Repipe & Pipelining in San Diego, CA
Rusty water, weak pressure, and pinhole leaks mean your old pipes are failing from the inside. A&A Plumbing replaces galvanized, polybutylene, and worn copper lines with PEX or copper — or lines them trenchlessly — with clear upfront pricing.

Stop Patching Old Pipes and Fix the Whole System
Many older San Diego homes still carry their original supply lines, and that pipe has been failing for decades. Galvanized steel and polybutylene lines corrode and scale from the inside out; a line that started near 3/4 inch can narrow to under 1/4 inch from rust, choking flow to every fixture.
Symptoms show up at your taps: rusty or metallic-tasting water, low pressure throughout the whole home, recurring pinhole leaks, discolored laundry, and banging pipes. Several together usually mean a repipe, which fixes the problem at its source instead of patching it again.
Our Repipe & Pipelining Services
Whole-Home Repiping
Replace every failing supply line in one project and restore full pressure throughout the house.
Scope your repipe →PEX Repiping
Flexible PEX resists scale and freezing, installs quickly, and uses fewer fittings — the most cost-effective repipe for most homes.
PEX repiping →Copper Repiping
Durable, time-tested copper delivers long-term reliability and strong resale value.
Copper repiping →Trenchless Pipe Lining
We coat the inside of existing pipes with an epoxy liner instead of tearing out walls.
Trenchless lining →Pinhole Leak Repair
Thin copper and hard water cause pinhole leaks that keep returning. We repair them and say when a repipe is the better spend.
Pipe repair costs →Slab Leak Repiping
When a leak under the foundation cannot be patched, we reroute the line overhead and cap the buried pipe.
Slab leak repiping →PEX vs. Copper: Which Repipe Is Right for You?
Both materials last decades, so the choice comes down to cost and priorities. PEX is flexible, resists scale and freezing, installs faster, and costs less. Copper is durable with strong resale appeal but costs more. A whole-home repipe runs about $4,500 to $15,000, and most homes are finished in three to five days. Because San Diego water is hard, pairing a repipe with a water softener protects the new pipes.

| Flexibility | Flexible; fewer fittings and joints | Rigid; more joints and labor |
| Scale & freeze | Resists scale and freeze damage | Can scale and split in a freeze |
| Install time | Faster; often 3 to 5 days | Slower; more labor-intensive |
| Typical whole-home cost | $4,500 – $9,000 | $9,000 – $15,000 |
| Lifespan | 50+ years | 50+ years |
| Best for | Budget-conscious and older homes | Classic reliability and resale appeal |

How do I know if my San Diego home needs a repipe?
Watch for rusty or metallic-tasting water, low pressure throughout the whole home, recurring pinhole leaks, discolored laundry, and repairs that keep coming back. In older San Diego homes, galvanized steel and polybutylene are the usual culprits. Several together almost always mean a repipe.
How much does a whole-home repipe cost in San Diego?
Most whole-home repipes in San Diego run about $4,500 to $15,000 depending on the home's size and the material. PEX sits at the lower end; copper at the higher end. We inspect your system and give you a written, upfront price before any work begins.
How long does a repipe take?
Most San Diego homes take about three to five days. PEX moves faster because the flexible lines need fewer fittings, while copper takes a bit longer. We protect floors and furnishings and give you a clear schedule.
Is PEX or copper better for my home?
Both last 50 years or more, so it comes down to cost and priorities. PEX is flexible, resists scale and freezing, installs faster, and costs less. Copper is classic and durable with strong resale appeal but costs more. We will explain the trade-offs for your home.
