Plumbing: what are the slopes required to be maintained for 50 mm, 75 mm,100 mm, 150 mm & 200 mm pipes?

As per UPC. ,2012Ediition

Table 704.1

THE SLOP RTEQUIERD FOR HORIZONTAL DRAINAGE PIPE IS AS FOLLOW:

1 -     21/2'' PIPE & LESS                    

   1/4 SLOP INCH/FOOT

2 -     3'' : 6 '' '' PIPE                                   1/8 SLOP INCH/FOOT

3 -     8'' & LARGER  PIPE & LESS        1/16 SLOP INCH/FOOT

1:150

In practicality at site we have coordination with other systems for the palcing of pipe runs and as per ground reality it is normally maintained 1:100.

only 1% to 50mm, 75mm, 100mm, 150mm & 200mm because if your slope is above 1% you will be conflict to other trades installation.

50 mm = 1:50 slope ratio

75mm = 1:50 slope ratio

100mm = 1:60 slope ratio

150mm = 1:100 slope ratio

200mm = 1:120 slope ratio

slopes area as follows

pipe size                          slope

50mm                                1:40

75mm                                1:50

100mm                              1:60

150mm                              1:90

200mm                              1:120
