General Rules:
1. Measurements taken from fittings centerline (All SCH. 40 Pipe).
2. Maximum difference in elevation from valve outlet to any nozzle is 10'.
3. Largest diameter pipe must be used first and decrease in size as installation moves away from the tank.
4. No traps in the piping.
5. Two elbows are allowed in place of a swivel. Elbows used as a swivel do not have to be subtracted from the total allowed.
6. Maximum of 25 elbows.
7. Maximum of 5 elbows between nozzle and preceding tee.
. 8. Maximum flows for 1/4" pipe = 6 flows.
9. Maximum volume allowed for 1/4" pipe from tee to nozzle is 410 ml. (20 ft). .
Additional rules for PCL 600:
1. Split piping must be used with a maximum of 14 flows on a side.
2. No nozzles before the split.
3. Minimum 1/2" pipe must be used to the first split.
