Snap Shower

The filter on my shower drain is out. I bought a replacement that has 4 pins that are supposed to pressure?
The replacement is supposed to activate, but nothing to break the leak occurred in black rubber and there seems to be something to put in. The little arms that slope has left points down and he must have been sealed Silicone him. It's what I do.
According to "snap on" you purchased may be possible to bend a bit and locks help maintain strength in the leak. But it will not work if the complement of metal type. Good luck …
