The index

Everything we get called for

Tap any line to open it. These are the jobs that fill our board — roughly in the order Chicago asks for them, from the Tuesday-afternoon slow drain to the Sunday-night flood.

01 Emergency drain & sewer backup

Basement floor drains pushing up grey water, a laundry sink that won't empty, or the unmistakable gurgle from a tub when the toilet flushes. In a city with as much combined sewer as Chicago, the culprit is usually roots in the lateral or grease in the building drain — not the fixture you're staring at.

We rod the line, run a camera to the city main, and tell you honestly whether it's a clearing job or a repair job. If it's roots, you get the footage and a written quote before anyone cuts anything.

  • Main line rodding to 4" and 6" laterals
  • Hydro-jetting for grease and scale
  • Camera inspection with footage left with you
  • Root cutting and spot repair
02 Burst & frozen pipe repair

January in a two-flat with a north-facing wall is a plumbing problem waiting to happen. We thaw with controlled heat rather than an open torch, then repair or replace the split section — copper, PEX, or the galvanized that's still in a lot of pre-war buildings around Little Italy and Pilsen.

If the pipe is behind plaster, we open the smallest hole that does the job and leave the patch ready for your plasterer. We don't do drywall finishing, and we'll say so up front rather than surprise you.

  • Emergency shut-off and water removal coordination
  • Controlled thawing, no open flame near framing
  • Copper, PEX, and galvanized section replacement
  • Insulation and heat-tape recommendations for next winter
03 Water heater repair & replacement

No hot water, rusty water, or a puddle spreading under the tank. We carry 40- and 50-gallon gas and electric units on the truck, so most replacements are done the same day — including hauling the old tank out and getting the new one to temperature before we leave.

Tankless conversions are a bigger conversation: venting, gas line sizing, and whether your building's supply can actually keep up. We'll walk you through it and tell you when a tank is the better answer.

  • Thermostat, element, and thermocouple repair
  • Anode rod replacement to extend tank life
  • 40 / 50 gallon gas and electric swap-outs
  • Tankless install and descaling
04 Toilets, faucets & running water

A toilet that runs all night is a water bill you'll notice in six weeks. We rebuild fill and flush valves, replace wax rings and closet flanges, reset rocking toilets, and track down the faucet drip that's been keeping you up.

We stock the common cartridges for Moen, Delta, Kohler, and Grohe, so most single-fixture calls are one visit, not two.

  • Toilet rebuilds, wax rings, flange repair
  • Faucet and shower valve cartridge replacement
  • Garbage disposal replacement
  • Shut-off valve replacement (the one that won't close)
05 Sump pumps & backwater valves

Chicago's combined sewers back up in a hard spring rain, and a working sump pump plus a backwater valve is the difference between a damp floor and a ruined furnace. We install, replace, and test both — including battery backup so the pump still runs when the power doesn't.

  • Sump pump replacement and float adjustment
  • Battery and water-powered backup systems
  • Backwater valve installation and annual testing
  • Discharge line routing away from the foundation
06 Leak detection & repiping

A water bill that jumped with no visible leak, a warm spot on the floor, or a ceiling stain that keeps coming back. We use acoustic and thermal detection to find the leak before opening anything, then repair it or quote a partial repipe if the galvanized is at the end of its life.

  • Hidden leak location without exploratory demolition
  • Partial and whole-unit repiping in copper or PEX
  • Water pressure diagnosis and PRV replacement
  • Insurance-ready documentation of the damage and cause
07 Kitchen & bath rough-in

Remodel work for homeowners and small contractors: moving a sink, adding a basement bathroom, running a new supply for a laundry pair. We pull the City of Chicago permit when the scope requires it and coordinate the inspection so your GC isn't waiting on us.

  • New supply and drain runs for remodels
  • Basement bathroom and laundry additions
  • Gas line runs for ranges and dryers
  • Permit pulling and inspection coordination
08 Commercial & multi-unit service

Two-flats, six-flats, restaurants, and small commercial kitchens. We work on account for property managers and owners with more than one address, with itemized invoices per unit so you can bill it back cleanly.

  • Grease line jetting for restaurant kitchens
  • Stack and riser cleaning in multi-unit buildings
  • Preventive maintenance schedules
  • Net-30 account billing for property managers

Who shows up

A shop on Loomis, not a call center in another state

Chicago Drain Masters Plumbing 24/7 runs out of 920 S Loomis St, on the Near West Side between Little Italy and the UIC campus. The phone number on this page rings a dispatcher who knows the difference between a Grease line in a Randolph Street kitchen and a root-choked lateral under a bungalow in Portage Park — because those are the calls we take every week.

We're a small licensed crew, not a franchise. That means the person who answers is the person who sends the truck, and the plumber who arrives is the one who'll explain what they found in plain language before touching a wrench. If the honest answer is "this is a $180 clearing, not a $4,000 repipe," that's what you'll hear.

We work on the older housing stock that makes this city what it is — clay laterals, cast iron stacks, galvanized supply lines, and the occasional surprise from a 1920s remodel. We also work on new construction, because the same crew that understands a hundred-year-old drain understands a properly vented new one.

One number, answered around the clock. That's the whole pitch.

Where we drive

Chicago, and the blocks we know by name

We run the city limits and a short reach into the near suburbs. If you're not sure whether you're in range, call and ask — we'll tell you straight rather than send a truck that arrives in an hour and a half.

Get us on the phone

Call (464) 245-3033

This is the fastest way to reach us and the only way to book a truck. A live dispatcher answers 24 hours a day, every day of the year — including holidays, including right now.

Call (464) 245-3033

Have your address and a rough idea of what's happening ready. If water is actively running, shut off the main first — usually in the basement near the front wall, or in a closet on the first floor of newer buildings.

What people say after the water stops

"Called at 11:40 on a Friday night with water coming up through the basement drain. They were here before 1 and had the line open by 1:45. Showed me the camera footage of the roots."

Marcus D. · Portage Park

"Our water heater went on a Sunday morning. New 50-gallon in by early afternoon, old tank hauled away, no overtime charge. Straight answer on price before they started."

Elena R. · Logan Square

"Restaurant grease line, and they came after close so we didn't lose a service. Itemized invoice per unit for the building. We've used them three times since."
