Pipe runs (Cont.)
The more 90's used the more force is needed to pull the hose out of the valve.
Try not to use more than four 90's for each valve.
Try to avoid back to back elbows (fi gure
10). Try to space them out as much as pos-
sible.
It is important to design the pipe runs so
the hose is stored on one level (fi gure 11).
Avoid storing hose on two diff erent levels
(fi gure 12).
