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.
Calls are answered by a referral service that connects you with a local plumbing provider. How this works
Common symptoms and causes
| Symptom | Possible causes |
|---|---|
| No hot water | Pilot or ignition problem (gas), failed element or thermostat (electric), tripped breaker |
| Not enough hot water | Sediment, failed element, undersized unit, broken dip tube |
| Rumbling or popping | Sediment build-up in the tank |
| Rusty or discolored hot water | Tank corrosion, or old galvanized piping |
| Water around the base | Leaking fitting or valve — or a failing tank |
| Relief valve dripping | Pressure or temperature issue; needs attention |

Safety
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We do not publish prices.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.
