Ok revenge I know a very easy way to draw. First you make a compass on the top of the paper , but you add a up and down line and rotate your normal compass... It sounds stupid but it works when you draw the east west north and south you draw them at a 45 degree angle some say 30 degree but ether will work for a starter drawing.... Now you have your compass and north can be where ever you want it, it doesn't matter at all But if you are drawing for a real job I'd make it match the site plan. If drawing a sanitary drain system you put a line with a S on the edge of the paper to represent the sewer and where your drain will run to So now you start with a main trunk and what ever direction it goes in the building you draw it parallel to the line in the compass for that direction so a riser or drop will always go up and down. When I practice I always put north on one of the top sides of my compass...draw a main then any branch lines . All lines will be parallel to one of the compass lines after branches draw risers witch will go up and down on the paper . And draw fitting directions like a wye or combo and San tee. Then draw vents in dashed lines. Its hard to explain like this but I tried. I ways amazed when a was shown and drew a lot to practice for my test. But wasn't required to draw for test just drew to make a parts list for the doll house Don't hesitate to pm me if you want more explanation ..... Here's a crappy drawing with out fittings but the compass is the key for this method. Jut draw all lines to mach it and you will end up with a 3d drawing

Thanks tex helped out a bunch i heard for the master you no longer play with the doll house. but they do want an isometric so i gotta learn how to do and if they do make you play with the doll house gona be kind of hard to do with out knowing how to draw an isometric. Gots to start learning quick btw. When i took my journey man i did a basic drawing for drain, basic for vent and passed it fairly easy. but the master i heard its 26 fixtures. I dont think my way gonna work this time.

Isometrics are not that difficult once you get the hang of it. You will need to practice.
All vertical pipes such as waste stacks and vents, are also vertical on your isometric paper.
All horizontal pipes are drawn on a 30 degree angle on iso paper.
You need a '30-60-90' triangle in order to draw isometric drawings. You'll also need isometric paper.

Those loom great Tommy I wasn't sure if it was 30 or 45. Can you get that paper at any office supply ??
Or you can go to the link I provided in the second post of this thread and print it yourself.

I saw that site but I think it would be cheaper to buy it in a pack then use the printer. My bride would kick my butt for using all the ink. Now if I just wanted a page or two that would be the way to do it.... Cool site tho

Use Isometric Graph paper, it helps a lot. here is a site you can print your own for free. http://www.waterproofpaper.com/graph-paper/isometric-paper.shtml





That's pretty cool Sewer Ratz. I just printed out a sheet of that isometric graph paper. It amazes me the resources located here at PZ. The wealth of knowledge and experience from all these professionals. I wish I would have had access to this site years ago when I was coming up. This site and it's plumbers rock!...:thumbsup:

Hey revenge don't spend to much time practicing drawling. On the test it is not isometric, one colored pencil for drains and another color for vents. Although knowing how to draw an iso may come in handy, don't get too caught up in it.

The easiest way that I was shown during level2 at school was to only ever have the triangle in 2 positions on the paper and never any other way! The long side adjacent to the 90 degree angle always at the bottom and the triangle only flipped on the short side.You then only have 2 positions to work with and it'll be isometric. Our teacher went nuts if you did it any other way and it works. If you get used to this - it'll be pi$&easy. All you'll have to do is think about the direction the pipe is going and how you fit it onto the paper best. I used to hate isos - not anymore!

Good luck.

Those 4 lavs are not vented correctly. You can common vent 2 of them, and AAV the others if you want, but make sure your drain is sized for 4 DFU

Is this better? I also added (2) c.o.'s on lav stacks.

By the way, for our state exam, you are not supposed to make any changes on the drawings. Regardless if they're code or not, they want you to sketch it exactly the way they give you the floor plan.
