1
Multiple drains backing up at the same time
🟢 beginner 🔥 High Impact
When two or more drains — a toilet and a shower, a kitchen sink and a floor drain — back up simultaneously during or after heavy rain, the problem is almost certainly in your main sewer line, not an individual fixture. Stormwater can overwhelm aging sewer laterals, and roots or cracks that were borderline before the rain become full blockages under pressure. A single clogged drain is an inconvenience. Multiple drains backing up is a main-line emergency that gets worse every hour.
Pro tip: Flush a toilet on the lowest level of your home. If water comes up in a nearby shower or floor drain, your main line is compromised.
2
Sewage smell coming from floor drains or cleanouts
🟢 beginner 🔥 High Impact
A sewer-gas smell after heavy rain means water that normally sits in your drain traps has been displaced by backpressure from the municipal system or your lateral. Dry traps let sewer gas — including methane and hydrogen sulfide — into your living space. If the smell persists after you pour a gallon of water into each floor drain to refill the traps, there is likely a break or backflow issue in your sewer line that requires professional diagnosis.
Pro tip: Hydrogen sulfide is toxic at high concentrations. If the smell is overwhelming or anyone feels dizzy, leave the house and call from outside.
3
Water pooling around your foundation that was not there before
🟢 beginner 🔥 High Impact
New puddles against your foundation wall after rain — especially if your yard grading has not changed — can indicate a broken underground water or sewer line. A cracked lateral leaks water into the surrounding soil, and rain amplifies the volume. Left alone, this saturates the soil around your foundation and can cause settling, cracking, or basement flooding within weeks.
Pro tip: Check whether the pooling water has an odor. Clean rainwater pooling is a grading issue. Foul-smelling pooling is a sewer-line break.
4
Gurgling sounds in pipes when you are not using water
🟢 beginner 💪 Medium Impact
Gurgling from a toilet, sink, or shower drain when no water is running means air is being pulled through your plumbing system by negative pressure — usually from a blocked or flooded vent stack or a main-line obstruction. After heavy rain, debris and standing water can block vent openings on your roof. The gurgling itself is harmless, but it signals a venting or drainage failure that will escalate to backups if not addressed.
Pro tip: If gurgling starts only during rain and stops after, your vent stack may be partially blocked by leaf debris. A plumber can clear it in under an hour.
5
Your sump pump is running constantly but water level is not dropping
🟡 intermediate 🔥 High Impact
A sump pump that runs nonstop without lowering the pit water level means water is entering faster than the pump can discharge it — or the discharge line is blocked or frozen. After heavy rain this can mean groundwater pressure has overwhelmed your drainage system, or a broken underground pipe is feeding water directly into the pit. Running a pump to failure burns out the motor, typically $400–$800 to replace, and leaves your basement unprotected.
Pro tip: Check the discharge pipe outside. If water is not flowing out the end, the line is blocked or disconnected underground — a plumber can diagnose this with a camera.
6
Brown or discolored water coming from faucets after the storm
🟢 beginner 💪 Medium Impact
Discolored water after heavy rain can mean storm runoff has infiltrated your well system, or municipal main breaks caused sediment disturbance. In homes with private wells, brown water after storms is a contamination risk that requires testing before drinking. Even on city water, sudden discoloration can indicate a water-main break near your property that has introduced soil into the line.
Pro tip: Run cold water from the faucet closest to your water meter for 5 minutes. If it clears, the issue was sediment in your service line. If not, call your water utility and a plumber.
7
Wet spots or soft ground over your sewer lateral path
🟡 intermediate 🔥 High Impact
If you know roughly where your sewer lateral runs through the yard — usually a straight line from your house to the street — and you find new wet spots or unusually soft, spongy ground along that path after rain, the pipe may be cracked or collapsed. Rain infiltrates the break, saturates the trench backfill, and creates surface-level soft spots. Walking on it can cause further collapse.
Pro tip: Avoid driving, parking, or placing heavy objects over the sewer lateral path. Additional weight on a compromised pipe accelerates collapse.
8
Basement walls are weeping water in new locations
🟡 intermediate 🔥 High Impact
Existing weep points in a basement often activate during heavy rain — that is normal hydrostatic pressure. But new weep locations, especially along the floor-wall joint, can indicate that a broken water or sewer line has changed the underground water flow pattern near your foundation. New water entry points after rain suggest a plumbing or drainage failure, not just seasonal groundwater.
Pro tip: Mark new weep locations with painter's tape and date them. This documentation helps the plumber distinguish structural seepage from pipe-related infiltration.
9
Your water meter shows usage when everything is off
🟢 beginner 🔥 High Impact
Turn off every water-using fixture and appliance in your home, then check your water meter. If the flow indicator is still spinning, you have an active leak somewhere in your supply line. Heavy rain can shift soil and crack underground supply pipes, especially older copper or galvanized lines. An underground supply leak after a storm can waste hundreds of gallons per day and erode the soil supporting your foundation.
Pro tip: Record the meter reading, wait 30 minutes with all water off, then read again. Even a slow supply-line leak will show movement over 30 minutes.

Bonus Tip
Photograph everything before the plumber arrives
Take photos and video of any backups, wet spots, discolored water, and soft ground before anyone starts working. Insurance claims for storm-related plumbing damage require proof of the initial condition. Once a plumber starts digging or clearing, the original evidence is gone.
