Water heaters in Buffalo, NY
Most tank water heaters last about 8 to 12 years. A plumber can often repair a heater that stops making hot water, but a tank that leaks from the bottom has failed and needs to be replaced. Tankless heaters last longer but cost more to install, especially if the gas line or venting has to change.

Water heaters services in Buffalo
Water heater repair
UrgentIf a gas water heater has no hot water, the pilot, thermocouple or gas valve is the usual cause; on an electric heater it's usually an element or thermostat. Those parts are repairable. A tank that leaks from the bottom can't be repaired and needs to be replaced.
Water heater replacement
A leaking tank or a heater past about 10 years old is usually replaced rather than repaired. A proper install includes a permit, correct venting (adjusted for altitude where needed), an expansion tank where required, a drip leg on the gas line and a relief valve discharge pipe.
Tankless water heaters
A tankless water heater heats water as it flows, so it doesn't run out, but it needs a larger gas line, its own venting and a unit rated for your elevation. Installed correctly and descaled regularly, it can outlast a tank heater.
Local conditions
Water heaters in Buffalo: what's different
Cold incoming lake water makes basement water heaters work harder in Buffalo, and heaters in Buffalo doubles often sit side by side in a shared basement.
Replacement is a good time to check venting and add an expansion tank.
Permits come from the city, and work must be done by a licensed master plumber.
Many heaters in older basements sit beside floor drains, so a failing tank can flood the basement if the drain is slow. Annual flushing removes sediment.
