- Description AquaSure Large Bottom Drain & Rubber Membrane Aerator Dome Assembly The AQUA SURE Large Bottom Drain and Rubber Membrane Aerated Dome Assembly is engineered to provide a high-efficiency, low-maintenance solution for pond construction. It combines a high-performance bottom drain with an integrated aeration dome, ensuring both superior debris removal and enhanced water oxygenation. The aerator on this dome features a precision-perforated rubber membrane, a trusted choice among koi and pond enthusiasts for over a decade. Designed for efficiency and discretion, the membrane sits unobtrusively at the pond floor while delivering reliable, long-lasting aeration By drawing debris and solids directly from the pond floor, the system maintains excellent water quality and prevents waste from breaking down into fine particles. The addition of the Rubber Membrane aeration dome delivers exceptional aeration and circulation, creating a healthier pond environment. The rising air bubbles generated by the diffuser increase water movement, channeling waste towards the bottom drain and making it up to 30% more efficient at removing debris. At the same time, the system improves oxygen levels—benefiting both fish and overall pond health. Aerated Dome Specifications Diameter: 380 mm Diffuser : precision-perforated rubber membrane Air Line: Includes 10 m × 6 mm ID air tube Recommended Air Pump Size: 40-60 LPM Installation and Placement Bottom drains are positioned on the pond floor, ideally in the deepest area(s). Each drain consists of a sump set into the pond base and connected to pipework. Multiple drains may be installed in larger ponds to eliminate dead zones and prevent sludge accumulation. As gravity-fed pipework is typically laid beneath the pond and encased in concrete, bottom drains should be planned and installed during pond construction. For use with 110mm Solvent weld pipe (4″ waste) Performance Advantages More efficient than internal pond pumps, which are prone to clogging. Handles larger solids without blockages or reduced flow. Provides consistent debris removal for cleaner, healthier water. Construction Details The sump is supplied with a flange ring, which secures to the top lip. In liner-based ponds, the liner should be sandwiched between the flange ring and sump lip, sealed with a non-toxic adhesive for a watertight bond. In concrete ponds, the flange ring is not required. The sump should be set flush with the pond’s final rendered surface. A dome, positioned 2–5 cm above the sump, prevents smaller fish from entering the filtration system while ensuring maximum flow. The Bottom Drain and Dome Kit includes: Bottom drain sump Flanged ring Stainless steel screws Rubber Membrane Aerated Dome Height adjustor tube 10 Meters of Clear PVC airline (6mmID) Pipework Recommendations For maximum efficiency and reduced debris buildup: Run pipework as directly as possible. Where bends are unavoidable, use wide-radius curves to minimize flow resistance and maintain consistent performance. Pressure or Waste Solvent Weld Pipe? If your application requires 4″ pressure pipe (114.3mm), eco-filtration stocks a wide range of reducing and joining bushes to suit your needs. We supply a 110mm–114.3mm reducing socket, specifically designed to convert a standard 4″ waste (110mm) Bottom Drain Sump socket for use with 4″ pressure pipe (114.3mm).
