During low discharge head applications under 30-feet or 9-meters, Weir 

Specialty Pumps advises a bypass line running back to the wet-well.  Place 

the bypass line at the cut-off point of the low-level pump or 6 inches below 

the level of the water. 

 

 

Occasionally, installations of the bypass line will end with a 6 to 8 foot length 

of 1½-inch I.D. 

smooth-bore

 hose.  In these cases, any air and liquid that is 

vented during priming will vibrate the hose, breaking up remaining solids, 

grease or other materials residing in the line.  This reduces clogging.  

 

 

 

BYPASS LINES MUST BE SECURED AGAINST BEING DRAWN INTO THE PUMP 

SUCTION INLET WHEN RETURNED TO A WET WELL. 

 

 

 

Weir Specialty Pumps advises the installation of pipe unions in a bypass line 

at every 90º elbow to facilitate disassembling the parts for maintenance and 

repair. 

 

 

If the pump is used on high discharge head applications extending more than 

30 feet under full working pressure, a larger volume of liquid may be 

bypassed back to the wet-well.  Such an occurrence will reduce the pumps 

performance.  To avoid this, Weir Specialty Pumps advises installing a 

WSP™ ARV (WSP™ Automatic Air Release Valve) in the bypass line. 

 

 

WSP™  ARVs offer low maintenance and high levels of dependability.  For 

more information, see the WSP™ ARV in this section for information on its 

operation and installation.  Contact your local WSP™ distributor or the factory 

to select a WSP™ ARV that fits your application. 

 

 

When installation of a WSP™ Self-Primer (WSP) Pump involves submerged 

suction such as those in underground applications, Weir Specialty Pumps 

advises installing a pipe union and manual shut-off valve in the bleed line.  

This allows service staff to maintain the valve without being required to shut 

down the station.  This also minimizes any chance of flooding.  A full opening, 

ball-type valve that prevents solids from plugging the line must be used in 

applications where a manual shut-off valve is located 

anywhere

  in the air 

release piping. 

 

 

 

 

FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN SEVERE INJURY.   

 

WHEN A MANUAL SHUT-OFF VALVE IS INSTALLED IN A BYPASS LINE, IT MUST 

REMAIN OPEN DURING OPERATION.  CLOSING  THE MANUAL SHUT-OFF VALVE
