Marietta has a broad mix of housing, and repiping comes up most in the homes from before the 1990s where galvanized, early copper or polybutylene lines are wearing out. A plumber replaces supply pipe on the house side of the meter, all at once or in sections. Call the number on this page to be connected with a local plumber in Marietta.

Why repiping comes up in Marietta
About a third of Marietta's housing, 33.2%, was built before 1980, and the median home dates to 1987 under Census survey data. The streets around Marietta Square and the historic core hold the oldest houses, where galvanized steel or early copper can still be in the walls. Subdivisions from the 1980s are more likely to have polybutylene or aging copper.
Marietta Water distributes treated water it buys from the Cobb County-Marietta Water Authority, drawn from the Chattahoochee River and Lake Allatoona and disinfected with chlorine. Marietta-addressed homes outside city limits may be on Cobb County Water System instead, so check your bill. Marietta Water's report says it handles lead service line removal, while lead materials in a home's own plumbing are the owner's to deal with. Permits inside the city come from Marietta Building Inspections.
Common replacement materials
| Material | Strengths | Things to weigh |
|---|---|---|
| PEX | Flexible, fewer fittings, snakes through walls with small openings | Must be kept out of direct sunlight; uses crimp or expansion fittings |
| Copper | Long track record, rigid and neat for exposed runs | More labor to solder; price of the metal varies |
| CPVC | Rigid plastic, common in homes from recent decades | Can turn brittle with age and heat; glued joints |
When repairs stop keeping up
- Gray plastic supply pipe, often stamped PB2110, feeds the water heater or the sinks
- Pressure is weak at several fixtures at the same time, not just one faucet
- The first glass of water in the morning has a metallic taste
- PB-stamped gray plastic shows up under a sink or near the heater
- Exposed pipe in the crawl space looks scaly, pitted or patched
- Wet spots in the yard between the meter and the house
- Green or chalky white crust is building up on copper joints and valves
- Repair clamps and patch couplings are already scattered along the exposed lines
Timing and seasonal notes
There's no single right season, but planning helps. A repipe done before winter lets the plumber reroute lines out of cold exterior walls. Avoid scheduling around holidays or houseguests, because the water will be off for parts of several days. If money is tight, ask about doing the worst branch now and the rest later.
Pipe that is already failing tends to pick the worst moment, often a hard freeze or a holiday weekend with a full house. Scheduling a repipe on your own terms, in mild weather, avoids that. Ask the plumber how many days the water will be off during working hours and whether any upstairs bath can stay usable.
