摘要
The ventilation has a guttering pipe connected in the lower part with a connecting piece (6) and in the top with a connecting piece (5). The connecting pieces are again connected with one another by an air supply pipe (3). The connecting piece (6) is attached in the upper third of the waste water pipe (8). The connecting piece (6) can be attached also at the lower end the gutter-pipe (9) or at the joint, which connects the gutter-pipe (9) with the waste water pipe. The connecting piece (6) has for example to the waste water pipe (8) a three-way cross section, on the air supply pipe side (3). The ventilation is manufactured from PVC or a similar plastic, or cast iron.
