Sediment build-up on the tank bottom may create varying
amount of noise, and if left in the tank will cause permanent
tank failure. In some water areas, you may not be able to drain
ali sediment deposits by simply draining the tank. In these
cases Mag-Erad (part no. 23600) can be used to help remove
the sediment deposits. This may be ordered from the Sears
Service Center. For ordering, refer to the
