Notes: For optimal installation, while the wall-threading pipe needs pre-embedding, the guide and lifting rods attach securely to the pond wall using expansion bolts, eliminating the need for pre-embedded parts. Users are responsible for purchasing and installing pre-embedded components and flap valves. Additionally, choose between versatile horizontal or vertical installation for the reflux pump, tailored to your needs.
