What amount of reduction is permitted in a 3 inch cast iron drain pipe?
The size of the pipe cannot be reduced in the direction of drainage flow.
By 1 inch.
I’ve see it done at the shower only (not tub), washer standpipe and vent pipes…
[FONT=Times New Roman][size=2]The size of the drainage piping shall
not be reduced in size in the direction of the flow.
The size of the drainage piping shall not be reduced in size in the direction of the flow. A 4-inch by 3-inch water closet connection is not considered a reduction in size.
Well done Sam, figured I’d try a trick question…
Thanks Mike, I guess the early bird analogy worked out this time. My friends call me Dave.
Now you can take those Now books and next week make a question on the felt dots, still waiting…lol:p
Thanks guys. The felt dolts mystery was solved by Fred, they are markers for termite “bait” stations, a green plastic container that has a piece of wood inside of it to ‘lure’ termites. Which seems like a bunch of BS to me, they put the dots on the wall so they can find them in the wood mulch they are buried in:roll:
