Water heater repair and replacement

No hot water, rusty water, a puddle under the tank or a rumbling heater. Here is what usually causes it and what replacement involves in Chicago and the suburbs.

Safety

Safety first A leaking tank, a constantly discharging relief valve, scorch marks near the burner or a gas odor are reasons to stop and call. If you smell gas, leave and call the utility or 911 from outside.

Repair or replace?

Repairs (thermostats, elements, ignition parts, valves) make sense when the tank itself is sound. A leaking tank cannot be repaired. Age, efficiency, how the unit is vented and changes in household needs all factor in. Tankless units change gas, venting and sometimes electrical requirements, so they are a bigger project than a like-for-like swap.

Permits in Chicago

The City’s Express Permit Program instructions for plumbing work include repairing or replacing an existing water heater. Replacing a domestic water heater is listed outside the monthly plumbing-maintenance permit category.

Permits in the suburbs

Suburbs set their own rules. For example, Orland Park states that permits are required for all water heater installations. Others, like Naperville, list some exempt work but not water heaters — confirm locally. Naperville water heaters

What affects the cost

We do not publish prices. Providers typically consider: tank vs tankless, capacity, fuel type, venting changes, access (tight closets, stairs), code upgrades such as expansion tanks or relief-valve piping, haul-away and permits. Ask how the price is calculated before work starts.

Licensing

In Chicago, most plumbing work must be done by a licensed and bonded plumbing contractor holding a City of Chicago license in addition to State licensing. In the suburbs, plumbers are licensed by the State and each municipality runs its own permits. Chicago permits · Illinois licensing

Frequently asked questions

Do I need a permit to replace a water heater in Chicago?

The City lists water heater repair or replacement in its Express Permit instructions for plumbing work, done by a City-licensed plumbing contractor. Confirm with the contractor that a permit will be pulled.

Should I flush my water heater?

Many manufacturers recommend periodic flushing to reduce sediment. Follow your unit’s manual; on older tanks a valve that has not been opened in years may leak.

Is tankless better?

It depends on hot-water use, gas supply, venting and budget. It is a different installation, not a simple swap.
