Thank you for contacting Jetta! 


We are happy to help.  


Jetta's Toe Tap drains for our drop-in and skirted units have an adjustment screw. To find the adjustment screw, simply take the stopper out (not the full drain assembly) and flip it over. 


To adjust the length of the screw, twist the hexagon plastic piece left or right with pressure.


For a tighter close, if your drain is losing water, please turn to the left to shorten the screw.


If the drain is not staying closed, please turn to the right to lengthen the screw.


Replacement parts please see the link below.
