cameroon gce advanced level water supply and drainage networks processes 3
I- PRESENTATION :
For the installation of a kitchen, you are requested to install a kitchen sink as indicated on the execution plan of page 3.
– The cold water distribution network is in PVC pressure pipe of nominal diameter 25mm. The supply pipe
starts from the riser coming from the lower floors.
– The domestic hot water distribution network is in Alu- plastic compression pipe of ϕ 16mm. The hot
water pipe starts from an electric hot water pipe which is located at the lower floor levels.
