The City of Maryville's flooding page says flooding is not covered by a standard homeowner's policy, and it offers a way to look up a property's flood zone. That is worth doing for any house near a creek or low ground.

If water has gotten in, a plumbing leak and a flood are different claims. Ask your insurer which one applies. See getting water out and drying a house for how removal and drying work.

Hot Water Trouble in Older and Newer Homes Alike
We did not find a source for the age of homes near the park, so this page makes no claim about it. The checks for a failing heater are the same either way.
| What you see | First check | Page |
|---|---|---|
| No hot water | Pilot, breaker or thermostat | checking a heater with no hot water |
| Water at the base of the tank | Fittings first, then the tank | finding a heater leak |
| A heater past its prime | Age and repair history | what replacing a heater involves |
Maryville's water is moderately hard by the City's 2022 figure of 60.1 milligrams per liter, so ask whether the tank was flushed.
Fixtures, Faucets and Under-Sink Leaks
- A drip from a faucet is usually a worn cartridge or washer.
