About two weeks ago my hot water started sputtering as if air had gotten into the lines. I also noticed the water coming out cloudy sometimes. I drained and flushed the heater and this seemed to cure the sputtering.

After draining the heater i noticed the hot water started coming out real, real hot. There also does not seem to be enough hot water to fill the tub (we have a 50 gal elec). I can take a shower without problem; but, the hot water seems to run out about half way filling the tub. My daughter is not happy.

Today the sputtering returned and so did the cloudiness. I have a Rheem electrical water heater and it is only 1 year old. Any thoughts on what this could be?

Thanks for your help.
