Plumbing Problems Atlanta Homeowners Face During Heavy Summer Storms
Summer storms in the Atlanta area can bring intense rainfall, strong winds, lightning, and localized flooding in a short amount of time. While most homeowners think first about roof leaks, fallen branches, and power outages, heavy rain can also put significant pressure on a home’s plumbing and sewer system.
If your drains begin gurgling during a storm, a basement floor drain backs up, or water suddenly appears in an unexpected area, the timing may not be a coincidence. Rainwater can enter damaged sewer lines, saturate the ground around underground pipes, expose hidden leaks, and overwhelm drainage systems that were already partially clogged.
Hers & His Plumbing provides professional plumbing services in Atlanta and surrounding communities for homeowners dealing with drain backups, sewer problems, hidden leaks, and other storm-related plumbing concerns. Understanding the most common warning signs can help you act before a manageable issue turns into significant water damage.
Why Heavy Rain Can Affect Your Home’s Plumbing
Your household plumbing system and the municipal stormwater system are designed to perform different jobs. The plumbing system carries wastewater from toilets, sinks, showers, washing machines, and other fixtures toward the sanitary sewer. Storm drains are intended to carry rainwater away from roads, yards, and other outdoor surfaces.
However, heavy rain can still affect sanitary sewer systems. Groundwater and stormwater may enter through cracked pipes, deteriorated joints, damaged manholes, or improper connections. This is known as infiltration and inflow.
When too much water enters the sewer network at once, the added volume can contribute to slow drainage, backups, or sanitary sewer overflows. The U.S. Environmental Protection Agency explains that sanitary sewer overflows can back up into homes, cause property damage, and create public-health concerns.
Problems are more likely to become noticeable during storms when a home already has a partial clog, damaged sewer line, root intrusion, poor grading, or another weakness in the system.
1. Sewer Water Backs Up Through a Floor Drain, Shower, or Toilet
One of the most urgent plumbing problems during heavy rain is wastewater backing up into the home. It may first appear through a low-level fixture such as a basement or utility-room floor drain, downstairs shower, bathtub, or toilet.
A sewer backup may occur when a blockage prevents wastewater from leaving the home or when rainwater enters a damaged sewer line and overwhelms its available capacity. If the main line is already narrowed by grease, debris, tree roots, or deterioration, a major storm may be enough to trigger a backup.
Warning signs can begin before sewage becomes visible. You may hear gurgling from toilets, notice several drains slowing at the same time, or see water rise in a shower when another fixture is used.
If wastewater begins backing up, stop using sinks, toilets, washing machines, and dishwashers. Continuing to send water into the plumbing system can increase the amount that enters the home. Keep children and pets away from the affected area, since sewage can contain harmful contaminants.
Hers & His Plumbing offers professional sewer repair services to diagnose clogged, cracked, leaking, or damaged sewer lines. Depending on the condition of the line, the solution may involve cleaning, targeted repair, or sewer line replacement.
2. Drains Become Slow or Start Gurgling During Rainstorms
A single slow sink is often caused by a localized clog. When several fixtures begin draining slowly at the same time—especially during or immediately after heavy rain—the problem may involve the main sewer line.
Gurgling occurs when air becomes trapped or displaced inside the drainage system. You might hear bubbling from a toilet when the washing machine drains, notice a shower drain making noise after a toilet is flushed, or see the water level in a toilet move without anyone using it.
These symptoms can indicate that wastewater is struggling to move through the line. Heavy rain may intensify an existing problem by allowing groundwater to enter through cracks or weakened pipe connections.
Do not repeatedly use chemical drain cleaners to address storm-related drainage problems. They may not reach a blockage in the main sewer line and can make professional service more hazardous. A plumber can determine whether the issue requires professional drain cleaning, hydro jetting, a sewer camera inspection, or a structural repair.
Addressing the warning signs early is usually easier than waiting for wastewater to back up into the home.
3. Tree Roots Enter Cracked Sewer Pipes
Large, mature trees are common throughout many Atlanta neighborhoods. Although they provide shade and curb appeal, their roots naturally seek moisture and can enter sewer pipes through small cracks, loose joints, or deteriorated connections.
Once roots find an opening, they can continue growing inside the line. Waste and toilet paper begin catching on the root mass, gradually restricting the pipe. The sewer may continue functioning during normal weather but struggle during a heavy rain event when the surrounding soil becomes saturated and more water enters the system.
Recurring clogs, frequent backups, multiple slow drains, and lush or unusually wet areas in the yard can all point to sewer line trouble. A camera inspection allows a plumber to see whether roots, corrosion, a collapsed section, or another obstruction is responsible.
Simply clearing the roots may temporarily restore flow, but the damaged area that allowed them to enter may still require repair. Hers & His Plumbing’s sewer services include camera-based diagnostics and both traditional and less-invasive repair options.
4. Hidden Pipe Leaks Become More Noticeable
Heavy rain does not necessarily cause every plumbing leak, but it can make an existing underground or concealed problem easier to detect.
Saturated soil can shift around water and sewer lines. Weak connections, corroded pipes, and previously damaged sections may begin leaking more noticeably as the surrounding conditions change. Indoors, homeowners may discover damp drywall, musty odors, peeling paint, warped flooring, or unexplained moisture near plumbing fixtures.
Outdoors, signs of an underground leak can be harder to distinguish from normal stormwater. Pay attention to areas that remain soggy long after the rest of the yard has dried, unexpected erosion, depressions in the soil, or patches of vegetation that appear unusually green.
Professional leak detection services can help pinpoint hidden plumbing leaks without unnecessary damage to the surrounding property. This is especially useful when the source is beneath concrete, underground, or behind finished surfaces.
A leak should be investigated promptly even if it appears only during storms. Repeated moisture can damage building materials, contribute to mold growth, and worsen the condition of the pipe over time.
5. Water Enters Around a Basement or Low-Level Drain
Homes with basements, lower levels, or below-grade plumbing fixtures may be particularly vulnerable when the ground becomes saturated. Water may enter through foundation cracks, but it can also appear around floor drains or other plumbing penetrations.
The source matters because foundation seepage and a sewer backup require different solutions. Clear rainwater near a wall may suggest groundwater intrusion, while foul-smelling or discolored water emerging from a drain is more consistent with a plumbing or sewer problem.
Avoid assuming that all basement water is coming through the foundation. If water appears near a floor drain, toilet, utility sink, or washing-machine connection, a plumber should evaluate the drainage system.
Installing or maintaining appropriate backwater protection may help certain homes, but the correct solution depends on the plumbing layout and local requirements. A professional inspection can determine whether a clog, sewer defect, drainage issue, or another source is responsible.
6. Outdoor Drains and Yard Drainage Systems Overflow
Outdoor drains, channel drains, and catch basins help move rainwater away from patios, driveways, foundations, and low areas of the yard. When they become blocked with leaves, soil, mulch, or other debris, water may pool near the home instead.
Standing water around the foundation can increase the likelihood of basement moisture, erosion, and soil movement. It may also conceal underground plumbing problems.
Before storm season, homeowners should remove visible debris from accessible outdoor drains and make sure water can flow away from the structure. However, recurring backups may indicate a blockage farther inside the line, improper grading, a damaged drain, or insufficient capacity.
Outdoor drainage lines should not be connected improperly to the sanitary sewer. Directing stormwater into the sanitary system can increase the risk of overload and may violate local regulations.
A plumber can determine whether an affected line is part of the household plumbing, a sewer lateral, or a separate stormwater drainage system.
7. A Partially Clogged Sewer Line Fails Under Increased Demand
Summer storms often occur at the same time that a home’s plumbing is seeing heavier use. Children may be home from school, guests may be visiting, and washing machines, showers, toilets, and kitchen fixtures may be used more frequently.
A sewer line that is already partially restricted may handle ordinary use without obvious symptoms. Add saturated soil, stormwater infiltration, and increased household demand, and the problem may suddenly become apparent.
This is one reason storm-related backups sometimes seem to happen without warning. The storm may not have created the original blockage—it may simply have exposed it.
Preventive cleaning can remove grease, sludge, and certain obstructions before they completely block the line. For stubborn buildup in a structurally sound sewer pipe, hydro jetting uses a high-pressure stream of water to clean the interior of the pipe.
The appropriate method depends on the age and condition of the plumbing. Older or weakened lines should be inspected before high-pressure cleaning is used.
8. Toilets Bubble or Lose Water From the Bowl
A toilet that bubbles during a rainstorm is often reacting to air movement in the drain or sewer line. You may see bubbles rise through the bowl, hear gurgling, or notice the water level change unexpectedly.
These symptoms can result from a developing main-line clog, a blocked plumbing vent, or pressure changes in an overloaded drainage system. If the toilet bubbles when another fixture drains, the issue is more likely to extend beyond the toilet itself.
Do not continue flushing repeatedly to see whether the problem resolves. If the main sewer line is blocked, additional flushing may cause wastewater to emerge through a lower fixture.
A plumber can evaluate the toilet, nearby drains, vents, and sewer line to identify the source. When several fixtures are involved, the problem is unlikely to be solved by replacing a component inside the toilet tank.
9. Sewer Odors Enter the Home
Sewer odors during or after a storm may indicate that sewer gases are entering through a dry drain trap, damaged pipe, loose toilet seal, or drainage problem.
Every properly functioning drain should have a water-filled trap that blocks sewer gases. In a rarely used sink, shower, or floor drain, the water inside the trap may evaporate. Pouring water into an unused drain may restore the seal.
Persistent odors, however, should not be dismissed. A cracked sewer pipe, failed wax ring beneath a toilet, blocked vent, or sewer backup can also allow unpleasant and potentially hazardous gases into the home.
Pay attention to where and when the odor appears. A smell that intensifies during heavy rain may suggest a pressure or drainage issue within the sewer system.
10. Storms Expose Aging or Damaged Sewer Lines
Older sewer lines may be made from materials that become brittle, corroded, displaced, or vulnerable to root intrusion over time. Soil movement and repeated saturation can place additional stress on already compromised pipes.
A damaged line may develop low spots where waste collects, separated joints that allow groundwater to enter, or cracks that permit sewage to escape into the soil. In more serious cases, part of the pipe may collapse.
Symptoms can include recurring drain clogs, sewage odors, backups during rain, wet areas in the yard, or repeated need for drain clearing.
A sewer camera inspection is one of the most effective ways to understand what is happening inside the line. Rather than guessing based solely on symptoms, the plumber can locate the obstruction or damaged section and recommend a repair based on its condition.
What Should You Do During a Storm-Related Plumbing Backup?
If sewage or drain water begins entering your home, stop using all plumbing fixtures. Do not flush toilets, take showers, run the dishwasher, or use the washing machine until the cause has been identified.
Keep people and pets away from contaminated water. Avoid touching electrical equipment or entering standing water near outlets, appliances, or electrical panels.
Do not attempt to open a sewer cleanout unless you know how to do so safely. Wastewater may be under pressure and could spill onto the property.

How Atlanta Homeowners Can Prepare Before the Next Heavy Storm
You cannot control how much rain falls, but you can reduce the chance that an existing plumbing issue catches you by surprise.
Pay attention to drains that are gradually slowing, toilets that gurgle, recurring clogs, and sewer odors. These symptoms should be addressed before severe weather arrives. Keep accessible outdoor drains clear of leaves and debris, and avoid pouring grease or flushing wipes and other non-biodegradable products.
Homes with older sewer lines, large trees, or a history of backups may benefit from a camera inspection and preventive cleaning. Routine maintenance can reveal root intrusion, buildup, damaged connections, and other concerns before a storm places additional strain on the system.
It is also helpful to know the location of your home’s main water shutoff. Although shutting off the water will not stop a municipal sewer backup, it can limit damage if a supply line breaks during severe weather.
