Notes: For a hassle-free installation, note that only the wall-threading pipe needs pre-embedding. The guide rod and lifting rod effortlessly attach to the pond wall using expansion bolts, eliminating the need for any pre-embedded parts. However, pre-embedded parts and flap valves should be procured and installed by the users. Additionally, users have the flexibility to choose between horizontal or vertical installation of the reflux pump, based on their specific requirements.
