The invention relates to a device for the checking the tightness of a sanitary installation, wherein a fitting body is connected with connection lines, the terminate in openings at the top of the fitting body all, the apparatus is sealingly mounted on the upper side of the fitting body instead of a fitting.

raw installation water pipes in sanitary compartments are used for the flush-mounting wall housing, the first serve to, receive a fitting body, with connection lines, output lines is connected to water outlets or the like after completion of the installation a sanitary fitting [...] receive and, as soon as the conditions are satisfied on the wall side. A closes the wall installation housing cover plate to be mounted with the sanitary fitting can be connected with four connection lines. Typically, the fitting body, are arranged so that four openings Squared on its upper side.

The installation must be tested for leakage before the attachment of the sanitary fitting. For this purpose are in use so-called hydraulic pressure controllers , are connected to the fitting body is arranged in the flush-mounting wall housing, so that conductors or. Portions thereof can be put under pressure, and any leaks are detected before completion. Examples of such devices 20 2011,050,690 oneself in DE, in DE 19,856,157 10 2011,000,807 or in DE.

The common problem for all known hydraulic pressure controllers then lies therein that always only two adjacent openings can be connected, so that not every flow constellation can be directly examined, for example from a first opening to the third of four. Another disadvantage is that after each testing process the device dismounted, twisted and must be mounted again, since no "disconnecting" is provided when the cradle is mounted device.

The invention has made it now proceed to the task, to improve this situation and to simplify and to accelerate considerably the proof test.

according to invention is therefore provided that the device comprises an obturating block, in the underside of which a flow connection is formed between all the openings in the upper side of the fitting body.

Unlike the known hydraulic pressure controllers is possible for the first time in this way a flow between all connection lines. The annular channel formed by a downwardly open is here preferably flow connection, which extends around a central connecting bolt. If now not only the tightness of the entire connection lines is to be verified, but the tightness of individual flow paths between each aperture and the second and/or third opening, so are preferably Stopper provided, the unneeded openings are used in the seal, and said terminal line (s). The obturating block has in a preferred embodiment, a receptacle or bore for the plug in the fitting body on per opening. In another preferred embodiment is provided that the sealing plug is adjustable from outside in its housing. In particular, the sealing plug is in the receptacle or on a. Bore rotatable valve spindle arranged.

Thus is increasing the opening in the fitting body in the manner of a valve close and open again, without the obturating block must be removed, since each sealing plug is withdrawn into the annular passage in the open position.

Since four valve stems are provided preferably in the obturating block individually adjustable, the recoverable assembly advantagestime gained at such a still and execution are becoming increasingly apparent.

In a simplified construction, the sealing plug can also be inserted into the receptacles in the annular channel, wherein for removal or. Displacement of the sealing plug is dissolved and said obturating block mounted again. In this embodiment the flow connection between all openings But it is also possible and any flow paths are selectable.

It is additionally of advantage in both speech, when on the underside of the closing block projects for engagement in a recess of the fitting body a pin-shaped positioning aid. These closes and the handling facilitated of the closing block from intermediate positions.

The invention is now described on the basis of the Figures of the attached Hereinafter closer Drawing, without being reduced to thereon. It show:

A Flush-mounting wall housing for sanitary installation elements 1 connected to the bottom part 1 and a base or bottom part 2 faces on a side wall, and is open on the front side 4. The Flush-mounting wall housing can have any suitable form, preferably at least the front portion of the side wall is formed as a hollow cylinder 2. A 25 and a thereto after the completion of the fitting body comprises a sanitary Installation element [...]production work to be mounted, not-shown Sanitary fitting, wherein a cover plate covers the wall installation housing. The cover plate is selected adapted of the sanitary fitting. The Sanitary fitting can, for example, a single-lever mixer with and without conversion, a thermostat, a [...] , etc. be.

The Flush-mounting wall housing is 5 provided with passage openings, 25 are connected by the leads to the fitting body.

Four passage openings 5 are arranged on cross Prefers, wherein, for example, cold and hot water line by the left and the opposite right passage opening through the upper and lower passage opening lines to [...]. tub connections can be guided. In the fitting body and enter the four terminals 25 in openings 26 are deflected at the front from parallel. In 25 to be connected to the fitting body are made then the corresponding connections between the lines sanitary fitting.

[...]raw assembly Throughout the up to completion of said 4 is a cover or closure of the front side a whole works advantageously of the flush, 26 and of the openings 25 of the fitting body so as to avoid pollution. It is therefore common practice, the apparatus for leak testing as accessories to each spanning Flush-mounting wall housing, and provide not only for the leak test, but already in the construction stage as a housing cover. The device is connected with the fitting body, as early as possible therefore 25. The apparatus has an obturating block 30 on, the forms is designed in adaptation to the shape of the wall installation housing and a cylindrical insert part in the embodiment shown. As Fig. 4 can be seen, the obturating block 35 in the front region 30 is also hollow and closed by a lid. After without its lid 29 is a centrally located screw 35 accessible and by means of a tool, in particular a rotatable allen key , wherein the screw 28 29 25 serves for fixing within the central bore of the fitting body. The Allen key can be packed after removal of the lid 30 and the closing block 25 are available.
