Hello All I have a question about piping for CCTV network and coaxial cables. I don't know if its related to this category or not. I've heard that pipe channels between two hand-holes must have a 3% slope. I searched the web very much but I did not find something good. Do you know is it a requirement for CCTV piping? and if true why is it? Best regards

Thank you myiicu, So, Is there any documents of all standards & requirements about CCTV Excavation , anywhere on web that I could refer it formally and I could use it at my company? I want to have a guide for Excavation, Piping, connections, hand-holes , distance between hand-holes,.... It would be really appreciated if you help me
