A Knightdale homeowner requested a free whole home plumbing system check and also wanted a quote for water heater replacement.
Nick found the 40 gallon natural gas standard vent water heater in the storage closet at the back of the home to be 11 years old and leaking, and in need of replacement. He showed the homeowner's wife the unit and prepared an email estimate for replacement. The homeowner plans to sign the estimate once he can get to his email, so the installation can be scheduled when he calls.

Nick reported that everything went great and the new water heater was functioning properly.

Answered by our licensed technicians serving Knightdale.
A standard tank-to-tank replacement typically takes 2 to 3 hours. If we need to upgrade the gas line, modify venting, or switch from electric to gas (or vice versa), the project may take 4 to 6 hours. We provide a time estimate before starting.
It depends on your home's utility infrastructure and your priorities. Gas heaters have faster recovery rates and lower operating costs in most Triangle-area rate structures. Electric models are simpler to install and maintain. Hybrid heat pump electrics offer the lowest operating costs overall but need space and ambient warmth to perform optimally.
For a household of 2 to 3 people, a 40-gallon tank is typically sufficient. Families of 4 to 5 should consider 50 gallons, and larger households may need 65 to 80 gallons or a tankless system. We base our recommendation on fixture count and peak usage patterns, not just family size.
Yes. North Carolina plumbing code requires a thermal expansion tank on any closed plumbing system, which includes most homes with a backflow preventer or pressure-reducing valve on the main water line. We include expansion tank installation as a standard part of every water heater replacement.
