How do I replace a light in in-ground pool with water also if i remove it the will get into niche were was?

1. Check the ground around the pool. Before you disconnect any wiring, make sure that the area around the pool is dry. If there is standing water, it could come into contact with the electrical wires and cause a short circuit.

2. Turn off the power to the pool. There should be a circuit breaker or switch that controls the power to the pool lights. Turn this off before you start working.

3. Remove the old light fixture. To remove the old light fixture, you will need to unscrew the mounting screws. These screws may be located on the side or on the bottom of the light fixture. Be careful when removing the screws not to drop them into the pool.

4. Remove the old light bulb. Once the light fixture is removed, you can remove the old light bulb by turning it counterclockwise. Be careful when removing the light bulb not to break it.

5. Remove the old gasket. Once the light bulb is removed, you will need to remove the old gasket. The gasket is a rubber seal that helps to prevent water from leaking into the light fixture. Be careful when removing the gasket not to damage it.

6. Install the new gasket. Place the new gasket in the groove in the light fixture. Make sure that the gasket is seated properly.

7. Install the new light bulb. Screw the new light bulb into the light socket. Turn the light bulb clockwise until it is tight.

8. Install the new light fixture. Place the new light fixture back into the niche. Secure the light fixture with the mounting screws.

9. Test the light. Turn on the power to the pool and test the light. Make sure the light is working properly before you put the water back in the pool.

Tips:

* If the niche is leaking, you can try to repair it with a sealant. However, if the leak is severe, you may need to replace the niche.

* When replacing the light fixture, be careful not to drop any of the screws into the pool.

* If you are uncomfortable working with electricity, you can hire an electrician to replace the light fixture for you.
