Cobb System Water
The county water system buys finished water from the Cobb County-Marietta Water Authority, which withdraws from Lake Allatoona and the Chattahoochee River, and the county website explains how it provides water to residents. Check your bill and the county’s annual report. The service line past the meter and the plumbing inside are the owner’s.
Homes From the 1980s to the 2000s
Original water heaters, shutoffs and supply stops are often at or past their expected life, and some homes from the late 1970s to the mid-1990s have polybutylene lines. Report defects in newer homes to the builder in writing while the warranty is active.
Historic Downtown and Rail Corridor
Older homes and shops near the tracks have galvanized supply and cast iron drains. Trains and heavy traffic cause steady vibration that can loosen fittings over time.
Red Clay and Hillside Lots
Cobb lots slope and sit on clay that swells and shrinks. Watch for new foundation cracks and damp spots in yards.
Freeze Protection and Shutoff Valves
A winter plan costs little compared with a flooded floor and ruined drywall. Know where the main water shutoff is and test that it turns, since a stuck valve is useless in a flood. A plumber can walk the house and mark every vulnerable spot in one visit.
Why Fixtures Stain or Crust
Soft water leaves little scale but can cause pinhole leaks in older copper lines. A water test shows pH and hardness, which tells you whether scale or corrosion is the larger risk. If the unit is old, water heater repair can tell whether a flush will help.
Slab Leaks
A leak under the floor can run for weeks before anything shows. Check irrigation lines too, since they leak just as quietly. Detection tools locate the line so only a small repair is needed. Emergency plumbing is there when water is flowing.
Drains and Roots
Know where your cleanout is so a plumber can reach the line quickly. A locator marks the spot so any repair stays small. Simple clogs call for drain cleaning; a cracked or collapsed line calls for sewer line repair.

Quick Checks Before You Call a Plumber in Kennesaw
Know the difference between a plunger and a snake. A flange plunger works on toilets and a cup plunger on sinks and tubs; a small hand auger can reach a few feet into the line. If several drains are slow, or a cleanout fills, stop and call a plumber, since forcing more water into a blocked main line only pushes the problem back into the house.
If you have a water softener, check the salt level monthly and listen to make sure it cycles. A bridge of hardened salt in the tank can stop it working even when the tank looks full. Test the water with a hardness strip every few months. If the water feels hard after regeneration, the resin or the valve may need service, and a plumber can test and adjust the unit.
Refill the traps in floor drains and rarely used sinks by pouring a quart of water into them. Dry traps let sewer gas into the house, and a sewage smell that fades after you add water is likely a dry trap rather than a broken line. If the smell returns quickly, a vent problem or a cracked drain may be the cause, and an inspection can find it.
Flush the water heater once a year if it is a tank model. Turn off power or gas, connect a hose to the drain valve and run the water until it clears. On an old tank that has never been flushed, ask a plumber first, since moving old sediment can expose leaks. Regular flushing slows scale buildup and keeps the burner or elements working efficiently for longer.

Frequently Asked Questions — Plumbing in Kennesaw, GA
Who can I call for a leaking water heater in Kennesaw, GA right now?
Turn off power or gas to the heater and close its supply valve, then call the number on this page and enter your ZIP code. Describe the leak and ask for the company name and arrival window. See the emergency plumbing page.
How do I deal with hard water scale in my Kennesaw home?
Soak aerators and showerheads in vinegar, flush the water heater yearly and descale tankless units on schedule. A plumber can advise whether a softener makes sense for your home.
Who supplies water in Kennesaw?
Kennesaw area water comes through Cobb County’s system. Your bill confirms who serves your address.
Is Kennesaw water hard?
Georgia surface water is soft and slightly acidic, so the usual trouble is pinhole leaks in copper rather than heavy scale. A written inspection can show pitting before a wall is damaged.
Do Kennesaw homes from the 1980s have polybutylene pipe?
Homes built from the 1980s into the mid 1990s may still have polybutylene supply lines, which can fail at fittings without warning. A written inspection tells you what is in the walls.
Why does my Kennesaw drain keep clogging?
Georgia red clay holds water, shifts with wet and dry seasons and lets tree roots wrap around drain lines. A camera run shows whether the cause is roots, a belly or a break.
How do I find a hidden leak in a Kennesaw house?
Turn off every tap and read the meter. If it keeps moving, the leak is hidden, and leak detection can find it without opening walls.
