Weipike Siphonic Drainage System

Rainwater Hopper

Weipike rainwater inlets precisely maintain a stable and controllable water depth at the inlet, enabling the system to operate in a stable siphon state. This effectively controls roof water loads, ensuring safety in compliance with the “Technical Specifications for Siphon-Type Roof Rainwater Drainage Systems,” and provides detailed hydraulic calculation reports for the system.

Fastening System

The Weipike rainwater pipe mounting system consists of square steel guide rails running parallel to the pipes, pipe clamps connecting the pipes to the guide rails, hangers for securing the guide rails, and galvanized angle iron.

Short Eccentric Reducer

By using atmospheric pressure to convey rainwater collected by downspouts located far from the vertical pipe through horizontally laid horizontal pipes to the top of the vertical pipe, this fundamental problem is solved, and the many advantages of siphon drainage become apparent.

HDPE Pipe

The Weipike siphon rainwater inlet bowl separates air from water, creating full-pipe flow conditions within the pipe even when the water level in front of the bowl is very shallow.

Double Flange Coupling

By utilizing atmospheric pressure to transport rainwater collected in catch basins located far from the vertical riser through horizontally laid horizontal pipes to the top of the vertical riser, this fundamental problem is solved, revealing the many advantages of siphon drainage.
