Hi,
I'm took a quiz for a plumbing course I'm taking, and I swear I cannot find the answers to these questions. The quiz is based on the 2003 IRC.
1.What is the minimum size for a dishwasher discharge hose?
2. Gas piping test...1.5 or 2 X the nominal pressure...or something. I know it's 10psi for 15 mins, but that wasn't an option.
3. Is a clothes washer standpipe considered an air gap or air break?
4. What is the minimum depth of a hot water heater pan? What about the min size of the drain line from the pan?
5. What is the minimum depth of a shower pan?
6. Does the code state where the main water shutoff has to be? Within 5 feet of the house, etc?
7. What is the max slope of a combination waste/vent system...expressed in %. Like, is it 1%, 2%, or 3%?
Any help on these would be much appreciated!
