When Is the Best Time to Replace Old Plumbing Pipes?

March 31, 2025

Over time, even the most reliable plumbing systems begin to wear down. If you're a homeowner, knowing when to replace old plumbing pipes can help you avoid major water damage, costly repairs, and unexpected emergencies. But how do you know when it’s time to make the switch? At City Plumbing and Rooter, we help homeowners across Arizona recognize the signs of aging pipes and make smart, timely upgrades to their plumbing systems.

Signs Your Pipes May Need Replacing

Not all plumbing issues require a full replacement—but some do. Here are some common red flags that your pipes may be past their prime:

Frequent Leaks: Occasional drips are normal, but if you're dealing with constant leaks, it’s a sign that your pipes are deteriorating.

Discolored Water: Brown or rusty water can indicate corrosion inside your pipes, especially if you’re using galvanized steel or iron piping.

Low Water Pressure: Buildup inside old pipes can restrict water flow, causing poor pressure in your showers and sinks.

Strange Noises: Banging, clanking, or gurgling sounds in your pipes often suggest trapped air, sediment, or failing components.

Visible Corrosion: If you notice flaking, rust, or green stains around exposed piping, it's a good idea to have a professional take a closer look.

Pipe Material Lifespans

The age of your plumbing system also plays a big role in determining when to replace it. Different materials have different lifespans:

Galvanized Steel: 20-50 years

Brass: 40-70 years


Copper: 50+ years

PVC: 25-40 years

If your home was built several decades ago and hasn’t had a plumbing upgrade since, chances are your pipes are nearing the end of their usable life.

Best Time of Year to Replace Plumbing Pipes

In Arizona, the milder winter and spring months—typically between November and April—offer ideal conditions for plumbing replacements. Cooler temperatures make it easier to work in crawlspaces and attics, and scheduling during these months may help you avoid peak-season delays. That said, City Plumbing and Rooter offers year-round pipe replacement services and can work with you to find the most convenient time.

Don’t Wait for a Plumbing Disaster

Replacing your old plumbing pipes may feel like a big investment, but it can save you thousands in water damage repairs and provide peace of mind. If you’ve noticed signs of pipe failure or simply want a professional opinion, City Plumbing and Rooter is here to help. Our licensed Arizona plumbers can inspect your system, walk you through your options, and complete replacements with minimal disruption to your home.
