If there is a requirement to reroute the sewage from defective piping by bypassing the defective location and letting the sewage flow back into the pipeline behind this location, then bypass bags are the suitable solution due to their largest possible through- flow opening. Only three bypass bags are required for pipe diameters from 100 mm to 1,200 mm (4 inch to 48 inch). The outside thread enables the connection coupling to be freely selectable.
With the sizes PDK 10/20 and PDK 20/50 the bypass adapters are fitted on the PE core with screws. With bypass bags PDK 50/80 and PDK 50/120, the ducts (also with outside threads) are directly in the PE core. If required, a throughflow opening of up to 8″ can be supplied for both sizes.
- Standard test counter- pressure of 5 m WC (7.25 psi)
