We purchased 56 Rheem water heaters for our senior housing community in Eudora Kansas. 12 of the tanks have had failures within the first 4 years of service. None of the plumbing contractors want to work on the Rheem water heaters because they were purchased from Home Depot and are told that parts are not easily available. We are slowly switching out the tanks to another brand that was recommended by our plumbing contractor. We will no longer be purchasing any Rheem water heaters.
