Lukewarm water from your RV heater is typically caused by a failing heating element, sediment buildup, or thermostat issues. Most problems can be fixed by replacing the heating element, flushing the tank, or adjusting the thermostat.
RV black tank sensors reading full when empty are usually caused by waste buildup on sensor probes. Clean them using tank rinse chemicals, sensor cleaners, or the ice cube method to restore accurate readings.

Sanitize your RV water tank after extended storage, especially after hot Arizona summers. Use 1/4 cup bleach per 15 gallons, let sit 4+ hours, then flush thoroughly.
