Thnx!. It took more time then I thought it would (which is .... very common) nearly 12 hours in total. Emptying ( from shelves and stored stuff that was there) ripping it apart and building it back up. But i'm no plumber, it's not my daily job so it does take me more time.
Maybe I'll apply some paint, but really, I'm there max. twice a year for filter replacement and pressure check. It's worth having light, but paint .... i'm not so sure.
