A run-off outlet being a part of the drain or drain trap mounted in the holes of the sanitary devices, having a socket designed most often for closure, which is a part of the run-off neck bushing, characterised in that it has a space in the run-off bushing (1), under the socket (2), and support for a removable volumetric stariner (4), which is not joined with closure (3) and whose height is at least 2 cm. In such a way, in the described run-off outlet there is mounted a volumetric strainer independent of the closure. Over the space designed for the strainer, there could be placed a removable separtor (5). The strainer could have a grip facilitating its removal. The strainer should have a design matching the run-off outlet. The strainer could have a grip enabling its fastening in the run-off bush.
