Friction Loss Through 8" Fittings
Using fittings creates friction loss:
Below we show the comparison of friction loss of "average" fittings compared to "average" feet water travels inside pipe.
Example is: using a 1/2" 90 degree elbow is approx. the same as 1 1/2' of pipe
The less fittings that you are able to use, the less friction loss you'll have!
