Water heater repair in Waukegan, IL

Lake Michigan water from the city plant

The City of Waukegan operates its own water filtration plant on the lakefront, which opened in 1928 and draws Lake Michigan water through an intake that reaches more than a mile offshore. The plant filters and disinfects the water before pumping it to homes in Waukegan and a few neighboring areas such as Beach Park. The city has been rebuilding sections of the aging plant in recent years while keeping it in service.

Lake Michigan water is moderately hard, so Waukegan tanks collect some scale, but far less than in towns that rely on deep wells. The more noticeable trait is temperature. In February and March, water can arrive close to freezing, and even in August it rarely gets much warmer than the 60s. That steady cold is the main reason Waukegan heaters run long cycles and lose output in winter.

Older housing near the lake and downtown

Waukegan's oldest homes sit on the bluffs above the lakefront and around downtown, in neighborhoods such as the Near North historic district and the streets around Bowen Park. These are late 1800s and early 1900s houses built over full stone or brick cellars, and the water heater usually stands near a masonry chimney, often beside an old boiler or a newer furnace.

Further west, neighborhoods built from the 1920s through the 1960s, including areas around Glen Flora Avenue, Washington Street and Lewis Avenue, have bungalows, Cape Cods and ranches with basements or utility rooms. Many have been converted to two-flats or rentals over the decades, and some still run their original gas lines and galvanized plumbing.

Newer subdivisions on the city's west side, closer to Gurnee, mostly date from the 1980s onward and put heaters in basements or garages, sometimes with power-vent or high-efficiency units.

Lake winds, cold snaps and wet basements

Waukegan winters are raw and windy, with cold air off the lake and periodic lake-effect snow. During deep cold, such as the January 2019 polar vortex, which drove northern Illinois far below zero, drafty basements and cold chimneys can make gas heaters struggle to vent properly.

Heavy spring and summer storms flood basements in older neighborhoods when sewers back up. A water heater that sat in floodwater needs inspection, and one whose burner or gas control was submerged should be replaced. Raising the heater on a stand and installing a backwater valve are common improvements in flood-prone basements.

The problems plumbers see most in Waukegan

• Chimney venting problems in old lakefront homes where a furnace upgrade left the gas heater in an oversized flue.
• Corroded gas connectors and galvanized pipes in damp basements of older houses.
• Winter no-hot-water calls when near-freezing lake water overwhelms an undersized tank; start with no hot water troubleshooting.
• Basement flood damage after storms back up the sewers.
• Thermocouple and pilot outages in drafty basements on windy nights.
• Leaking tanks in rentals where heaters run well past their expected life.

Typical water heater prices in Waukegan

Waukegan's prices reflect the Chicago metro labor market. Steep stone basement stairs, corroded supply lines and chimney work in older homes add to the cost of an otherwise simple swap.

Permits and licensing in Waukegan

Plumbers in Illinois carry licenses issued by the Department of Public Health, which also registers contracting firms. For a Waukegan address, the city's Building Department issues the heater permit, and an inspector then checks the gas hookup, flue, combustion air and relief line.

Neighboring communities such as Gurnee, Park City, North Chicago and Beach Park handle their own permits or rely on Lake County. Before work begins, make sure the permit is part of the written estimate and that the plumber's IDPH license is current.

Sizing for cold lake water

Because Waukegan's inlet water is so cold, a tank's real hot water output in winter is lower than its rating suggests. A household that gets by with 40 gallons in summer may want to step up to 50 gallons or a fast-recovery gas model to avoid cold showers in February. Tankless heaters work well but need a properly sized gas line, since they have to lift lake water by a large margin.

Venting in old lakefront homes

Many Waukegan homes built before 1940 share a brick chimney between the furnace and water heater. Once that furnace gives way to a condensing unit with a PVC pipe out the side wall, the heater is stranded in an oversized masonry flue that can quit drafting in winter. Plumbers usually answer that with a stainless liner matched to the heater, or by moving to a power-vent model with a dedicated pipe.

An inspector will look closely at venting during a replacement in these houses. Have a plumber check for backdrafting if you see soot or scorch marks near the draft hood, smell exhaust in the basement, or your carbon monoxide alarm sounds.

Repair or replace in Waukegan

If the tank is still under about nine years, putting in a new thermocouple, relief valve or gas control is generally money well spent. Older tanks that leak, show rust at the base, or were damaged in a basement flood should be replaced. Nicor Gas and ComEd have each run rebate programs at times, and those can narrow the price gap to a heat pump or condensing unit. Our replacement walkthrough covers the steps.
