Why Danco Overflow Plate Gasket Is Necessary
I’ve found that a Danco overflow plate gasket is necessary because it helps create a tight seal behind the overflow plate, which keeps water from leaking into the wall area.

My experience has shown me that this little part also helps improve the overall performance of the tub or sink drain system. It gives the overflow plate a better fit, reduces dripping, and helps prevent annoying leaks that can waste water and create mold or mildew problems.
I like that it’s a simple, low-cost fix, but it makes a big difference. For me, using the gasket is an easy way to protect my bathroom from water damage and avoid bigger repair issues later.
