Plumbing in Louisville lives in humidity, hard rain, and older pipe, with a freeze only on the nights that earn it. Galvanized in the old city narrows and pinholes. Cast iron hubs rust. Outside-wall sinks and charged hose bibs split when a cold snap hits air that was damp yesterday. Clay and valley rain push water at basements, so floor drains and sump pumps have to answer. Find the main shutoff before the valve proves it is stuck. A drip becomes a plaster stain quickly here.
Water rising in a floor drain during a storm is not a supply leak overhead. Say which way it moves. A cable can clear a clog and leave a broken or root-bound line, so say opening or repair. Crawl-space piping sweats all summer and hides leaks above a dirt floor. Sump discharge dumped beside the foundation walks back inside. Low streets can load a line even when your fixtures are fine. Show where the water actually appears.
Water heaters in basements and closets quit or weep down the shell in damp air. Some newer houses put them in garages. Gas versus electric changes the vent. The pan needs a path that is not the floor or the crawl. A flue into an old chimney should be part of the description on brick houses. Rusty hot water is a warning in this climate, not a quirk. Say the fuel and whether you are without hot water or mopping.
A weeping stop under a sink becomes a ceiling stain in a shotgun before you notice the cabinet. If a claim may follow, shut the water and photograph before plaster is opened. A rocking toilet points at the flange. Spraying galvanized should be shut off, not forced. Most of these houses are on city water, so say if yours is not. A slow drip in river air will not stay polite through a humid week.
Say burst, backup, clog, or water heater, and say if the main will turn. Mention the hose bib and whether the basement or the crawl is already wet. Call the number on this page.
