Method for producing a filter bottom for water treatment

Apparatus for setting in position and securing, on the floor of a filter, members providing for fluid to flow through the floor. The apparatus consists of a support arranged so as to receive the member, such as a nozzle or equivalent, introduced inside a housing created in shuttering used for making the filter floor. The housing and the support are configured to removably secure mechanically, for example by a snap-in action, the support in its housing.
