A plumbing inspection in Marietta is a plumber's review of the water heater, supply and drain pipe, valves and fixtures, with optional video of the sewer line. It is a smart step before buying a home near the Square or planning a remodel. Call the number on this page to be connected with a local plumber in Marietta.

Marietta's water and housing
Marietta Water, part of the city's Power & Water utility, provides both water and sewer inside the city. It buys treated water from the Cobb County-Marietta Water Authority, which draws from the Chattahoochee River and Lake Allatoona. Marietta-addressed homes outside city limits are often on Cobb County Water System instead, so check the bill. Marietta Water's report says it handles lead service line removal, while homeowners are responsible for any lead materials in their own plumbing.
Housing is mixed. The median home was built in 1987 and about 33.2% predate 1980, with older pipe more likely around Marietta Square and the streets near Cobb Parkway. Marietta Water runs a cross-connection program: testable backflow devices must be tested every year by a certified tester, with results sent to the utility. City of Marietta Building Inspections issues plumbing permits for changes to existing buildings, and the plumber who does the work normally files it. Book early in any due-diligence period, and add a sewer camera run for older lots with big trees.
Picking the scope
| Option | What it covers | Best fit |
|---|---|---|
| Walk-through only | Exposed supply and drain pipe, fixtures, valves, water heater, pressure | Newer houses, quick pre-offer look |
| Walk-through plus camera | All of the above and video of the sewer lateral | Older homes, big trees, past backups |
| Single-issue visit | One concern such as a leak, the water heater or pressure | Owners chasing one problem |
| Pre-listing review | Whole-house check with a written list of findings | Sellers who want no surprises |
Times a full check pays off
- You are adding a bathroom and need to know if the existing lines can handle it
- Drains in more than one room run slowly or gurgle
- The meter moves when every fixture is off
- Pipes hammer when a valve shuts off
- You have a contract on a house and a short due-diligence window
- You want a repair list in hand before listing the house
When to book it
The best time is early: early in a contract period, early in remodel planning, or soon after you first notice a symptom. Waiting until a deadline is near leaves little time to act on what the plumber finds.
