4Natural Stone Farmhouse Sink Installation Instructions
Apply a bead of silicone sealant to the base of the 
strainer flange and place the flange in the drain 
opening in the sink.
If your drain has a disposer flange, use the 
directions supplied with the garbage disposer to 
attach the disposer and complete your installation. 
For drains with strainer baskets, slide the rubber 
gasket and friction washer up the strainer flange to 
the bottom of the sink.
Thread the lock nut onto the drain assembly. 
Hand-tighten and make sure that the drain is 
properly aligned. When ready, finish tightening with 
a basin wrench to secure the drain. Secure the 
P-trap to the strainer flange with the provided 
compression nut and ferrule.
