While a plumbing system’s pipes can last for decades, several factors that can impact their lifespan. This includes piping material, maintenance frequency, water quality, and temperature fluctuations. Let’s take a closer look at how often homes need to be repiped.
Average Lifespan of Common Pipe Materials
Galvanized Steel:
You can expect galvanized steel pipes to last up to 50 years. Unfortunately, this type of piping material is more prone to experiencing premature corrosion. Leaks can occur sooner than expected in certain environments.
Plastic:
Many of today’s homeowners are opting to have PVC and PEX pipes installed. Not only are these plastic materials strong and durable, but they are also non-toxic. Modern PVC and PEX pipes can last up to 100 years.
Copper:
Copper is currently the most widely used piping material for residential homes. Although copper can be on the expensive side, it’s far more resistant to corrosion than some other metals. The average life of copper pipes typically surpasses 50 years.
Cast Iron:
Cast-iron pipes are very rarely used in modern homes. While cast iron is tough, it has a tendency to suffer from mineral buildup. Rust is also a big problem associated with cast-iron pipes. Nevertheless, cast iron can last upwards of 70 years under the right conditions.
Brass:
Because brass pipes were deemed to contain trace amounts of lead, they ceased being recommended for use by some plumbing professionals. However, the life expectancy for brass pipes is between 80 and 100 years.
Signs Your Home Needs Repiping
1. Recurrent Leaks
If your plumbing pipes have started to experience recurrent leaks, consider whole-home repiping. While leaks can be repaired, it’s only a matter of time before another one occurs. Not only can leaky pipes cause structural damage to your house, but they also promote the growth of mold and mildew.
2. Discolored Water
Discolored water should immediately raise a red flag. It’s a health hazard that needs to be addressed right away. Older pipes made of certain metals are especially prone to rusting. The only solution is to upgrade your piping.
3. Low Water Pressure
When there’s heavy mineral buildup within your pipes, low water pressure tends to occur. To find out the definite cause of your home’s reduced water pressure, be sure to contact a licensed professional such as Benjamin Franklin Plumbing. Faulty plumbing components, such as pressure regulators and water valves, can also cause reduced pressure.
4. Odd Noises
Noisy pipes should get your attention. Gurgling often stems from a clogged drain. Banging and rattling sounds can also be produced by deteriorating pipes.
