PEX vs Copper vs PVC for Tampa Repiping
If you’re replacing galvanized pipes in your older Tampa home, the big question is: PEX, copper, or PVC? Here’s the real-world comparison.
Quick Verdict
For Tampa repiping: PEX wins for most homes ($4,500-$8,500 installed), cheaper, faster, handles hard water, 30-50 year lifespan. Copper for premium + long-term ($7,500-$12,000+), 70+ year lifespan, fire resistant, higher resale value. PVC only for drain lines, not water supply. Call (813) 343-2212.
PEX vs Copper vs PVC
| Factor | PEX | Copper | PVC |
|---|---|---|---|
| Used for water supply lines | Yes | Yes | No (PVC is for drains) |
| Typical Tampa whole-home repipe | $4,500 – $8,500 | $7,500 – $12,000+ | N/A for supply |
| Lifespan | 30-50 years | 70+ years | N/A |
| Install time | 2-3 days | 5-7 days | N/A |
| Hard water resistance | Excellent | Good (can pit over decades) | N/A |
| Flexibility (fewer joints) | Very flexible | Rigid | Rigid |
| Freeze resistance | Better (flexes) | Can burst | Can crack |
| Fire resistance | Poor (melts) | Excellent | Poor |
| UV resistance | Poor (shielded install) | Excellent | Good |
| Resale value impact | Neutral/slight positive | Positive (some buyers) | N/A |
| Code approved (Florida) | Yes | Yes | Supply: No. Drains: Yes |
Florida-Specific Considerations
Tampa-specific considerations:
- Hard water (7-10 grains/gal): PEX handles this best, no corrosion or mineral pitting. Copper can pit slowly over decades.
- No freeze concerns: Tampa rarely freezes, so PEX freeze-flexibility isn’t as valuable here as in northern states.
- Attic runs common: PEX stays flexible in hot attics. Copper is fine but requires expansion loops for temperature changes.
- Existing galvanized: Pre-1990 Tampa homes often have galvanized steel supply pipes. These corrode internally, reducing pressure and adding rust. Both PEX and copper are vastly better replacements.
- Resale in Tampa: Local market generally fine with PEX. Some luxury buyers prefer copper. Neither hurts resale significantly.
What We Recommend (and Why)
Our Tampa repiping advice:
- Pick PEX ($4,500-$8,500) for: average-budget homes, faster install, first-time replacement of galvanized, most practical choice. 30-50 year lifespan covers most ownership spans.
- Pick copper ($7,500-$12,000+) for: luxury homes, 30+ year stays, pride-of-workmanship owners, high-humidity insulation concerns, or neighborhoods where copper is expected.
- PVC is NOT a supply line option in Florida, code doesn’t allow it for potable water. PVC is excellent for drain lines only.
- CPVC (similar to PVC but for hot/cold supply), allowed in Florida but rarely chosen anymore. Brittle and prone to leaks over decades. We don’t recommend.
Most of our repipes are PEX. Best value for Tampa homes. Copper for the rare high-end requests.
FAQ
How do I know if I need repiping?
Signs: multiple pipe leaks in 3-5 years, rusty/discolored water, low pressure whole house, pre-1990 home with original galvanized pipes.
Can I repipe partially?
Yes, but not typically cost-effective. Once you’re opening walls, doing the whole home is marginal cost more and avoids future partial failures.
Do I need to move out?
No. Water off 4-8 hours/day during active work; restored each evening. Live in the home.
Who fixes the drywall?
Separate contractor. Plan for $1,500-$3,500 additional drywall patching/painting after repipe.
PEX toxicity rumors?
Well-studied. EPA-approved for drinking water. No leaching issues with modern PEX (PEX-A, PEX-B). Safer than some alternatives.
Copper vs PEX for insurance discount?
Some insurers offer small discounts for full repipe (either type). Copper occasionally favored. Check with your agent.
How long does a repipe take?
PEX: 2-3 days. Copper: 5-7 days. Includes access cutting, running new pipes, tying into fixtures, pressure testing.
