How do I fill my Hot Water Heater (HWH) with water?

The water entering from the water source you selected will displace the air in the HWH and begin to fill.

Turn the HWH gas valve knob to the "Pilot" position, then push this knob in. Gas will NOT flow unless you are holding this down. It is a safety thing. Wait at least 1 minute, usually 2 and gas will begin to flow. Now try to light it.

Why does my water heater run out so quickly now?

Several things could happen. First check the shower head volume if shower's are too quick. A new shower head puts out about 2.5 gallons a minute. Some older heads put out 5 gallons a minute. Working with the shower head would double shower length in this case. In some cases, the dip tube on the cold water inlet has broken or worn. When this happens, it creates a short loop for the water, water at the bottom half of the tank will not be used.
