Water heaters in Delaware
Delaware homes with basements usually keep the water heater there, often beside the laundry and floor drain, so a failing tank floods the basement first if the drain is slow.

Water heaters in Delaware: what to know
Humid summers corrode tanks and connections in garages and basements, and cooler winter water makes heaters work harder. Newer suburban homes on slabs often keep heaters in garages or closets.
Replacements need a permit from the local office and a licensed plumber. Adding a drain pan and expansion tank is common.
- Climate
- Delaware gets periodic hard freezes and ice storms, often after mild spells, which catch exposed pipes off guard. Pipes in crawl spaces, exterior walls and garages are the first to freeze.
- Typical foundations
- Homes range from older rowhouses in Wilmington to newer suburban construction, with both basements and slabs common. Most common: basements.
Water heaters services
Water heater repair
If 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.
