System Sampling Procedures
1.
Sampling can be done quickly and in a single day. Ensure there is an electrical outlet onsite with appropriate
amount of extension cord for your wet-dry vac. For best outcome, you want your wet-dry vac as close as
possible to the Sampling Tube Storage Pipe.
2.
Ensure your Collection Flask is clean and ready to receive a sample. One Collection Flask per System
Sampling Port
3.
Open the Sampling Tube Storage Pipe and remove the Sampling Tube. Each System Sampling Port will be
sampled individually.
