THE HEIGHT CONTROL IS POSSIBLE DOUBLE TRAP STRATIFORM PLUMBING FIXTURES

摘要

The present invention relates to an layered piping device of a double trap collecting sewage drawn from a drainage trap on the bottom, a washstand, and a bath by being installed on the upper part of a slab on a floor and simultaneously discharging the same. The trap is formed on the main drainpipe side discharging the sewage to the outside in order to completely block odor drawn from the outside with or without the existing washstand and the trap installed in the drainage trap. The layered piping device of the double trap can control a height in order to provide convenience of installation by enabling the location and the height of the drainage trap to move.
