Buying Guide
What to consider when choosing a water heater catch pan
- Pan diameter and depth: Ensure the pan footprint matches or exceeds your heater base and the depth accommodates expected water buildup.
- Material: Plastic pans resist rust and are lightweight; aluminum pans offer durability in tougher environments; select based on space and corrosion risk.
- Drain fittings: Look for supplied fittings or adapters that match your drainage system’s pipe size (commonly 1″ to 1-1/2″).
- Installation space: Check side openings or pre-cut features for easy hose routing, especially in tight utility closets.
- Maintenance: Consider pans with smooth interiors and drainage covers to minimize clogs and simplify cleaning.
- Compatibility: Confirm compatibility with electric or gas water heaters, and verify clearance around valves and exhausts.
