My pool sweep is out of service so I have been manually vacuuming my pool. I ran my vacuum over my pool light and it pulled out (oops!). I quickly pushed it back in but I do have a couple of questions.

1) Should that have happened so easily?
2) Is there anything I need to do to secure the light at this point? It seems to stay in pretty well but it is not flush.

My pool is an IG gunnite, as you can see from my signature.
