It is possible to purchase used hot water heater parts on online stores such as Amazon and eBay. Both sites offer a large inventory of used, returned, refurbished and warehouse-damaged water heater parts and accessories from different sellers in the United States and other parts of the world.
The Amazon Warehouse Deal department, in particular, sells used water heater products in good condition that do not meet Amazon's strict "new item" standard. Amazon has verified the functional and physical conditions of the products in the warehouse deal inventory. The online auction site eBay, on the other hand, gives consumers the option to buy a fixed priced item or strike deals with a seller through the site's auction system.
