Thanks for getting back to us so quickly Matt. Our heater is up and running again, and the install of your product was a piece of cake. I had anticipated the old anode would be depleted (tank is 2 years 4 months old and we have softened water) but found it was only partially so. That makes me feel very hopeful that we will get extra years out of it now that your product is "in charge" of the tank. Again, thanks for your impressively responsive, timely replies. Never before have I felt so complimentary towards someone who has got me in hot water!
Have a bountifully blessed week.
