Replacement Intake Filter for TidalWave2 The Atlantic Water Gardens Waterfall Pump 3700 screen is the replacement intake filter for the TidalWave2 TW3700 waterfall pump, rated at 3,700 GPH (14,007 LPH). At this flow rate, the intake screen works under significant suction, making it more critical — and more prone to accelerated wear — than the screens on lower-flow models. High-Flow Screens Demand Regular Inspection The TW3700 moves over 14,000 litres per hour through a relatively compact intake opening, creating strong suction force across the screen material. Debris is held tightly against the screen under this suction, making it harder to clean and more likely to cause fatigue cracking over time. Inspect this screen at every cleaning — quarterly during the active pond season and again at spring startup. Replace at the first sign of cracking or warping to keep the TW3700 delivering full rated output.
