STEMAR WASTE WATER BYPASS /

FULL FLOW-THRU SEWER PLUG

 

Stemar’s Wastewater Bypass is an approved method of diverting live sewer lines while repairing or adding to existing manholes.

Stemar’s Bypass uses gravity with no need for pumps or other expensive machinery. A standard Stemar Bypass has minimal flow reduction. The amount of flow reduction is normally only one pipe size. Wastewater from a 12" (300mm) pipe could be diverted through 10" (250mm) Flex-Hose (heavy duty flexible bypass hose).

Stemar’s Bypass Head (Full Flow-Thru Plug) has an inflatable sleeve and is multi-sized. The Bypass Head is normally designed for use in two or more sizes of pipe. The Bypass Head is galvanized steel with an inflatable sleeve made of black neoprene rubber reinforced with one or more layers of tire cord.

Stemar’s Bypass Head is attached to our Flex-Hose with high torque, stainless steel pipe clamps. Another multi-sized Bypass Head can be attached to the downstream side of the Flex-Hose to completely seal both sides of the manhole. Stemar’s Bypass can accommodate one to several additional lateral connections, if needed.

Stemar’s Flex-Hose is a rubber coated, heavy duty, nylon hose with an enclosed steel helix coil. This design allows the user to shorten and/or bend a 9’ (2700mm) length of Flex-Hose to approximately ½ its length, without losing its shape. Stemar’s Bypass normally comes with 9’ (2700mm) of Flex-Hose. Standard Flex-Hose lengths are: 1’ (300mm), 2’ (600mm), 5’ (1500mm), 9’ (2700mm), and 25’ (6300mm). The Flex-Hose can be coupled together for almost any length or configuration. Standard Flex-Hose internal diameters: 2" (50mm), 4" (100mm), 6" (150mm), 8" (200mm), 10" (250mm), 12" (300MM), 14" (350MM), 18" (450MM), and 24" (600mm).

Stemar’s Flow-Thru Pipe (Light Weight Bypass Pipe) is attached to Stemar’s Bypass Head by bolted flange and is used on Stemar’s larger Bypass’ when a larger flow-thru is needed. Standard Flow-Thru Pipe lengths are 2’ (600mm), 3’ (900mm), 4’ (1200mm), and 5’ (1500mm). Stemar’s Flow-thru Pipe can be flanged together for longer lengths. Standard Flow-Thru Pipe diameters: 27" (700mm), 34" (860mm), 42" (1100mm), and 48" (1200mm).

Stemar’s Bypass comes standard with 5’ to 25’ (1500mm to 6300mm) of inflation hose inside a hollow braid polypro rope. This is attached to the Bypass Head on one end and on the other end is a 5/16" (8mm) safety hook. The hose comes with a standard air tank valve for inflating. This polypro rope/inflation line is used for lifting and lowering smaller Stemar Bypass’ as well as for inflation. The Larger Stemar Bypass’ come with nylon web slings for lifting and lowering.

OPTIONS INCLUDE:
