• ## How to size Water Pipes for Pluing Installations

Conversely a steeper grade requires a smaller pipe size for the same flow. A slope or grade can be defined by a horizontal length and a vertical drop. For example 1 in 100 (or 1:100) means 1 measurement unit vertical to 100 same measurement units horizontal. Therefore to start calculating pipe sizes we must first find a length and a vertical drop
