How to Install a Drain in a Granite Bathroom Sink

Installing a drain is an easy process and should not require the aid of a professional plumber. Even installing a drain system in a sink made of granite is as simple as following instructions and having the right tools. Since drains are made in a uniform fashion, any drain made for a bathroom sink will do. Special orders can be made so that the pop-up stopper resembles the granite of the bathroom sink. These special order drains may also come with washers made of different material, but the regular rubber and cardboard washers will be sufficient if used.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Drain kit
• Plumbers putty
• Water pump pliers

Installation

1. Remove the drain kit from the package and lay the parts out on the floor. Locate each part and separate them so that they are easily recognizable.

2. Locate the top flange. Roll some of the plumber’s putty into a small rope long enough to reach around the circumference of the flange ring and press into place.

3. Insert the top flange into the sink. Locate the washer and nut that screws onto the top flange from under the sink and tighten the nut with your hand.

4. Insert the pop-up stopper into the drain and locate the parts that operate the pop-up; the pivot seat and gasket, the horizontal rod and the nut that holds it all in place.

5. Line up the rod with the pop-up stopper after threading it through the pivot seat and gasket. Tighten in place with the nut provided. Snug all parts in place with water pump pliers and clean excess putty off the top flange. Connect drain pipes accordingly.

Tips & Warnings

• Plumbers putty is recommended over the rubber washer because of durability. This is only an option; the rubber gasket can be used if preferred.
• Use care when applying pressure with water pump pliers as they can damage plastic threads.
