Water Main 90 Bend

[IlliniEI]

I'm being told that I can't use a 90 degree bend for a new water main. I've stated that we will use thrust blocking, but I'm required to use 22 1/2's instead to make the turn. Is this just a jurisdictional thing or is it bad design to use a 90 with thrust blocking?

Type and size of pipe?
Pressure?

But looks odd to say the least. That's why they make 90 degree bends...

There are no design issues with 90 degree bends in water distribution systems. Are there other buried pipes in the vicinity of the proposed installation?

Maybe just an individual preference of whoever.

I can only guess that someone had a bad experience with an inadequate thrust block.

Typical 8" ductile iron water main serving one street. I was under the same impression that's what they're made for.

No real constraints in the area from other utilities or structures. I'm leaning towards individual preference as well, but wanted to make sure I haven't been specifying plans incorrectly.

There are some out there that think the water flows better in 2 - 45 degree instead of 90 degree. However, there is no science behind that.

No science only makes it that much more believable to some.
