Cost GuideUpdated July 4, 2026
Water emergencies hit fast and can cause expensive damage in Hickory Hills homes, especially if you don't act quickly. Pipes in our area are often decades old and sometimes made from galvanized steel or cast iron, both of which can corrode or fail with age. Whether it's a burst pipe from a winter freeze or a sudden leak behind a wall, knowing how and where to shut off your water can save thousands of dollars in damage to floors, drywall, and belongings. Every minute counts, especially in homes built during the mid-20th century, as many are in Hickory Hills.
Why Fast Shutoff Matters in Hickory Hills Homes
Clay-rich soils and flat terrain in this area make basements vulnerable to flooding. If a pipe lets go or a fixture connection fails, water quickly finds its way into low spots. Our harsh winters mean pipes can freeze and burst. Corroded fittings in older plumbing systems also give out with little warning. Acting quickly by shutting off the water supply limits the spread of water and keeps damage contained, that's especially important in homes with finished basements or vintage wood flooring.
Finding Your Main Shutoff Valve
Most single-family homes around Hickory Hills have a main water shutoff valve inside, often near where the water line enters from the street. For many homes built between the 1950s and 1970s, that's usually in the basement, crawlspace, or a mechanical room near the front foundation wall. You'll typically see a round wheel (gate valve) or a lever (ball valve) on a one-inch copper or old galvanized pipe. Turning the wheel clockwise or the lever perpendicular to the pipe stops all water from entering the house.
If you're unsure which valve is the main, trace the largest pipe as it enters the home. It should run directly to your water meter. Some homes have an additional shutoff between the meter and the street; this exterior valve usually requires a special key and is for utility use, not homeowners.
How to Shut Off Water in a Plumbing Emergency
- Stay calm and locate the main shutoff valve. It's usually in the basement near the front wall, within a few feet of the water meter.
- Turn the valve clockwise (for a gate valve) or a quarter turn so the lever is perpendicular (for a ball valve) to close it fully.
- Open a faucet on the lowest level of your home, often a basement laundry sink, to drain residual water and relieve pressure.
- If you're shutting off the water due to a leak, avoid using any other fixtures until you've confirmed the source is under control.
- If the valve is stuck, corroded, or leaking, call a pro for help. For stubborn valves, we handle pipe repair and repiping to ensure your shutoff is reliable next time.
If the emergency is localized, like a leaking toilet or under-sink supply line, you may have an isolation valve (small oval or lever handle) nearby. These are found just below sinks, behind toilets, and at the top of water heaters. Turning these off can temporarily stop the leak while leaving the rest of your home supplied.
What to Do After the Water is Off
Once you've closed the valve and the flow has stopped, check for any standing water, especially in the basement. With our area's flat terrain and clay soil, water pools quickly. Use towels or a wet vac to clean up, and keep an eye on sump pits for rising water. If your sump pump isn't keeping up, we handle sump pump services, as power outages or pump failures are a common headache during emergencies.
Document any damage and call a licensed plumber if the leak involves the main supply, a corroded pipe, or you can't get water to stop. We also offer leak detection and repair if you see water but don't know where it's coming from. Fast action here saves on bigger repairs later.
Common Causes of Plumbing Emergencies in Hickory Hills
Our older housing stock and tough winters make certain emergencies more likely, including:
- Burst pipes, often from freezing temperatures or stress due to corrosion.
- Main shutoff failures due to age or mineral buildup, common with older, rarely-used valves.
- Clogged or broken drains and sewers. Flat terrain and clay soil can cause backups, especially after heavy summer storms. If backup is an issue, drain cleaning or sewer line services may be needed to clear blockages and keep water moving in the right direction.
Being aware of these common problems helps you spot trouble before it turns into an emergency. Annual inspection of your main valve and visible supply lines is a smart move, especially before deep winter sets in.
Planning for Shutoff to Minimize Damage and Costs
The quicker you stop the flow, the smaller the bill for water damage and plumbing repair. Teach everyone in the house, including teenagers and older kids, where the main shutoff is located and how to use it. If your valve is original to the home or hard to turn, get it replaced before you have a crisis. We recommend this as part of annual home maintenance.
For households with updates or additions, make sure you know if there's more than one shutoff. Some newer homes or remodels have extra shutoffs for convenience, but the main is still your best bet in a major emergency. If you're not sure, or your plumbing looks like a maze, our emergency plumbing team can help assess your system and get you prepared.
