Contaminated Waste Drain
Oil and water that can accumulate on the top pan is disposed of through the contaminated waste
drain. This oil and water mixture is considered contaminated and disposal must comply with
local, regional and national codes. The volume of waste will be minimal and can be collected in a
container of some appropriate type.

2.6 Flow Requirements
Figure 2-4, Pressure Drop Values, illustrates the pressure drop for four different pipe sizes. The
graph can be used to calculate the minimum source water pressure.
1. Enter the graph at the required GPM and note the pressure drop figures for the different
pipe sizes.
2. Multiply the pressure drop (PSI/FT) by the length in feet of each pipe size used from the
water source to the intensifier. Add the values together for a total pressure drop value.
