Information on water heater problems can be found on websites that have a do-it-yourself plumbing section, such as FamilyHandyman.com or WaterHeaterRescue.com. Replacement parts for a water heater can be found at hardware stores, such as Lowe's, or at online marketplaces, such as Amazon.com.
Plumbing websites typically have a repair guide for the most common hot water tank problems, allowing the user to read step-by-step instructions to fix the issue. These guides typically have a difficulty rating for each repair, which allows the user to determine if he should attempt to do the repair or seek professional assistance. The guides also instruct the user on which replacement parts are needed.
