If your home still has galvanized steel piping, you’re not alone—many Long Beach houses built before the 1960s do. But is it time to replace them? The short answer: if you’re seeing low pressure, rusty water, recurring leaks, or you’re planning a remodel, replacement is usually the smartest move. Here’s a practical guide A1 Best Plumbing and our Long Beach Plumbing experts recommend to help you decide confidently.
Quick answer: When to replace galvanized pipes
- Replace now if you have: persistent low water pressure, brown/discolored water, frequent pinhole leaks, or pipes older than 50 years.
- Consider soon if you’re remodeling, upgrading fixtures, or adding bathrooms—old lines may not support modern demands.
- Monitor/test if you’re unsure: get water quality testing and a plumbing inspection to assess corrosion and flow.
In most older Long Beach homes, our Long Beach Plumbing experts recommend a planned whole-home repipe rather than reactive, piecemeal repairs that add up.
What are galvanized pipes—and why they fail
Galvanized pipes are steel pipes coated with zinc to slow rusting. Over decades, that zinc layer wears off. Inside the pipe, minerals and corrosion create rough buildup (tuberculation) that:
- Restricts flow, causing low pressure at showers and sinks
- Flakes rust, leading to brown or yellow water
- Weakens pipe walls, resulting in leaks—often at threads and elbows
- May introduce lead, since older galvanizing and upstream lead components can trap and release lead particles
Because corrosion happens from the inside out, pipes can look fine from the outside and still be near failure within.
Signs it’s time to repipe
Our Long Beach Plumbing experts recommend using this checklist:
- Water pressure drops when multiple fixtures run
- Discolored water, especially after water sits overnight or after street work
- Frequent leaks or damp spots along walls/ceilings
- Inconsistent hot water or clogged aerators due to rust flakes
- Visible corrosion at exposed sections, unions, or the water heater connections
- Homes built before 1965 that have never been repiped
Pro tip: Remove an aerator and check for rust flakes. Also, a magnet sticks to galvanized steel but not to copper; this helps identify pipe type where it’s visible.
How to confirm the condition of your pipes
Before committing, our Long Beach Plumbing experts recommend:
- Static and dynamic pressure tests to see how flow drops under demand
- Water quality testing for iron, lead, and turbidity
- Camera inspection at accessible sections and manifolds
- Assessment of service line from the meter to your home—often overlooked and often galvanized too
A1 Best Plumbing provides data-driven assessments so you can see exactly what’s happening inside your system.
Replacement options: PEX vs. copper (and where each fits)
Choosing the right material matters for performance, budget, and insurance acceptance.
- PEX (cross-linked polyethylene)
- Pros: flexible (fewer fittings), faster install, great for seismic resilience, resistant to scale, cost-effective
- Cons: must be protected from UV and rodents; quality and fitting selection matter
- Best for: whole-home repipes in finished homes where minimizing drywall cuts is a priority
- Type L Copper
- Pros: long service life, heat-resistant, excellent for exposed/mechanical rooms, widely accepted by insurers and inspectors
- Cons: higher cost, more fittings, can scale up in hard water if not treated
- Best for: partial replacements, exterior runs, water heater rooms, and where homeowners prefer metal
- CPVC is less common for whole-home repipes locally due to temperature/impact limitations.
Many Long Beach homes use a hybrid approach—copper near the water heater and exterior, PEX in walls/ceilings. Our Long Beach Plumbing experts recommend dielectric unions when transitioning between metals to prevent galvanic corrosion.
Costs, timelines, and what to expect
Every home is different, but typical Southern California ranges:
- PEX whole-home repipe (1–2 baths): often in the $6,000–$15,000 range
- Copper whole-home repipe (1–2 baths): often in the $8,000–$20,000 range
- Larger homes, complex layouts, and add-ons (e.g., new hose bibs, recirculation lines, whole-house filtration) increase costs.
Timeframes:
- PEX repipe: 1–3 days for piping, plus 1–2 days for drywall patch/texture/paint
- Copper repipe: 2–5 days for piping, plus finishing
A1 Best Plumbing provides clear, line-item estimates and schedules so you know exactly what’s happening and when.
Long Beach-specific considerations
Local conditions influence whether our Long Beach Plumbing experts recommend replacing now or soon:
- Water hardness: Long Beach water tends toward moderately hard, which accelerates scale buildup in galvanized and can impact copper over decades.
- Seismic activity: Flexible systems (PEX) with proper supports and seismic strapping can better tolerate movement.
- Aging housing stock: Neighborhoods like California Heights, Wrigley, and Belmont Heights often still have original galvanized—an inspection is prudent.
- Permitting and code: Repipes typically require a plumbing permit and inspection by Long Beach Development Services. A licensed C-36 contractor should handle permits and code updates (e.g., bonding, seismic strapping at the water heater).
- Lead awareness: If walls with pre-1978 paint are opened, EPA Renovation, Repair and Painting (RRP) practices apply.
A licensed local plumber ensures compliance and smoother inspections.
Partial repair vs. whole-home repipe
It’s tempting to replace only the “bad” sections. Here’s the trade-off:
- Partial repairs
- Pros: lower upfront cost, faster
- Cons: old sections keep failing, mixed-material connections can corrode, uneven pressure and water quality persist
- Whole-home repipe
- Pros: consistent pressure/quality, lower leak risk, better resale value, fewer emergency calls
- Cons: higher initial investment, short-term disruption
When multiple symptoms are present, our Long Beach Plumbing experts recommend a planned whole-home repipe over repeated spot fixes. If budget is a concern, a staged repipe (e.g., start with main trunk and high-use bathrooms) can be a smart middle path.
How to prepare for a repipe
To minimize disruption, our Long Beach Plumbing experts recommend:
- Schedule around your routine; we’ll maintain temporary water wherever possible
- Clear access under sinks, in closets, and near the water heater
- Decide finishes for drywall/paint patching ahead of time
- Consider upgrades while walls are open: new shutoff valves, pressure regulator, hose bibs, recirculation line, whole-home filtration
- Plan for flush-out after installation to remove any debris and air
