PLUVIKIT system


Rainwater collection system
Calculation of rainfall for framing roofs
Input
S : roof surface
S = 40m2
H: rain intensity
H = 75mm/h
It will calculate the amount of water to be collected
V : volume of water to be collected
V = 40 x 75 : 3600 = 0.83 litri/sec
V = 0.83 litri/sec    This value will determine the main criterion for choosing the entire collection, from gutters and downspouts and then channel up homes to the sewage collector

Table A
The choice of diameter and number of pipes to be installed in accordance with the maximum level of water ice on the surface to be evacuated collection reported.

Table B                                                                                                                                                     Choice section and tilt system on the surface of the roof gutters reported as
Check gutters and downpipes are compatible results

Gutter assembling

1.Adhesive application

  • 1.Cut the profile to the desired  length using a normal metal saw and remove rough parts with sandpaper
  • 2.Clean the surface to be glued using a detergent for PVC
  • 3.Apply the glue using or directly from the tube on the extremity of the gutter and at the joint or stopend cap.
  • 4.Join within two minutes and hold in place for a few seconds allowing the glue to set
  • 5.After 24 hours test the holdfor the glue.
2.Gasket mounting
