when I 1st turn on the shower hot water faucet, the temp is good and hot. however, within about 15 seconds it goes luke warm. are there temp sensors in the faucet? can they be replaced? I have 2 showers that operate the same as the above.
Judging from the problems that you explained it’s very likely that you have a legitimate dip tube claim. Many of the major tank manufacturers have entered into a national class action settlement that will allow those homeowners with specific brands of water heaters, qualify for a “dip tube” replacement.
