         10 . The sanitary insert part ( 1 ) as claimed in  claim 7 , wherein the base structure comprises an upper part ( 13 ) and a lower part ( 14 ), and a seal element ( 7 ) is provided on the upper part ( 13 ) of the base structure ( 12 ) and the securing means ( 4 ) is provided on the lower part ( 14 ) of the base structure ( 12 ), and a snap-in connection connects the upper part ( 13 ) with the lower part ( 14 ). 
     
     
         11 . The sanitary insert part ( 1 ) as claimed in  claim 1 , wherein the at least one discharge opening ( 10 ) located at a distance from the securing means ( 4 ). 
     
     
         12 . The sanitary insert part ( 1 ) as claimed in  claim 1 , further comprising a collection chamber ( 15 ) formed between the securing means ( 4 ) and the outlet side ( 3 ), through which excess water escaping through a leachate path ( 20 ) between the securing means ( 4 ) and the counter securing means ( 6 ) is collected. 
     
     
         13 . The sanitary insert part ( 1 ) as in  claim 12 , further comprising a lip seal ( 17 ) on the outlet side ( 3 ), that seals the collection chamber ( 15 ) in the water outlet ( 5 ) to the outside. 
     
     
         14 . The sanitary insert part ( 1 ) as claimed in  claim 1 , wherein the securing means ( 4 ) comprises a thread connection, and the counter securing means is adapted to be a counter thread connection that is adapted to allow the insert part to be attached to a water outlet ( 5 ) on a sanitary fitting. 
     
     
         15 . The sanitary insert part ( 1 ) as claimed in  claim 1 , further comprising a tool attachment ( 18 ) formed in the outlet side ( 3 ) that is adapted to assist in at least one of an attachment or detachment process.
