The 4" Pond Bottom Drain is essential for maintaining a clean and healthy pond with a gravity-fed filter system. Strategically positioned on the pond floor, it efficiently removes water and debris, ensuring optimal water quality.

The drain setup includes a sump, which is seamlessly integrated into the pond base, and a dome that covers it. For liner-based ponds, the sump comes with a flange ring to create a watertight seal. In concrete ponds, the flange ring is unnecessary. The gap between the sump top and the dome typically ranges from 2 to 5 cm to prevent smaller fish from entering the filter system.

Designed for efficiency, bottom drains can handle larger solids, making them less prone to blockages compared to submerged pond pumps. Installing multiple drains eliminates sludge accumulation, contributing to a cleaner pond environment. Additionally, the absence of visible hoses and power cables enhances the pond’s aesthetics.

For optimal performance, the connecting pipe-work should run as directly as possible, with large curved radius bends to maintain maximum flow-rate and minimise debris build-up.

• Efficiently manages water and waste removal
• Suitable for both liner and concrete ponds
• Prevents smaller fish from entering the filter system
• Handles larger solids to reduce blockages
