Des Plaines Plumbing Problems and First Steps

Water Bought Through Evanston
Evanston’s water page lists Des Plaines as a wholesale customer, and during the 2025 northwest main leak neighboring Mount Prospect planned interconnections with Des Plaines. The water bill names your provider. Everything after the meter belongs to you.
River Floodplain and Basements
The river floods low blocks in wet years. Test the sump pump each spring, keep a battery backup and consider a backwater valve.
Postwar Ranches and Cape Cods
Much of the housing was built from the 1950s through the 1970s. Original water heaters, shutoffs and supply stops are often past their expected life, and many homes have galvanized supply and clay laterals.
Condos and Apartments Near O’Hare
Many residents live in multi-unit buildings where stacks and heaters serve several homes. Tell the plumber your unit and whether neighbors are affected.
Know Your Shutoffs Before the Cold
Power outages in winter storms leave water heaters and supply lines without heat. Insulate exposed pipe in crawlspaces, garages and rim joists, shut off and drain outdoor spigots and disconnect hoses before the first freeze. Water that comes back slowly after a cold night is often a partly frozen line, not a broken one.
Hardness, Iron and Softeners
Well and aquifer water in much of central and northern Illinois is very hard and often carries iron. Soak aerators and showerheads in vinegar every few months where crust forms. If the unit is old, water heater repair can tell whether a flush will help.
Meter Test for Hidden Leaks
Unexplained water bills are often the first sign of a hidden leak. A damp slab edge, a warm floor spot or a stained basement ceiling narrows it down. Finding the exact spot keeps the repair small. When water will not stop, emergency plumbing help is a call away.
When Drains Keep Backing Up
Backups that return after cleaning usually mean roots, a belly or a cracked pipe. A camera run shows whether roots, a belly or a break is behind repeat clogs. Use drain cleaning for clogs and sewer line repair when the camera shows a break.

Quick Checks Before You Call a Plumber in Des Plaines
Look under every sink with a flashlight and a dry paper towel. Touch the supply lines, the stops and the trap, and look for damp spots, mineral crust or swollen cabinet floors. Replace braided lines that are more than about ten years old before they fail. Photograph anything that looks suspect so a plumber working in Des Plaines can see what you saw even if the drip is intermittent.
Check the expansion tank on systems that have a closed loop or a pressure-reducing valve. A small tank on the heater supply absorbs the pressure rise when water heats. If it is waterlogged, the relief valve may drip and pipes may bang. Tapping it should give a hollow sound at the top and a solid sound at the bottom. A plumber can test the air charge and replace the tank if needed.
Make sure dishwasher drains have a high loop or an air gap. Without one, dirty sink water can flow back into the dishwasher, and the unit may drain slowly. Check the hose for kinks and clean the air gap cap if there is one. If the sink backs up when the dishwasher runs, mention it, because the garbage disposal knockout plug may also be left in place.
Test every shutoff valve under sinks and behind toilets once a year by closing and opening it gently. Valves that have not moved in years can seize or leak when turned, so replace any that drip or refuse to close while the plumber is already on site. A set of working stops lets you isolate one fixture instead of shutting off the entire house when something fails in Des Plaines.

Frequently Asked Questions — Plumbing in Des Plaines, IL
What do I do if water is spreading through my Des Plaines, IL home?
Close the main valve and call the number on this page. Enter your ZIP code, stay on the line and describe the leak. Ask for the company name and arrival window, and follow the emergency plumbing guide while you wait.
Is a leak in Des Plaines, IL handled by the city water department or by a plumber?
The city handles the main in the street and the meter. Everything after the meter is the owner's responsibility. A plumber can locate a leak in the service line or under the slab and tell you which side it is on.
Where does Des Plaines water come from?
Lake Michigan water treated at the Evanston plant and delivered through a water commission. Your bill confirms your provider.
How do I keep my Des Plaines basement from flooding?
Test the sump pump each spring by pouring water into the pit, keep a battery backup and make sure downspouts discharge well away from the house. A backwater valve on the sewer line helps in heavy storms.
Do older Des Plaines homes in postwar neighborhoods have galvanized or cast iron pipe?
Houses built before the 1960s often still have some galvanized supply or cast iron drain. A written inspection with a camera run shows how much life is left.
Is Des Plaines water hard, and what does it do to my pipes?
Water here is hard. A softener helps some homes, but a flush every year and a look at the anode rod go a long way. A plumber can test hardness and advise.
How do I protect Des Plaines pipes in a cold snap?
Pipes in attics, crawlspaces and outside walls are the ones that burst. Insulate them, let a tap drip on the coldest nights and keep the main shutoff easy to reach.
