This course was created to give the Oregon plumber 8 hours of continuing education on code related review topics. We’ve organized our class into four main areas:

  • The reopening of buildings after prolonged disuse
  • Residential water heaters
  • Sanitary drainage systems, and
  • Graywater and private onsite wastewater treatment systems

The course begins with the topic of reopening buildings after prolonged disuse, taking an in-depth look into the common problem of today. We examine the issue at hand, the strategy for solving it, the dangers lying in stagnant water, and the individual steps for reopening a building that has been in a state of disuse. The lesson ends with a look to the future, with an emphasis on preventing these issues as we move forward.

From there, we go over the topic of residential water heaters. We start with the different types of water heaters available, and then move into the codes and standards that typically govern these types of heaters. We look at a variety of subtopics in this lesson, including water heater sizing, temperature maintenance, hydronic heating, “green” water heater systems, and best practices.

Next up is our lesson on sanitary drainage systems. We start with the basics, going over backflow and sewer gases, and the many components of a sanitary system, such as cleanouts and ejectors. We also go over installation, codes, standards, technical considerations, and grease interceptors.

Our final lesson will focus on graywater (or greywater, depending on where you’re from). We begin with the principles of graywater, and continue with the design and installation of graywater systems and best practices. The final half of this lesson is devoted to private onsite wastewater treatment systems (or POWTS), going over the basics and finishing with design and installation.

Throughout the course are in-text questions designed to test your knowledge as you go. Once you’re finished, you’ll have completed eight of the required hours for renewing your license, all at your own pace!
