Thanks for replying.
Your water heater is past or at it's life expectancy. Water heaters life expectancy is 8-15 Years depending on where you live , water quality ,usuage ,etc. Your water heater could very well fall under the time we where having the dip tube issues. Most water heaters with dip tibe issues had a cut off time around 1997 but there was some with a cut off time of 1999. Look like it's time to replace.
