Gas PipingQuestion 255 of 360
A sediment trap is typically built from a tee and a nipple. What is a reasonable minimum length for the capped drip nipple so it can actually collect debris?
a.About 1/2 inch
b.About 3 inches
c.About 12 inches minimum by code everywhere
d.Length does not matter
Explanation
The capped drip leg needs enough depth, commonly on the order of about 3 inches, to actually collect condensate and debris below the run of the tee. A stub that is too short cannot trap anything. Follow the appliance instructions and adopted code, which specify the required configuration and minimum dimension.
