I've got a 4 year old 50 gal.GE gas water heater(12 year warranty) that puts
out hot water at first but then there is a temperature drop in the water
afterwards. Occasionally you hear a pssshhht sound coming from it, kind of
like the noise you'd hear if a pressure relief valve was going off.
I have city water, but I've had some shower heads that have limed up on me
so I assumed the water heater has limed up. I've drained it a couple of
times now with no change. I called up Tri Bros. Chem. to purchase some Mag
Erad to try and flush any lime deposits out and the guy said I should
inspect the dip tube before I buy his product.
Is there any way a dip tube could deteriorate after four years? And should I
even be doing anything to the heater myself considering it's still under
