It lasted its 6 year warranty. Richmond natural gas 50 gallon 38,000 btu. The prior tank lasted 10 years, AO Smith of similar size. Menards sold me this first and last Richmond. Home Depot has Rheem which looks fishily like the Richmond I have now, hmmm. I can mail order AO Smith or Bradford-White. I could also spend the coin and go tankless. Looking for recommendations. 4 bedroom, 3 1/2 baths for three people, jacuzzi whirlpool tub in master.
