The repair-or-replace call goes wrong when tank age and repair cost are never written side by side.
Compare your tank's age, the repair quote, and a replacement budget line on one sheet.
Homeowners and renters who own or are responsible for a water heater.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Read the serial label and write the manufacture or install year.
Ask for a written repair quote that names parts and labor.
Set the total budget for a replacement, including installation.
Compare the quote to half the replacement budget and the tank age.
Your tank is 11 years old and the quote is $480. The sheet shows the repair cost against a 50 percent rule of a $1,600 replacement budget.
Use your own source and details. The example is not a record about a real person or organization.
