Answer 2

you have a question that can have many different answers . here is a list I would check first to your problem.

1. is your pilot light out or if a forced air WH is it plugged in with power to it?

2. Is your gas line on or do you have gas to your water heater?

3. look up your water heater manual guide and go through the trouble shoot guide list because the rest of the problems are so different from so many different kinds of water heaters and not knowing what kind of water heater you have it is impossible to answer.

Answer 3

Possibly because you are just using the hot water too much, or possibly because your tank has a problem keeping lit. -If you have to frequently re-light the pilot, you need a new 'thermocouple' .

Answer 4

Answer 5

Have you checked if the pilot light is on. If it is not, you will have to re-light it . Instructions near the regulator unit.
