Dear Valued Customer,
We sincerely apologize for the difficulties you went through trying to install the pop-up drains. We would like to better understand where in the installation instructions did it become complicated for you. If you don't mind, please send that information to jessp@vigoindustries.com. The nut should never be difficult to turn until you make the final quarter turn. As for the leaks, the pop-up drain is designed to be installed as is out of the box and should not leak. Please send all the details over so we can work on resolving the issues.
Regards,
Vigo Product Support
