Start with safety
If you smell gas, see sparking or cannot stop flooding, leave the property and call 911 and your utility provider from a safe location. Do not enter standing water near electrical equipment or attempt gas or electrical repairs yourself.
Describe the problem before choosing a fix
Note whether the problem affects one fixture or the whole home, whether hot water runs out or never arrives, and where you see a leak. Rumbling, an error message or a change in recovery time can also help a technician investigate, but symptoms alone do not establish the cause.
No hot water or less hot water than usual
Water at a connection, valve or around the tank
A displayed error, unusual noise or repeated shutdown
Repair or replace?
A valve, connection or other component may be repairable; a leaking tank body generally means replacement. The unit's condition, age, repair quote and installed replacement price all matter. If a leak could damage a finished basement or another unit, discuss that risk as part of the decision.
Plan for the property
In a DC rowhouse, a tight basement, stairs or existing venting can affect the equipment that fits. In a condo or shared building, ask management about access, work windows, documentation and shutoff coordination. Requirements vary by address and scope, so confirm any permits before scheduling.
Prepare for a quote
Share the service address, symptoms and whether the heater is gas, electric, tankless or another type. Photos of the whole unit, its model label, and its vent or connections help the team review the setup. For a replacement, mention access limitations and how many fixtures may run at once.
The takeaway
A useful repair plan starts with a safe assessment of the problem and the actual installation. Compare the diagnosed repair with replacement options, and confirm the scope, timing and applicable requirements before work begins.
