there are two ways, increase the pilot pressure if possible or redrill the pilot hole with a specialty set of orifice bits...many times its easier to order the orifice youre looking for
Most pilot lights are not adjustable. If it's not working properly the usual solution is to change the thermocouple.
If the tub is not getting hot water the issue is probably with the hot water heater. The hot water heater may have tripped a breaker or the pilot light went out.
Gas not turned on to water heater. Gas valve on water heater not set to pilot setting. Faulty gas valve. Igniter for lighting pilot not working.
Have you turned the control from Pilot to On? Have you increased the temperature setting?
is the lines on the thermal coupler and pilot light for a hot water heater supposed to get hot
"Pilot" is only when initially igniting your water heater. Some manufacturers state to leave it on "Pilot" for so many minutes before turning to on but this is only temporary. It should be then turned to "On" and then if you have a low, medium or high setting or degrees adjustment, adjust the temperature setting. Remember that most local plumbing codes and water heater manufacturers recommend a temperature of no more than 120 degrees F.
Turn it off at the fuise box, whyheat water when your not there
THERMOCOUPLE or defective gas valve
Same as any hot water heater. Turn the gas valve to off.
No, it is not dangerous. (Unless you are working with a water heater that is 20+ years old.) In any modern hot water heater, if the pilot light goes out a fail-safe will go off - preventing gas from leaking out. Also, there is a sensor so if there is not enough air-flow or oxygen with the water heater, it will shut off the gas.
It will not -- It must be wind comming down your flue and putting it out
Sounds like you need a thermocouple.
