Can anyone explain (or forward a faq) where I can find out more about
the intended use of the following type of elbow fittings:
1. 90deg Street Elbow
2. 90deg Street Closet Elbow
2. 90deg Closet Elbow
3. 90deg Long Turn Elbow
4. 90deg Long Turn Street Elbow
I saw these variations on a manufacturer's catalog (http://
www.nibco.com/assets/plasticfit.pdf) and am curious to learn more
about them all. Specifically, is the term "street" when the fitting
is male/female? Is there a special use for a "long turn" elbow?
I'm not sure about closet elbows.
You're right, that a "streeter" has male and female ends. Long turn means a
more gentle arc. Since it's not slamming the water from one directon to
another, it produces much less resistance to the flow of water. I use long
turn / radius whenever possible.
Others have answered about the meaning of "Street" here. As for long
turn 90s, they are required by the plumbing code (UPC) for drains
whenever the outlet of a 90 is horizontal. So if you use a 90 to take
a drain from vertical to horiztontal, or from horizontal to
horizontal, you need a long turn 90. To take a drain from horizontal
to vertical, you can use a regular 90 (not a vent 90). Of course
"horizontal" here really means sloped at 2% or more to provide
