Not knowing too much about plumbing or water heaters when a friend recommended Todd's Water Heaters I called them.
The original hot water heater that was in our home when we purchased it had heated it's last drop of water.
They told me I could get a part fixed (almost the same amount of a new tank) or replace the water heater all together. I ended up replacing the water heater with a new tank because of the age but was really glad they explained options to me.
Great customer service and was impressed with the company!
