Attic Water Heater Replacement in Hockessin
Some homes from the late 1970s through the mid 1990s contain polybutylene pipe, which is best replaced before it fails. Some homes, especially those built in certain eras, have water heaters in the attic.

Frequently Asked Questions About Water Heater Replacement in Hockessin
Most standard gas or electric tank replacements cost $1,400 to $3,000 including the heater, labor and typical code upgrades. Attic installs, larger tanks or relocations can raise the cost to $3,000 to $4,500.
Most replacements take two to four hours. Attic installs or relocations can take longer.
We install Bradford White, Rheem and A.O. Smith water heaters. Each offers dependable performance and a range of warranties.
Most new water heaters come with a manufacturer's warranty ranging from 6 to 12 years on the tank and components, depending on the model and brand. GNV Plumbing also provides a labor warranty on our installation, so your investment is protected.
Choosing the right size depends on the number of people in your household, their hot water usage habits and peak demand times. Our technicians will calculate the right GPM (gallons per minute) for tankless or gallon capacity for tank models so you never run out of hot water, especially in multi-bathroom Hockessin homes.
New water heaters usually come with a manufacturer's warranty on the tank and parts, usually ranging from 6 to 12 years. GNV Plumbing also provides a labor warranty on our installation, giving you added peace of mind. Specific warranty details vary by brand and unit.
Leaks at the base, rusty water, rumbling noises, inconsistent hot water and an age over 10 years are common signs. A leaking tank should be replaced right away.
Flushing a traditional tank water heater once a year is recommended in most homes. Private wells are common in rural Delaware, and they can carry iron, nitrates, or low pH that calls for testing and treatment. This helps remove sediment buildup, which can reduce efficiency and shorten the lifespan of the unit. Regular flushing can also prevent scale from damaging heating elements.
