An efficient flushing siphon bag which fits any gulley hole and requires no mains connection for automatic drainage comprises a closed, bag-like outer skin (1) and a siphon tube (2) which rises from the base and is mounted so that it first slopes upward above the bag to a certain height and then slopes downward. The siphon bag is filled through a connection (3) to which it is attached by means of loops, eyes (4) or the like. The outer skin (1) and the siphon bag (2) are made from a waterproof, tear-resistant mobile woven fabric. |
