NOT ENOUGH HOT WATER

1. Not Enough Hot Water

2. Thermostatic Mixing Valve

3. Check Lower Heating Element

Make sure water heater is not undersized. Seasonal

variations in cold water temperatures and hot water

usage can generate “not enough hot water” complaints.

Faulty shower controls or defective thermostatic mixing

valves can also cause this symptom.
Set both thermostats to 120˚F.
