Commercial Plumbing Course Developer

Hello, I'm Jaden. My experience includes nearly 20 years as a consulting engineer in the roles of project management, private consulting, and Principal. Also, I've worked as a licensed Mechanical/Plumbing Engineer for over 10 years.

I'll be your personal coach so you won't be alone in your studies. Scroll down below to see actual coaching conversations where I answered questions to help students understand the material.

I have a question on how to utilize the tables to find the sizes with development length or others. For example, looking up in table 4.02 IFGC 2021 to find Capacity for schedule 40 metallic pipe 1.25" with a run of 156 feet (2psi, 0.6 SG, 0.5 wc), I found 156ft lies between 150ft and 175ft. Should I go for whichever is higher or lower? should this be applied to all tables that have the conditions stay in between numbers?

If your length is 156-ft, you need to read the entry for 175-ft. The higher value.

Think about the the values in the left column as “the pipe system can be size for anything up to and including” these values. When you go over (156 bring more than 150) you read values from the next row. In this case, that is the 175-ft row.

thanks Jaden!

I need help understanding Table 906.1

The question is: "What is the minimum size of stack vent required for a 6-inch waste stack draining 1,200 drainage fixture units, which has 172 feet of developed length?"

Answer 1: 4-inch Answer 2: 5-inch Answer 3: 6-inch Answer 4: 3-inch

The correct answer is: Answer 2.

Raymond,

This is a busy table, no doubt. Let's take it one piece at a time.

The question is asked in relation to a 6-inch waste stack. Start on the LH side of the table and read down the column titled "Diameter of Soil or Waste Stack (inches)". Stop at the row listed as 6. It doesn't indicate units in the rows, only in the Column title. But this is the row for 6-inch soil/waste stacks.

Now, back to the question. We are looking for the choice that is appropriate for a total of 1,200 drainage fixture units (dfu). There are (3) sub-rows in the 6-inch row. One for up-to 500 dfu, one for up-to 1,100 dfu, and one for up-to 2,000 dfu. This is the first tricky part. A dfu count of 1,200, is more than the first two choices: 500 and 1,100 respectively. Neither of those rows can be used. But 1,200 is under the 2,000 dfu maximum of the 3rd row. This is the correct choice.

The final part of the question identifies that the developed length is 172-feet. So we stay in our chosen row and move to the right. There are no valid choices for vents sized at 1-1/4", 1-1/2", 2" or 2-1/2"- ignore those choices. But the table has populated values for 3", 4", 5", and 6". We must evaluate.

The maximum developed length for the 3" vent choice is 22-feet. Not adequate. Keep moving to the right. The maximum developed length for the 4" vent choice is 84-feet. Still not enough. The maximum developed length for the 5" vent choice is 260-feet. Which is enough. Good.

But wait, the 6" vent choice is also valid with a maximum developed length of 660-feet. At first, it appears that a 5" vent or 6" vent could both be correct answers.

Go back to the question. Right at the beginning it asks for the minimum size. Therefore, the correct answer is answer 2: 5-inch.

I hope that made sense, breaking it down part-by-part of the question. If you are still confused, feel free to comment back about what is tripping you up.

Thanks for reaching out, and good luck studying!

Passed the P2!!!! Thank you again for all your help!

Gabe and SI Certs Team - Just passed the Commercial Plumbing P2 Exam! This now makes (11) ICC Certifications that I have obtained by directly working through your courses and the amazing help from not only you personally but your entire team. As I am moving now onto the E2 Commercial Electrical to complete the suit of Commercial Building Inspector C5, I just wanted to thank you again! I could not have achieved all these certs (I have the most in my company now - HA!) without all the one-on-one assistance, and prompt responses to walk me though my questions so I understand, not just know what to answer on the exams. Thank you!

Their customer support is unbelievable!

This app is perfect and their customer support is unbelievable! All I had to do was follow the class, step by step, and I passed all 3 tests (first try) to become a reinforced concrete inspector. I was extremely nervous about the plans-reading test, but I passed that as well.

I was especially impressed with how helpful these guys are when I had questions. They always respond within a day or two and answer all my questions, even after my paid class had ended. I am now taking their masonry class and so far it is equally impressive. I highly recommend these classes.

Finally, I passed Reinforced Concrete.

Hey Gabe, I just called you to tell you I finally passed this test! You know how hard this has been for me and what I've gone through, particularly since English isn't my first language. I am extremely grateful for everything you have done. There's no way I would have passed this test without you. If you're ever in Washington and need a place to stay let me know. Now on to PT with SI Certs.

I am a structural engineer by profession. Thank you for this training.

The training has really saved me a lot of time. I am a civil engineer with a structural emphasis and your material was very good and accurate. The plan reading part was very helpful to me to prepare for this test. Now that I've passed Reinforced Concrete with you, I'm doing your PT course. Believe me this has saved me a tremendous amount of time.
