Hopeing to get a little more input on this one. Id give the answer now, but what fun is that.
Hint, my code states fixtures unit loading a little closer to Marks on this one. Remember(and I believe this to be a pretty universal thing) you can have two toilets , and many other fixtures as well,on a 3" horizontal line, and toilets are 3 fu each. Just something to pursuad your answers.
What are you using to hang your PEX tubing?Quote:
All right, here's the answer given in my code(upc). B, 32 inches.
I personally like to hang it every 18 to 24 inces just strictly for appearance. But even then its tough to make this stuff look good when exposed. Don't get me wrong, I love the pex, but I try to use it mosty in concealed or covered areas, and still use copper in mechanical rooms etc, for the looks of it. Now, in crawl spaces, I've been known to go over the 32" code. Sometimes in a tight crawl space I just want to get that stuff up and get the hell out. Lol.
Snails, plastic two hole pipe straps, suspension clamps, staples..
I use plastic two hole straps for pex, as my code states you must use similar materials for hangers,(plastic for plastic pipe, copper for copper pipe, galv for galv pipe etc). The pic is the straps I use most often for pex. Do you have a better hanger in mind. I'm open to options.
Glad to see you here iamgrowler. Id love to see your take on some of these questions. I believe you teach this stuff, and I'm here to learn.
Now, back to it. Answer to #13 is B. (upc, table 7-3 and 7-5.
I will note that Marks fu loading is close to mine, but mine allows 8 fu for horizontal 2" !6fu for vertical 2".
On to the next...
#14. The required clearance in front of a 3 inch cleanout is_______
A. 6
B. 12
C. 18
D. 24
Number 14 is C... 18 inches (in my area).
"C", of course.Quote:

The actual code reads: " . . .shall have a clearance of not less than 18" in front of the cleanout".
Which means, given the ambiguity of the question, that "D" would have also been a correct answer.
The question should have been: 'the minimum required clearance in front of a 3 inch cleanout is_______'.
No, those are what I use as well.Quote:

The only consideration vis a vis isolation that I'm aware of is that piping must be isolated from incompatible materials.
Then again, if you took the Code literally (section 314.5), you wouldn't be able to use the plastic two hole pipe straps for PEX, because the manufacturers state in their installation guides that the piping must be allowed to move freely to counteract expansion -- Plastic two hole pipe straps lock the pipe in and do not allow for movement.
#14. The required clearance in front of a 3 inch cleanout is (C) not less then 18 inches.

Okay, you got me. You are correct. Chapter 3 section 314.4 in upc 2006 edition states... piping shall be isolated from incompatible materials. I was trying to go off memory(not so good) instead of finding the facts. I don't know where I picked up the similar materials, someone must have snuck it into my subconciouse mind. Anyway, glad to hear you use the same hangers.
As far as the terminology of questions, I agree, some of these are kind of like trick questions. I didn't wright them, just studying them.
Growler, if you don't mind my asking,, what code do you fall under. And are you an instructor, inspector, or working plumber.
Yep, c it is.
#15. A refrigerator used to store food and that requires drainage shall be drained by means of________.
A. an indirect waste pipe
B. a direct connection
C. both A and B]
D. no drain required
No worries, we've huffed a lot of solvents and glues in our career.Quote:

Well, hopefully this saves you some money in pipe hangers -- Copper clad two hole pipe straps cost a great deal more than plastic two hole pipe straps.Quote:

Not that it matters, or that it's any of my business, but is this part of your required continuing education classes, or are you studying for your Journeyman's exam?Quote:

I fall under the UPC, although for how much longer remains in doubt -- I'm thinking the 2009 revision of the UPC may very well be its last.Quote:
Growler, if you don't mind my asking,, what code do you fall under. And are you an instructor, inspector, or working plumber.
Let's face it -- The UPC is pretty much a Left Coast phenomenon and if it doesn't show more flexibility in the adoption of new standards, practices and acceptance of new materials and devices, then the Unions are going to push to have it abolished.
As for the other part of the question: I am a working Plumber, but I also teach a class in code compliance, focusing on newly adopted code revisions -- Not yet certified as a Continuing Education class, but I'm working on it.

Just getting ready for the masters exam.
Anwer to #15 A.
#16. Sheet metal, constituting a part of any vent connector, shall be at least_______.
A. 0.0304 inches
B. 0.0450 inches
C. 0.0500 inches

The correct answer is "A".
Keep 'em coming, MGD. :)
I kind of dropped the ball, been busy lately.
Your correct, A it is.
#17. One material not approved for the installation of an external trap for a urinal is _________.
A. cast iron
B. cast brass
C. drawn-brass tubing traps
D. ABS.
In my area the answer is C... drawn-brass tubing traps. Urine has a tendency to just wreak havoc on any thin walled brass. Of course, in Massachusetts... we can't have external traps on any urinal... all must be integral traps.
Here, we can use cast iron or cast brass commercially and ABS and PVC for residential installations of urinals.

This is great -- Got to love it when the question is germane to recent events.Quote:
#17. One material not approved for the installation of an external trap for a urinal is _________.
A. cast iron
B. cast brass
C. drawn-brass tubing traps
D. ABS.
We installed an antique urinal in the condo of a Microsoft gazillionare a few weeks ago and spray-painted the external tubular plastic PVC p-trap with nickel spray paint to match the rest of the finishes in the bathroom -- Even taking the time to sand it in one direction to give it a brushed nickel finish.
When the Inspector saw this, he rapped on the trap to see what it was made of, then asked me why we didn't simply seek a variance to install a drawn brass p-trap in the correct finish.
Long story short -- The Customer/Designer specified drawn brass nickel plated bottle trap was in a vanity drawer not less than three feet away as the Inspector made his comment, and was installed less than 20 minutes after he signed it off.
Anyhow -- The correct answer is (C).
Just goes to show that the code book is basically a guide book. The fact is, the inspector (or authority having jurisdiction) can OK anything he pleases. I think its awesome that he signed off on it. Not only did he make it his liability(instead of yours), but it made the customer happier with you for doing what they wanted.. That is what I call a win win situation for a plumber.
'Kay -- I was right up there with you up until this point.Quote:

Huge difference.
Oh, I misunderstood. Thought you were saying he signed off while knowing you were going to install the trap. Oh, well, custermer is still happy.
Answer to #17 is C.
#18. Hub and spigot cast iron piping in 10 foot lengths, installed horizontally, shall be supported at intervals of not more than______ feet.
A. 5
B. 10
C. 12
D. 15
The answer is A. Not more than 5 ft
Hi all:
In my area, the answer is every 10 feet (at every hub and every change of direction).. so answer is B
For 5 foot hub & spigot pipe it's every 5 feet (every hub)... ;)
MARK
SPC, Chapter 10, Section 103.2 HORIZONTAL CAST IRON SOIL PIPE,Quote:
#18. Hub and spigot cast iron piping in 10 foot lengths, installed horizontally, shall be supported at intervals of not more than___10___ feet.
Cast iron soil pipe shall be supported at not more then five foot intervals on five foot lengths and ten foot intervals on ten foot lengths. Hangers shall be located as near hubs as possible.

Update.
After procrastinating taking the master plumber exam for almost a year, I finally had time to bite the bullet. So I drove three hours to the testing area, got a hotel, and studied one last time. Long story short,, I am now officially a licensed master plumber.
Goodbye journeyman, hello master.
Congratulations!! And now, back to work !:D:D:D
Thanks Milo. And yep, after all, its just a title of achievement, but I will still have to crawl up in the attic full of thirty year old pink unfaced insulation on Monday. In the back of my mind ill be thinking, well at least I'm an itchy master instead of an itchy journey.lol.
Hi Lee...
Cigars are on me... :) Everyone grab one... special occasion the way I see it!
Without too much fanfare... seriously, congratulations on your achievement!
Regards...
Mark
Congrats Lee! Way ta go! Party time! Save me a invite. Tom
Thanks for the congrats guys, I truly appreciate it.
As one who can appreciate the distinction between a Master and a Journeyman under the UPC (the strictest Plumbing Code in the Lower 48), I offer my congratulations as well.Quote:

Thanks for the heads up Widdershins.
I look forward to the day that all of the united states, if not the whole world fall under one stardard plumbing code(of course with certain local variences). Although I don't see that happening any time soon, I sure would like to see steps taken towards it in my lifetime.
