Signs you need repiping include frequent leaks, discolored or rusty water, low water pressure throughout the house, visible corrosion on exposed pipes, and water that is only lukewarm or has a metallic taste. Repiping replaces your home's aging or failing water pipes with modern materials - and in older San Tan Valley homes stressed by hard water, it's sometimes the most cost-effective long-term fix. Here's how to know if it's time.
7 Signs You May Need Repiping
- Frequent or recurring leaks - once one section of old pipe fails, more usually follow.
- Discolored, rusty, or brown water from corroding pipes.
- Low water pressure throughout the home from scale and corrosion narrowing the pipes.
- Visible corrosion, flaking, or stains on exposed pipes.
- A metallic taste to the water.
- Older piping materials like galvanized steel or polybutylene.
- Water temperature or flow problems that persist after other fixes.
Common Repiping Materials
Modern repipes typically use PEX (flexible, affordable, resistant to scale - popular here) or copper (durable and long-lasting). The right choice depends on your home, budget, and preferences; a plumber can walk you through the trade-offs.
How Much Does Repiping Cost?
Whole-home repiping typically runs $4,000 to $15,000+, depending on the home's size, number of fixtures, pipe material, and how accessible the pipes are. While it's a significant investment, it ends the cycle of recurring leaks and repairs and protects your home from water damage.
Why Hard Water Makes Repiping More Common Here
San Tan Valley's hard water accelerates corrosion and scale inside pipes, which is why older local homes often need repiping sooner. Adding a water softener after a repipe helps protect the new pipes and extend their life.
