Water heater repair in Green Bay, WI

Lake Michigan by pipeline

Green Bay sits at the mouth of the Fox River on the bay itself, but the bay is not its drinking water. Since the 1950s the Green Bay Water Utility has drawn water from the open lake east of the city and piped it many miles inland after treatment. Several surrounding communities, including De Pere, Allouez, Bellevue, Howard, Ledgeview and Lawrence, took a different route: they formed the Central Brown County Water Authority and in 2007 began receiving Lake Michigan water through a pipeline from Manitowoc.

Before that switch, those suburbs relied on deep wells in a sandstone aquifer that had been dropping for decades and carried radium. The change matters for water heaters. Lake water is only moderately hard, roughly 7 to 8 grains per gallon, so tanks scale up far more slowly than they did on the old wells. If you own a heater that was installed before 2007 in one of those suburbs, it likely carries extra mineral buildup from its well-water years.

Cold water for half the year

The real challenge in Green Bay is temperature. Northern Lake Michigan stays frigid, and by the time it reaches homes in January the supply can be in the mid 30s. Even in late summer it barely touches the low 60s. Your heater must lift that water by 85 degrees or more in winter, which shortens the run time of every tankful and keeps the burner firing nearly nonstop when the household is busy.

Families often first notice it as lukewarm showers in February that seemed fine in September. Before calling for a repair, it helps to know that a healthy but small tank simply produces less usable hot water when the inlet is that cold.

Green Bay homes and their basements

Older neighborhoods on both sides of the Fox River, such as Astor Heights near downtown on the east side, the Navarino area and the Fort Howard area on the west side, hold frame houses and foursquares from the late 1800s into the 1920s. Their basements are often stone or block, with low ceilings and the heater beside a brick chimney. Post-war bungalows and ranches spread out from there, around Joannes Park, Baird Creek and the streets near Lambeau Field, nearly all with full basements.

Newer construction on the far east side and out toward Bellevue, Howard and Suamico tends to have high-efficiency furnaces and power-vent or direct-vent water heaters with plastic pipe through the rim joist. Those vent terminals sit close to the ground and can be blocked by snowdrifts, a problem most southern homeowners never face.

The problems plumbers see most in Green Bay

• Lukewarm February showers when a 40-gallon tank cannot keep pace with near-freezing lake water.
• Snow-blocked sidewall vents on power-vent and tankless heaters after a heavy storm or plowing.
• Pilot outages and thermocouple failures when subzero wind backdrafts an old chimney and snuffs the standing pilot.
• Frozen supply lines along outside basement walls in older east and west side homes.
• Condensation and rust on cold-water fittings above the heater in damp basements.
• Leaking relief valves that drip onto the basement floor because no expansion tank was ever installed.

Typical water heater prices in Green Bay

Northeast Wisconsin labor costs are moderate. Expect a higher bill during a January cold snap, when every plumber in Brown County is answering no-heat and no-hot-water calls, and for homes where an old chimney must be relined before a new atmospheric tank can pass inspection.

Wisconsin licensing and Green Bay permits

Plumbing credentials in Wisconsin, from apprentice registration through journeyman and master licenses, are issued in Madison by the state agency known as DSPS. Before letting someone disconnect your gas heater, plug the person's name into the DSPS credential search and make sure the license is active.

Within the City of Green Bay, water heater replacements are permitted and inspected by the city's building inspection staff. The inspector checks the gas line, vent connection and clearance, relief valve discharge and, increasingly, the expansion tank. Allouez, Ashwaubenon, De Pere and other neighboring communities each run their own inspection departments, so the permit follows the address, not the plumber.

Venting through a northern winter

Atmospheric gas heaters rely on warm exhaust rising up a chimney. In an old Green Bay chimney with a cold exterior wall, that draft can stall on bitter nights or reverse when strong wind hits the top. A heater whose flame flickers or goes out on windy nights should have its draft tested and the chimney inspected; relining the flue in stainless or trading the tank for a power-vent model usually cures it.

Power-vent and direct-vent units avoid the chimney entirely, but their outdoor terminals need attention after snowstorms. Keep the area around them clear, and make sure snow thrown from a driveway or a roof slide does not bury the pipes. A blocked intake or exhaust will shut the heater down, often in the middle of the night.

Sizing and upgrades for Brown County households

Because the incoming water is so cold, many Green Bay households are happier with a 50-gallon tank than a 40, and large families may need 75 gallons or a high-recovery burner. Tankless units can work well here when the installer plans for an 85-degree winter rise, and the gas meter and pipe often need upgrading to carry the higher input.

Wisconsin Public Service supplies natural gas and electricity in Green Bay and much of the surrounding area, and through Focus on Energy, the state's efficiency program, incentives for water heaters have been available at times. Heat pump heaters are an option in roomy basements, though they cool the space around them, which some homeowners welcome in summer and others notice in winter.

Repair or replace in Green Bay

Lake water is kind to tanks, so many Green Bay heaters last twelve to fifteen years. A single failed thermocouple, igniter, valve or vent motor is generally worth fixing while the tank is younger than about ten. If the tank is older, leaks from the body, or has never kept up with winter demand, replacing it with a larger or more efficient unit is usually the smarter money.

Around Green Bay

De Pere, a separate city a few miles up the Fox River, runs its own building inspection and is part of the Central Brown County Water Authority. Allouez and Ashwaubenon border Green Bay to the south and southwest with their own permit offices. Howard, Suamico and Bellevue have grown quickly with newer homes and their own village staff. Ledgeview sits on the Niagara Escarpment southeast of De Pere. Each issues its own permits, while the state license is honored everywhere.
