In fact, I still do them! They remind me of diagraming sentences way back in grade school - thank you Sr. Mary Emma!
Last week I did four of them for different homeowners. Architects and builders also hire me to draw the complex isometric drawings.
"Why are the isometric drawings important, Tim?"
That's a great question. In my opinion, there are three primary reasons:
1. It's so very important that you have the correct pipe sizes for fixtures and fixture groups shown on the drawing. The drawings ensure you understand what the minimum pipe sizes must be for both drains and vents.
2. Fixtures must be vented properly for the system to work. You'd be surprised how many plumbing systems are not vented properly. An isometric drawing shows all the vent pipes as dashed lines. Sometimes you can have a drain pipe do double duty! It can drain a fixture and be a vent pipe for another one at the same time.
3. The drawing communicates to the plumbing inspector that you know what you're doing so when she/he comes she/he won't deliver the bad news to "rip it all out and start over".
I also draw water line layouts and draw & size gas lines too. One-stop shopping!
I delivered plans to Marty just two days ago for a slab house he's building down in Arkansas. He responded, "Thank you again, I appreciate the help, and nice to see the service you are providing!"
That's quite enough for a Sunday. As you read this on Sunday, I'll have been participating is a worldwide IARU radio contest for at least 24 hours. Here's what the ARRL website says about this annual event:
"To contact as many other amateurs, especially IARU member society HQ stations, around the world as possible using the 160, 80, 40, 20, 15 and 10 meter bands."
I'll be operating doing just Morse Code and it's my goal to contact at least 100 other stations. I'll report next week if I achieved the goal!
