Should You Replace Galvanized Pipes When Remodeling? | Arlington, TX

Walk the blocks around West Sanford Street and Pirie Park and you’ll see what central Arlington does best: solid brick ranch homes from the 1950s, 60s and 70s on slab foundations, many still wearing their original plumbing. That plumbing is often galvanized steel, and it has a shelf life. If you’re planning a home improvement project in one of these houses, the pipes behind the walls deserve a decision before the new tile goes in.

Quick answer: If your Arlington home still has galvanized steel water lines, a remodel is usually the smartest time to replace them, because the walls and floors are already open. Galvanized supply lines typically last somewhere around 40 to 70 years, so a 1960s house near Pirie Park is at or past that window. Swapping them out during a kitchen or bathroom project avoids tearing into finished work a year or two later.

Key Takeaways

  • Galvanized pipes corrode from the inside: rust narrows the pipe and starves fixtures of flow long before a visible leak shows up.
  • The EPA notes that corrosion of older household plumbing is one way metals can end up in tap water, so this is a health question too.
  • Remodels open the walls anyway: replacing lines while the drywall is already out saves a second round of demolition and patching.
  • Slab homes usually get rerouted overhead: in much of Arlington, new PEX or copper runs through the attic instead of under the concrete.
  • A repipe is permitted work: in Arlington it goes through the city with inspections, and your contractor handles the paperwork.

How can you tell if your Arlington home still has galvanized pipes?

The quickest check is the exposed pipe at your water heater or under a sink: galvanized steel is dull gray, threaded at the joints, and a magnet sticks to it. Copper is reddish and smooth, and PEX is flexible plastic tubing, usually red, blue or white.

Many homes in this part of Arlington, especially the ranch houses between West Sanford Street and Ross Trail built before the mid 1970s, started life with galvanized supply lines. Some were partly updated over the decades, so it’s common to find copper near the water heater and old steel still feeding the far bathroom.

Symptoms tell the rest of the story. Brownish water first thing in the morning, weak pressure at the shower when someone runs the kitchen tap, and crusty threads on the pipe are all signs the zinc coating has given up and the steel underneath is rusting.

💡 Good to know: Mixed metals matter. When an old repair spliced copper straight onto galvanized steel without a dielectric fitting (a small insulating coupling), the two metals react and the steel corrodes even faster right at that joint. Crews check those spots first.

Why do galvanized lines fail faster in North Texas homes?

Heat, water chemistry and the way these houses were built all work against old steel pipe. Hot water speeds up corrosion, and a water heater in a baking Texas attic or garage keeps that side of the system working hard for decades.

Many homes in this part of Arlington sit on slab foundations poured over expansive clay. That clay swells in wet winters and shrinks in August, and the slab moves a little with it. Supply lines run under or through the slab take that stress at the threaded joints, which are the weakest point of a galvanized system. A slow leak under the concrete can run for months before anyone notices a warm spot on the floor or a water bill that doesn’t add up.

Then there’s the mineral content. Much of the region’s water runs hard, and the rough, rusted interior of an old steel pipe gives scale plenty to grab onto. A pipe that was three quarters of an inch wide when the house was built may now pass water through an opening closer to a pencil.

Older homes near O.S. Gray Natural Area often have cast iron drain lines too. They’re a separate system, but they age on a similar clock, and a remodel is a good moment to have both looked at.

Which material should replace galvanized steel: copper, PEX or CPVC?

For most Arlington repipes done during a remodel, PEX is the usual choice, with copper a close second where the homeowner prefers metal. CPVC still gets used, but less often for whole-house work.

PEX (cross-linked polyethylene, the flexible colored tubing) bends around corners, needs far fewer joints, and tolerates the freezes that catch North Texas off guard every few winters. Copper has the longest track record and handles heat well, but every joint is soldered, and in some water it can develop pinhole leaks. CPVC is rigid plastic that installs simply but gets brittle with age.

Material Typical service life Main strength Watch out for
PEX Often 40 to 50 years Flexible, few joints Must stay out of sunlight
Copper Often 50 years or more Proven, heat tolerant Pinholes in aggressive water
CPVC Often 40 to 50 years Simple to install Brittle with age
Galvanized steel Roughly 40 to 70 years Strong when new Rust, low flow, metal leaching

Those lifespans are general ranges from manufacturers and trade groups, not promises for your house. Water chemistry, installation quality and how hot your water runs all move the number. A good home improvement service in Arlington will walk you through the trade-offs in your own utility room rather than hand you a one-size answer.

Does replacing galvanized pipes in Arlington need a permit?

In general, yes. A whole-house or partial repipe is plumbing work, and in Arlington that kind of work is permitted and inspected through the City of Arlington.

That’s a good thing for you. An inspector checks that the new lines are supported, protected where they pass through framing, and pressure tested before the walls close up. Your contractor pulls the permit, schedules the inspections and meets the inspector on site, so your part is mostly letting them in. Requirements vary by city and change over time, so treat this as the general picture and let the crew confirm the specifics for your address.

Permits come up for most remodeling in Arlington anyway, so folding a repipe into a kitchen or bath project usually means one coordinated set of inspections instead of two.

Most repipes in these homes take a few working days, with the water off for only part of one of them. Here’s the typical sequence inside a larger home improvement project.

1
Walkthrough and flow checkThe crew traces the lines from the meter to each fixture, checks flow and pressure, and notes which sections are steel, copper or already replaced.
2
Plan the routeOn a slab home the new lines usually run through the attic and drop down inside walls. The plan marks where small access openings are needed outside the remodel area.
3
Permit and schedulingThe contractor files for the permit and lines up the rough-in inspection to land before the walls are closed, overlapping with demolition.
4
Run the new linesNew PEX or copper goes in while the old system stays live, so you keep water through most of the job. Attic runs are insulated against summer heat and winter freezes.
5
Switch over and pressure testThe main is off for a few hours while the new system is tied in at the meter and water heater, then pressure tested. Old lines are capped and left in place.
6
Inspection, patch and paintAfter the inspector signs off, access openings are patched, textured and painted to match as part of the normal finish work.

Planned early, the plumbing never holds up the tile setter or the cabinet installer.

Should you replace every pipe or only the remodeled section?

If the house still has galvanized steel throughout, replacing all of it at once is usually the better long-term call. Partial replacement makes sense when most of the home has already been updated and only one branch remains.

The reasoning is simple. New fixtures fed by sixty-year-old steel still have a weak link. Low flow at the shower, rust flakes clogging a new faucet cartridge, and the next leak somewhere you didn’t open up are common outcomes of a half-done job.

That said, budgets are real. A fair middle path is to replace everything reachable through the remodel area and the attic, which in many of these one-story ranch homes covers most of the system, and schedule the last branch for later.

If the project is a bathroom remodel in Arlington or a kitchen update, ask the crew to mark on a simple sketch which lines are new and which remain. Keep it with your house papers.

💡 Good to know: After a repipe, run each faucet for a minute or two and clean the aerators. Loose scale shaken free during the switchover tends to collect there in the first day, and a quick rinse is all it takes.

What homeowners near Pirie Park usually run into

Shutoff valves that don’t shut off. The original gate valves at the main and under the sinks are often seized or only partly close, so the first real job is getting reliable control of the water. Experienced crews plan for that rather than discovering it with a wrench in hand.

Hidden mixed-metal repairs. Over sixty years, several owners and handymen have touched these systems. It’s common to open a wall and find a copper patch, a brass fitting and a length of galvanized within a few feet, each junction a little rusty. Those sections get removed rather than reused.

Plaster and older wallboard. Homes from the 1950s and early 60s around Masonic Home and West Sanford Street sometimes have plaster over gypsum lath rather than modern drywall, and it patches differently and takes more finishing time. A fair estimate accounts for the patching, texture matching and paint, not just the pipe.

Water heaters near the end of their life. Years of rust and scale from galvanized lines settle at the bottom of the tank, and many homeowners find the heater was the next thing due anyway. Decide that before the new lines are tied in, not after.

FAQ

How do I know if my Arlington home has galvanized pipes?

Look at the exposed pipe at the water heater or under a sink. Galvanized steel is dull gray with threaded joints, and a magnet sticks to it. Copper is reddish and smooth, PEX is flexible colored tubing. Brownish morning water and weak pressure at distant fixtures are added clues that old steel is still in service.

Can galvanized pipes be left in place during a remodel?

Yes, and that is the usual approach on slab homes. Rather than cutting concrete to pull old under-floor lines, crews cap them and leave them where they are, then run new PEX or copper through the attic and down inside the walls. The abandoned steel carries no water and causes no harm once isolated.

Does a repipe have to be permitted and inspected?

In general, yes. Replacing supply lines is plumbing work, and in Arlington it is permitted and inspected through the city. Your contractor pulls the permit, schedules the inspection and meets the inspector on site. Requirements differ between cities and change over time, so let the crew confirm what applies to your address.

How long does a whole-house repipe take in an older ranch home?

Most one-story ranch homes around Pirie Park and West Sanford Street in Arlington can be repiped in a few working days when the work is folded into a remodel. Water is typically off for only part of a day during the switchover, and patching and paint follow once the inspector has signed off.

Is PEX or copper better for replacing old steel lines?

Both are proven choices. PEX bends around corners, needs fewer joints and handles freezes well, which is why most North Texas repipes use it. Copper has the longest track record and tolerates heat, but every joint is soldered and some water conditions cause pinholes. Your crew can weigh the two for your home.
