corrode over time, causing a build-up that restricts the flow of water, and/or the pipe may leak. Galvanized pipes are typically replaced with PEX, PVC-CPVC or copper pipes.

Why are galvanized steel pipes used in homes?
Galvanized steel pipes were common in U.S. homes until copper became popular in the 1950s and 1960s. Although galvanized pipes are coated inside and out to prevent rust, they rust inside and will corrode over time, causing a build-up that restricts the flow of water, and/or the pipe may leak.
