Have a 50 gal hot water heater that was not producing much hot water. I
replaced the Dip Tube and still not much improvement. The manufacture told
me to do a draw test, measure the temperature in 7 consecutive 5 gallon
buckets drawn from hot water.
The results were: 105, 111, 106, 101, 99, 96, 93
What could this mean, have not called the manufacture yet but would like to
get other opinions. Dip Tube installed improperly, would a hot water
heater go bad like this, any information would be helpful, thanks!
