I've looked online and couldn't figure out exactly what I need to do.
I just moved to a new flat and found out that the bathtub drain plug doesn't work well, so water leaves from the bathtub pretty quickly, even when it's "closed". I would like to know what to do to solve the issue.
Here are the facts I have gathered so far:
My bathtub is from the brand "Grohe" (and I live in Germany, FWIW).
There is a mechanism on the side that makes a small plastic part go up and down (when it goes up, it pushes the drain plug up to open it and when it goes down it just lets the drain plug "fall").
The joint on the drain plug doesn't look that bad (at least to my unexperienced eyes).
If I really push on the drain plug with my whole weight, the water indeed doesn't flow away.
What I'm a bit puzzled about:
If it's a problem with the joint, can I replace the joint alone or should I replace the whole drain plug? Can I buy generic parts or it needs to be the exact same reference?
Is it normal that the mechanism on the side to open/close the drain plug doesn't actually pull the drain plug down when closing it? In other words, is it expected that "only" gravity is enough?
Thanks in advance for your help and if you need more pictures, don't hesitate to ask 🙂
