I installed one in my dad's house in 1974, he died in 2001 and the water heater was still working when we sold the house and they remodeled it in 2003. However he drained and flushed it out every year, had great well water. It was made for Cook's Hardware and had their label but I don't know who actually made it.
What a deal.
