Snowbird Plumbing Checklist: Returning to Your South Florida Home

The most common issues returning snowbirds find in South Florida homes are: dried-out toilet wax seals that allow sewer gas indoors (from 3–6 months without flushing), water heater sediment and anode rod deterioration accelerated by sitting stagnant, irrigation system failures from summer storm debris or freeze damage, and slow drains from drain trap evaporation. Homes in coastal areas also often show accelerated corrosion on flexible supply lines and fixture fittings from salt air during absence.

You can restore water yourself if the home is less than 2 years old and was properly prepared before you left (water shut off, water heater turned off, irrigation winterized). For homes that were not properly shut down, or that are more than 10 years old, or where you notice any signs of moisture, staining, or odor on arrival, have a licensed plumber inspect before restoring full service. A pre-occupancy plumbing inspection costs $150–$300 and can prevent a $5,000–$20,000+ water damage event from an undetected leak.

Run every hot and cold faucet for 2–3 minutes to flush stagnant water from supply lines. Flush every toilet 2–3 times. Run the dishwasher on a short cycle. Run the washing machine on a rinse cycle. This clears mineral deposits, bacteria that can accumulate in stagnant water, and any debris that entered during vacant periods. For homes with a whole-house water filter, replace the filter cartridge before running water through the system.

If the water heater was properly shut off before you left: restore power or gas, allow 45–60 minutes for a tank unit to reheat, then check for any leaks at the T&P valve or drain valve. If the water heater was left on during your absence: check for sediment (cloudy or discolored hot water), listen for rumbling or popping sounds indicating heavy scale buildup, and schedule a professional flush, South Florida's hard water (15–25 grains per gallon per SFWMD) causes sediment to accumulate at 2–3x the national average rate.

Turn the irrigation controller to manual mode and run each zone for 2–3 minutes. Walk each zone and look for: broken or tilted heads, heads stuck in the up position (won't retract), pooling water suggesting a broken lateral line, and heads spraying in the wrong direction. South Florida's summer storm season commonly breaks above-ground rotors and shifts popup heads. Also check that the backflow preventer on your irrigation system is intact, annual backflow testing is required by Florida utilities.

Not automatically, but inspect for signs of failure first. A dried wax seal may allow sewer gas (hydrogen sulfide) into the home, detectable as a rotten egg smell near the toilet base. If you notice any odor, or if the toilet rocks slightly when you sit on it, the wax seal should be replaced. Wax seal replacement costs $150–$250 per toilet including labor. Some snowbirds cover toilet bowls with plastic wrap before leaving to slow evaporation, this helps but doesn't eliminate the risk entirely in South Florida's heat.
