Weak flow at one or two fixtures (likely local). Here's what to do about pressure problems in Chicago — including the local factors that change the advice.
Do this right now
Check if it's one fixture or everywhere
One fixture = aerator, cartridge, or supply line. Everywhere = main valve, pressure regulator, or supply problem. This single test directs everything.
Clean the aerators
Unscrew faucet aerators and the showerhead, soak in vinegar to dissolve mineral scale, scrub, reinstall. This alone fixes a huge share of 'low pressure' complaints.
Check the main shutoff
Make sure the main valve is fully open — a partially closed valve after plumbing work is a classic gotcha.
Ask a neighbor
If neighbors have the same issue, it's the municipal supply — call your water utility, not a plumber.
Call for the deeper causes
Call (844) 699-1165. Failing pressure regulators, corroded galvanized pipe, and hidden leaks need a pro's diagnosis.

What makes pressure problems different in Chicago
- Moderately hard Lake Michigan water — scale buildup is the #1 pressure killer in this area.
- brick bungalows and vintage two-flats, nearly all with basements — older pipe materials narrow with age here.
- In Chicago, polar-vortex winters with brutal freeze-thaw cycles
- Combined sewers mean heavy rains back up into basements — sump pumps and overhead sewers are Chicago essentials
Neighborhoods
If you're in Lincoln Park, Wicker Park, Logan Square, Hyde Park, Naperville, Aurora, Evanston, Pilsen, Oak Park, Joliet, or anywhere across the Chicago metro — Chicago, Aurora, Naperville, Joliet, Elgin — the steps above apply.

What to tell the pro when you call
- Whether it's one fixture, one area, or the whole house
- How long it's been happening and whether it's worsening
- Your home's age and pipe material if known (galvanized = prime suspect)
- Your pressure reading if you tested with a gauge
- Whether neighbors are affected
