It is the second Spek mechanism that I install and unfortunately it leaks with occasional drops from where the rubber bladder is applied, that is, inside the drainage mechanism. It should not leak because the mechanism with its rubber bladders is new and there is no problem with its installation. Maybe over time and with the salts, the dripping will stop, but I do not consider this reasonable.

Super complete packaging! Everything is included! From the mechanism to the float, screws, and special tool for tightening the mechanism on the toilet bowl!

The mechanism works as it should. My only complaint is that it doesn't screw on the same turns as the old Spek, and I had to completely unscrew the tank and replace the old mechanism entirely.
