F.  DISCHARGE LINES 

 

1.  Siphoning 

 

Avoid ending the discharge line lower than the liquid being pumped 

unless a siphon breaker is in use.  Without a siphon breaker installed, 

siphoning may damage the pump. 

 

2.  Valves 

 

When using a discharge line throttling valve, it 

must 

be the same size 

as the largest pipe to reduce friction loss.  Do 

not

 install a throttling 

value in the suction line. 

 

If using high discharge heads, Weir Specialty Pumps suggests a 

throttling valve coupled with a system check valve in the discharge 

line. When the pump is stopped, this helps ensure the pump is safe 

from reverse rotation and extreme shock pressure.
