Fall Plumbing Checklist for Marietta, GA Homeowners

Fall is the best window all year for plumbing maintenance. The weather cooperates, plumbers aren’t buried in winter emergency calls yet, and every small thing you handle now is something that won’t become a crisis during a January cold snap. Cobb County winters are mild, but hard freezes happen most years — and the homes that end up with burst pipes are nearly always the ones where a minor vulnerability went unnoticed in October.

Here’s a practical checklist for Marietta, East Cobb, and Smyrna homeowners, in roughly the order that matters most.

1. Disconnect Hoses and Protect Outdoor Spigots

Start here — it takes five minutes and prevents the most common freeze failure we see. A hose left connected to an outdoor faucet traps water in the spigot and the pipe behind it. During a hard freeze, that water expands and can split the pipe inside your wall. The failure often stays hidden until spring, when you turn the spigot on and water runs into your crawlspace or wall cavity instead.

Disconnect and drain all hoses. Frost-free spigots handle the rest on their own; older standard hose bibs benefit from an insulated cover. Many Marietta, East Cobb, and Smyrna homes from the 1970s and 1980s have standard hose bibs rather than frost-free versions, so it’s worth checking which you have.

2. Get Your Water Heater Serviced Now

Water heaters fail more in winter than any other season, and the reason is straightforward: incoming water is colder, so the unit works harder and longer to deliver the same hot water. That extra demand is what tips an aging unit into failure — usually on the coldest morning, when you least want to be making a rushed decision.

Have the tank flushed to clear the sediment that accumulates in any water heater over a year of use; it restores efficiency and extends the unit’s life. If your heater is 10 or more years old, get it assessed now while you have time to consider your options, including whether a tankless conversion makes sense. Tankless owners should schedule annual descaling, which is manufacturer-required maintenance to keep the warranty valid.

3. Insulate Pipes in Unconditioned Spaces

Crawlspaces, attics, garages, and exterior walls are where freezes actually occur. Foam pipe insulation is cheap and easy to install on accessible runs. Just as important, look for air leaks near exposed plumbing — cold air moving across a pipe freezes it faster than still cold air, so sealing gaps often matters more than the insulation itself.

Many older Marietta and East Cobb homes have crawlspaces with significant exposed plumbing, which is the most common freeze point we get called to in this area.

4. Clear Slow Drains Before the Holidays

Kitchen drains work harder between Thanksgiving and New Year’s than any other stretch of the year — more cooking, more grease, more disposal use, more guests. A drain that’s merely slow in October is very likely to back up completely when you’re hosting.

This matters more in older Cobb County homes. Many houses built before 1990 in Marietta, East Cobb, and Smyrna have cast iron drain lines, and decades of internal corrosion leave the pipe wall rough — grease and debris cling to that surface far more readily than to smooth pipe. If your kitchen drain is already sluggish, have it cleared now, and keep fats, oils, and grease out of it entirely through the holidays.

5. Test Your Sump Pump

If your home has a sump pump, test it before the wet season. Pour a bucket of water into the pit and confirm the pump activates, discharges, and shuts off cleanly. A sump pump that fails during a heavy winter rain means a flooded basement, and the test takes two minutes.

6. Locate and Test Your Main Shutoff Valve

If a pipe bursts, how quickly you can stop the water determines whether you have a repair or a disaster. Make sure everyone in the household knows where the main shutoff is. Test that it actually turns — valves that sit untouched for years frequently seize — and if it doesn’t operate smoothly, have it replaced now. It’s a small job in October and a very large relief in January.

7. Consider a Whole-Home Plumbing Assessment

If your Marietta or East Cobb home dates to the 1970s, 1980s, or 1990s and has never had a comprehensive plumbing assessment, fall is the right time to schedule one. Understanding the condition of your supply lines, cast iron drains, water heater, and shutoff valves means you can plan work on your own timeline rather than reacting to a failure. It’s particularly worthwhile if you’ve dealt with a pinhole leak, a recurring drain backup, or an unexplained water bill.

Frequently Asked Questions

Do I really need to worry about frozen pipes in Cobb County?

Yes. Cobb County winters are mild on the whole, but we get hard freezes most years, and that’s all it takes to burst an unprotected pipe. What fails here are the exposed pipes — outdoor spigots with hoses still attached, plumbing running through unheated crawlspaces and garages, and lines along exterior walls. Because our climate is mild, many Marietta and East Cobb homes were built without the freeze protection that’s standard in colder regions, which is why a single hard freeze produces so many burst-pipe calls locally. Prevention is simple and inexpensive: disconnect garden hoses, insulate pipes in unconditioned spaces, and seal air leaks near exposed plumbing.

Why do water heaters fail more often in the winter?

Because they work substantially harder. Incoming municipal water is colder in winter, so the unit has to raise the temperature further and run longer to deliver the same amount of hot water. That sustained extra demand is what pushes an aging or sediment-heavy water heater into failure — which is why plumbers see a surge in replacements during the first real cold snap. Servicing in the fall addresses both parts of the problem: flushing removes the sediment that accumulates in any tank over a year and restores efficiency, and an inspection tells you honestly whether the unit will make it through another winter. If it’s 10 or more years old, replacing it proactively in fall is far better than doing it in an emergency in January.

My kitchen drain is a little slow. Can it wait until after the holidays?

We’d recommend handling it now. Kitchen drains take more load between Thanksgiving and New Year’s than any other period of the year, and a drain that’s already slow in the fall very often fails completely when you’re hosting. This is especially true in older Marietta and East Cobb homes with cast iron drain lines, where decades of internal corrosion have roughened the pipe wall so grease and debris catch and accumulate more easily. Clearing it in October is a scheduled appointment; clearing it on Thanksgiving Day is an emergency call. Through the holidays, keep fats, oils, and grease out of the drain — pour cooled grease into a can and discard it rather than rinsing it down.

What’s the most important fall plumbing task if I only do one thing?

Disconnect your garden hoses. It takes five minutes, costs nothing, and prevents the most common cold-weather plumbing failure we see. A hose left attached traps water in the spigot and the pipe behind it; when that water freezes and expands, it can split the pipe inside your wall — and because the break is concealed, homeowners often don’t discover it until spring, when turning on the spigot sends water into a crawlspace or wall cavity. If you have time for a second task, locate your main water shutoff valve and confirm it turns freely, so you can stop the water fast if anything does fail.
