Drain preparation
The type of drain installation required depends on the answers to the following questions:
• Do local codes or ordinances require an air gap?
• Will the waste tee or garbage disposal connection be less than 18 in. (45.72 cm) above the floor?
• Will installation have a drain loop less than 32 in. (81.28 cm) above the floor?
If the answer to ANY of these questions is YES, Method 1 MUST be used. Otherwise either Method 1 or

Install the waste tee or garbage disposal connection and air gap according to manufacturer’s instructions.
Method 1 - Air gap with a waste tee or garbage disposal connection
Method 2 - High drain with a waste tee or garbage disposal connection

connected to a waste tee or garbage disposal lower
than 18 in. 45.72 cm) above the floor.
