Steps To Replacing Your Water Heater

Call Us

We believe the first step in diagnosing your problem starts when you call us. You'll always speak to a plumber when you call HPC.

Schedule Appointment

Scheduling a water heater problem quickly is usually pretty important. Especially if it's leaking. We make every effort to replace your leaking water heater on the same day but sometimes a next day replacement is the only solution.


In order to give you an accurate price we must visit your property to check the water heater and it's connections. We'll determine any required code upgrades and identify any other issues before giving you a firm quote.


Once we have agreed on the price we will obtain the water heater and perform the replacement. Most water heater replacements take anywhere from 3-5 hours on site. Some may take longer depending on location and other conditions.


Upon successful completion of the replacement we will ask for payment. HPC accepts cash, check and card.


The final step is to register your water heater with the manufacturer for warranty purposes. HPC will register your new water heater within 5 days of installation.

Other Information Regarding Water Heater Replacements

Hanahan Plumbing Co provides and installs State water heaters. In some cases we may install AO Smith or Ruud.

HPC does not install water heaters provided by the owner because we will only warranty materials that we provide. We do not install or provide warranty service for water heaters purchased from Lowes or Home Depot. 

Many homeowners call us wanting to know if we work with home warranty companies. The answer is no, we will not perform any work for a home warranty company nor will we provide them with diagnoses, price break downs or invoices.
