21 Inch Pro Series Water Heater Pan with PVC Adapter

The 21 Inch Pro Series Water Heater Pan with PVC Adapter is a compact Pro Series pan intended for residential water heater installations where a drainable safety pan is needed but space is limited. It provides a slightly larger working diameter than a 20-inch pan while retaining a smaller footprint than larger utility-room pans.

This 21-inch model is best used when tank diameter and closet clearance need to be balanced carefully. The included PVC adapter supports drain-line connection so incidental water can be directed away from the water heater base.

Product Features:

• 21-Inch Pro-Series Opening: Sized for compact replacement jobs where a 20-inch aluminum pan is too tight but a 23-inch pan is oversized.
• PVC Adapter Included: The adapter gives the installer a ready-made transition from pan wall to drain piping.
• Installer-Focused Upgrade: Pro-series pans are typically chosen during tank replacement to satisfy code or warranty-adjacent installation practices.
• Smaller Closet Footprint: The 21-inch size helps when the water heater sits in a narrow closet, alcove, or laundry-room corner.
• Overflow Routing Purpose: The adapter lets collected water exit the pan rather than remaining underneath the water heater.
• Base-Diameter Buffer: Provides a modest clearance margin around compatible tank bases for easier placement.
• Replacement-Friendly Form Factor: Useful when the old pan is cracked, corroded, missing, or too small for the new tank.
