If your shower turns cold after five minutes, something changed — either the heater is failing or your household outgrew it.
The dip tube sends cold water to the bottom of the tank. When it cracks, cold water mixes at the top and you get lukewarm water quickly. Cheap part, common failure on units 10–15 years old.
Electric heaters have two elements. When the lower one fails, only the top third of the tank heats. Classic symptom: hot for a few minutes, then cold.
A tank half full of scale is a tank half full of hot water. A flush helps if it's caught early.
Check for 120°F. Higher settings scald; lower settings run out sooner.
A 40-gallon tank supports about two back-to-back showers. Bigger family, soaking tub or rain shower head? You've outgrown it. Options: a larger tank, a hybrid heat pump unit, or a tankless water heater that never runs out and cuts energy use 20–30%.
