Long Story:
New In-Ground 20X40 Liner pool installed two years ago. When the installer was putting in the light they broke the screw on the top of the niche that holds the light in. They guy has been unresponsive (Big Surprise in the pool industry) to fix it so I have been lookin at my options and wanted opinions.

1. Can I use a air drill to drill the center of the broken screw and then use a screw extractor ? Leave the water as is and when I am done just disasseble and re-oil the drill ?? Would a standard air drill work under water ?

2. Lower the water to the screw level and use a cordless drill ?
(I have well water and I prefer not to drain)

3. Lower the water below the complete light Niche and replace it. I have a built in Secure-a-Matic electric cover that is currently out for service that is in a recessed housing by the light that with it out makes the niche accessable.

The light has a tab that holds it in the bottom of the Niche and the screw on the top.

My cover will be out for a couple of weeks so this is my best time to resolve this issue .
