Replace Old Water Heaters or wait to fail?
I have 3 old water heaters in a chain (water into #1, which feeds #2, which feeds #3, which feeds the house) in my vacation townhome. Trying to decide if I should swap them out for one new 75 gal tank, or just wait for 1 or 2 to fail before incurring the expense. Seems to me that if one or two fail, I can just bypass them in the chain and keep on showering. Make sense?
