Syfi consists of three main parts, easily assembled (as shown in the image).
A box-shaped body, a plug with an upper inlet (liftable for inspections and maintenance) and a tile whose shape adapts itself to siphon contours.
In the sequence below is represented:
tile insertion inside box-shaped body phase (Figs. from 1 to 3) and the subsequent rain downpipe plug with inlet closing (Fig. 4).
Each Syfi is provided with two seals for box-shaped body better sealing.
One positioned between box-shaped body and upper plug and one at the lower box-shaped body inlet, where rain downpipe is inserted.
