Thank you for contacting Jetta!
We wanted to let you know that starting with our 2022 Walk-In tubs, the drain design no longer includes an adjustment screw for modifying the height of the drain stem below the drain cap.
However, you can achieve a tighter seal by gently filing down the steel stem to the desired height. We recommend doing this gradually while testing the fit to ensure the best seal.
For additional support, please reach out to sales@jettacorp.com.
Thank you for choosing Jetta!
