If you need a plumber in McDonough, GA, you are in the Henry County seat, where the Henry County Water Authority supplies water from five drinking water reservoirs including Tussahaw, the Towaliga reservoirs, Long Branch and Gardner. Here is what we see most often, and what to do first.
McDonough Plumbing Problems and First Steps
| What You Notice | Common Cause Here | What to Do First |
|---|---|---|
| Dripping faucet | A worn cartridge or seat | Close the stop valve and book a repair |
| Sewer smell outdoors | A cracked lateral or a loose cleanout cap | Check the cap and book a camera check (Sewer Line Repair) |
| Rust-colored hot water only | A corroding tank or anode rod | Flush the tank and book an inspection (Water Heater Repair) |
| Water coming up through the floor | A pressurized leak under the slab | Shut off the main and call right away (Emergency Plumbing) |
| Floor drain backing up | Debris or a clogged lateral | Stop using water and call |
| Stuck shutoff valve | Corrosion from humid air | Test valves yearly and replace stuck ones |
Five Reservoirs
The authority’s 2026 report lists Tussahaw, Upper Towaliga, Lower Towaliga, Long Branch and Gardner reservoirs as the supply, with treatment plants at Towaliga and Tussahaw. Check the authority’s report for current results. Your side starts at the meter and runs through the whole house.
Subdivisions From the 1990s to the 2010s
McDonough grew quickly. Original water heaters, shutoffs and supply stops are reaching the end of their life, and newer homes can still show early defects. Report defects to the builder in writing while the warranty is active.
Square Homes and Older Lots
Homes near the Square date to the early and middle twentieth century and often have galvanized supply, cast iron drains and clay laterals. A written inspection before you buy or renovate shows what is left of the original plumbing.
Red Clay and Storm Runoff
Heavy rain moves fast across clay yards. Keep downspouts clear of the foundation and have a plumber check yard drains and the sewer cleanout before the wet season.
Preparing Plumbing for Winter Weather
A burst pipe in a cold snap can release hundreds of gallons before anyone notices. Know where the main water shutoff is and test that it turns, since a stuck valve is useless in a flood. Photograph the shutoffs and keep the photo with your insurance records.
Corrosive Water and Old Copper
Much of Georgia has soft, slightly acidic water that can slowly attack copper from the inside. Flush tank heaters yearly and check the anode rod, since soft water uses it up faster. Water heater repair is available if the tank is already failing.
Slab and Wall Leaks
If the meter keeps turning with every fixture off, a line may be leaking. Check irrigation lines too, since they leak just as quietly. Pinpointing the leak first avoids guesswork and extra demolition. Emergency plumbing help is available.
Sewer Lines and Tree Roots
One slow drain is usually a local clog, but several backing up together point to the main line. A locator marks the spot so any repair stays small. Drain cleaning covers most blockages, while sewer line repair is for confirmed damage.

Quick Checks Before You Call a Plumber in McDonough
Cover or drain outdoor spigots before cold weather, and disconnect hoses so water does not freeze inside the bib. Frost-proof bibs help, but only if the hose is removed. A bib that freezes can split inside the wall and leak only after the thaw. If you see a drip from a bib after a cold night, shut off the supply to it and call for a repair before the wall is damaged.
Before a long trip, turn off the main, open a faucet at the lowest point to drain the lines and set the water heater to vacation or pilot. Ask a neighbor to check the home, and tell them where the shutoff is. A burst supply line in an empty house can run for days, which is why many McDonough insurers recommend shutting off water when you leave for more than a few days.
Keep a short list taped inside a cabinet: the heater model and age, the main shutoff location, the water provider’s phone number, any softener model and the date of the last drain cleaning. During an emergency in McDonough, a clear list saves minutes and calms everyone down. Update it when equipment is replaced, and snap a photo of it for your phone.
Listen for noises. Banging usually points to water hammer from high pressure or loose pipes, whistling to a partly closed valve or a worn washer, hissing to a leak under pressure and gurgling to a vent or drain restriction. Note when the sound happens and which fixture triggers it. That description helps a plumber diagnose the problem faster than a general statement that the house makes noises.

Frequently Asked Questions — Plumbing in McDonough, GA
How do I get urgent plumbing help in McDonough, GA without waiting for business hours?
Dispatch is open at all hours. Call, enter your ZIP code, stay on the line and describe the problem. Ask for the company name and arrival window before agreeing. The emergency plumbing page has a checklist for the wait.
Why is my McDonough, GA water bill so high?
Common causes are a running toilet, an irrigation fault or a hidden leak. Shut off every tap, read the meter, wait an hour and read it again. If it moved, there is a leak, and a plumber can locate it. If it did not move, ask the city to check the meter reading.
Who supplies water in McDonough?
Henry County Water Authority serves McDonough from reservoirs and purchased supply. Your bill confirms your provider.
Is McDonough 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 roots and clay cause sewer backups in McDonough?
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.
Are septic systems common near McDonough?
Check your water bill to confirm whether you are on public sewer or a septic tank. Septic edges are common on the outer parts of the metro.
How do I protect McDonough pipes in a cold snap?
Georgia freezes are short but sharp. Wrap exposed lines, open cabinet doors on cold nights and know where the main shutoff is before an ice storm.
