Main shut-off valve

Every homeowner should know where this valve is before they need it, because a burst pipe does not wait. In Marion and Cedar Rapids homes it is typically on the street side of the water meter in the basement. If yours is an old gate valve that has not been turned in decades, test it gently; a valve that will not close is worth replacing before an emergency, not during one.

Why knowing this valve is worth more than any tool you own

A burst supply line can put hundreds of gallons into a house per hour, and everything about the damage bill comes down to how fast the water stops. Insurance adjusters see the same story constantly: the difference between a wet-vac cleanup and a gutted basement was ten minutes of someone hunting for a valve. Every adult in the house should be able to walk to the main shut-off in the dark. In most Marion and Cedar Rapids basements that is at the meter near the front foundation wall — and the moment to confirm yours works is a calm Saturday, not during the flood.

Test it before winter — here is what failure looks like

Once a year, ideally before pipe-freezing season, close the valve fully and reopen it. A handle that will not budge, a stem that weeps water when turned, or a valve that closes but water keeps running are all failures — and an old round-handle gate valve showing any of them should be replaced with a quarter-turn ball valve on your schedule. While you are down there, find the meter and note whether its small dial spins with everything off; movement with all fixtures closed means something is leaking somewhere.
