   Course Description:

This is an online, interactive Short-Course that teaches the student how to perform the DC test procedure. Using illustrations and animations, this course presents the student with a schematic view of a DC assembly and guides the student, step by step, through the two DC tests. These tests include:

  • Test 1 – Check Valve 1 Tightness
  • Test 2 – Check Valve 2 Tightness

Following the procedure, the student is presented with two troubleshooting scenarios:

  • Troubleshooting Leaking Shutoff Valve: Continuous Test Cock 3 Discharge
  • Troubleshooting Leaking Shutoff Valve: DC Test 2

After the troubleshooting section, there are two simulations. The simulations allow the student to perform the procedure repeatedly to reinforce the information taught in the first section.
This is an easy, comfortable presentation of the DC test procedure which strictly adheres to the technical testing standards.

   Course Features:
  • Interactive Macromedia Flash animations that guide the student through the procedure and allow the student to practice the DC test procedure.
  • Synchronized audio reinforces the text.
  • Self Check quiz questions challenge the student to demonstrate their knowledge
  • Print version of the DC test procedure that the student can use to follow along and make notes.
   Who Can Benefit:

Students who can benefit from this course are anyone who needs to prepare for their certification or recertification test and does not regularly perform the DC test procedure. Additionally, anyone who supervises backflow testers and needs to understand the basics of the DC test procedure. Finally, anyone who has been away from the field and is looking for a refresher on the DC test procedure would benefit.

   Prerequisites:

To successfully complete this course, the student should have a basic understanding of roles and responsibilities of backflow testers. They should be familiar with backflow test equipment and how it is used.

   Skills Gained:

Upon completion of this course, students should be able to:

  • Identify the basic components of an DC valve assembly
  • Describe the purpose of the DC valve test procedure
  • Describe check valve 1 pass/fail requirement
  • Describe check valve 2 pass/fail requirement
  • Perform check valve 1 test
  • Perform check valve 2 test
  • Troubleshoot common problems
