Faulty wiring.
Yes, lightning can damage a pool light.
No, but it could cause similar appearing skin irritations.
I would not recommend it, the bubbles could get into the pipes of the pool which could cause problems with the water that runs out of the pipe. It is also could affect the chlorine in the pool.
No. It is a public pool and depending on the cause of your bleeding you could get it infected or spread what you have.
You probably need to replace the light switch
A bad or old light cord. Water or moisture getting into the light can. I hope you have a GFCI on the system. Call a professional pool tech to troubleshoot and advise. A replacement may be in order.
Yes, it is true.
yes a pool light is typically a sealed unit. this is to prevent water from entering the light and coming in contact with the electrical components of the light. if water were to enter the light it could damage the light fixture and also trip the light breaker or gfci. in addition in some situations if the light were not installed correctly/electrically protected correctly (with breaker and gfci) could cause a dangerous situation to bathers. to change the light bulb in a pool light fixture the light fixture must be brought above the waters surface and the lense with lense gasket removed bulb changed then lense with lense gasket replaced and the light reinstalled in the light niche in the wall of the pool below the waters surface. you must also use the appropriate bulb for the light fixture. this is not as simple as just picking up a bulb from home depot and threading it in as you would do with an outdoor flood light. light repairs should only be performed by a trained pool professional as it could be dangerous if not done correctly.
The start capacitor could be bad. Is the Breaker tripped? Do you have a timer? Is it working properly?
No, you would not be able to survive a tsunami in a pool. Tsunamis are large, powerful ocean waves that can cause widespread destruction and are not contained to the size of a pool.
This depends on what kind of pool you have. If it's a permanent pool, such as one set in concrete, no that will not hurt it. If it is an inflatable pool, than yes, leaving it outside when it is not full could eventually cause damage.
Yes.. If the lite ring or facering are corroded the chemical ballance has been way off..
