Hi folks,
I was hoping for some assistance on how to remove this particular type of bathtub drain, in order to be able to unclog it with a plumbing snake, long hook, etc.
The surrounding white ring feels like it's made of plastic, which is as deep to the point of the metal component with the three prongs.
The middle golden thing is spring-actuated, which is used to block the drain - the blocking cap meant to be on it was removed to take this photo.
Do I have to pry it from, or twist the white ring part? Try to force it upwards with pliers/hooks on the metal grate? Is it possible to even remove at all? Any help or advice would be greatly appreciated!
