My hot water heater is in the hot water closet in my kitchen.At least
once each year I hook up my water hose and I drain the sediment through
the hose on out into my back yard.

Home Depot,,, patented little fan to stir up the sediment??? I never
heard of that one before! Buy a water heater at a plumbing supply store.

A city permit to install your own water heater? Why? Just buy a new
water heater and install it yourself, or get a neighbor to do it for
you.
