Plumbing in Indianapolis fails on the freeze that follows rain. Outside-wall sinks seize and then leak on the thaw. Hose bibs split if they were left charged. Older galvanized pinholes, and cast iron hubs rust. Clay pushes storm water at the basement so the floor drain or the sump has to answer. Find the main shutoff before a night when the valve is stuck.
Rain coming up a floor drain is not a ceiling supply leak. Say which way the water moves. A cable can clear a clog and still leave a broken line, so say opening or repair. A basement bath changes the drain height. If the sump dumps beside the wall, that water comes back. Show where the discharge pipe ends.
Basement heaters fail before dawn or weep down the shell when they are finished. Garage heaters in newer houses take a colder snap. Gas versus electric changes venting. The pan needs a path that is not the floor. A flue into an old chimney should be part of that description. Say the fuel, and say if you have no hot water or a leak you can see.
A weeping stop under a sink becomes a ceiling stain downstairs. Shut the water and take photos before you open plaster if a claim may follow. A rocking toilet points at the flange. Spraying galvanized should be shut off, not forced. A drip in a freeze-then-thaw winter will not stay a drip. Most of these houses are on city water, so say so if yours is not.
Say burst, backup, clog, or water heater, and say if the main will turn. Mention the hose bib and whether the basement is rising. Say if the floor drain gurgles when rain hits. Old valves seize, so do not wait to learn that during the leak. Call the number on this page.
