The invention relates to a drain valve () for a sanitary cistern, in particular a concealed cistern, having a valve housing () with a drain opening (), the drain opening () being delimited by a valve seat (), and a valve body (), which rests in a sealing manner on the valve seat () in the closed state of the drain valve, the valve housing () having a housing chamber (), arranged upstream of the valve seat () in the direction of flow, for receiving water. To allow the drain valve to be arranged outside the cistern and to enable access to the drain valve for maintenance as well as removal via an inspection opening that can be covered by a toilet bowl or urinal bowl, the invention suggests that the valve body () is provided with an auxiliary chamber () for receiving water, the receiving volume of which is smaller for water in the open state of the drain valve () than in the closed state of the drain valve (), the auxiliary chamber () being delimited by a flexible and/or movable wall section, and wherein the auxiliary chamber () is associated with an auxiliary drain valve () which in a first position permits an inflow of water into the auxiliary chamber () and in a second position permits an outflow of water out of the auxiliary chamber ().

Drain valve for a sanitary cistern

A drain for a wet room, in particular for a shower, includes a drain housing at which an outlet for connecting a drain pipe. In order for a drain of this type to offer a higher drainage capacity in the case of a given drain pipe of standard diameter, the drain housing has a pump for conveying water towards the outlet. The pump is provided with a hydraulic drive. The wet room, in particular a shower, includes a water supply line and a drain of the above-mentioned type.

Drain, in particular shower drain

The invention relates to a drain ('), in particular for floor level showers, the drain comprising a pot shaped drain housing () including a shell or pot shaped base component () without a pipe connection, a laterally disposed pipe connection () and an inlet opening () at a top side of the base component, and an immersion pipe () which is insertable into the drain housing through the inlet opening () and defines a stench trap with the drain housing. In order to be able to adapt such a drain to various installation conditions in a flexible manner, so that the installation height, water lock height and drain output of the drain is variable, the invention provides a solution wherein the base component () is connected in an elevation-adjustable and liquid-tight manner with the drain housing ().
