My husband and I live in Virginia and our well is 320 feet deep. We have replaced 2 water heaters in the past 5 years from rust so after some research on why water heaters go bad I took a chance with this product and purchased it in October 2018. Their product arrived in 2 days and was installed in our 1 year old heater. The seller recommended we flush the heater so we did and it was full of chalky white rocks from I think from the old anode since it was only a wire in the tank. We purchased another one in March 2020 for a second water heater for our new addition. My husband drained the old heater since we had to move the tank to a new location and the water was clear from white rock parts. We are satisfied with this product and how it was represented on their website.
