<p>The valve arrangement (1) has a water channel (15) which runs in two housing pieces (10a,10b). A connection (37) is provided between the both housing pieces. The arrangement has a non-return valve (14) in the former housing piece and a controllable valve (7) in the latter housing piece. The connection is locked with a locking element which co-operates with the non-return valve. The connection is unsolvable with opened non-return valve and is solvable with closed non-return valve. An independent claim is included for a flushing device with an operating unit.</p> |
