The valve outlet opening is at the opposite (small) end of the valve body. It
also has 1-inch standard NPT pipe threads. A bleed line that drops back to
the wet-well or sump must be connected to the valve outlet. It is imperative
that the bleed line is the same size or larger than the inlet piping. When
possible, do not use elbows in a bleed line made of piping.
NOTE:
Every WSP™ ARV should be modified to accommodate an independent
bleeder line that can slope backward toward a sump or the wet-well (Figure
18). When more than one WSP™ ARV is installed in a system, each valve
must be fitted with an independent bleeder line. Never use a common
manifold pipe. Contact your local WSP™ distributor or the factory for
information about WSP™ ARV installation for individual applications.

H. ALIGNMENT
To maximize mechanical operation of your WSP™ Self-Primer Pump be sure to
correctly align your pump and its power source. This is crucial to maintain high levels
of performance. It is essential that both drive and pump in the V-belt driven and the
flexible coupling systems are mounted to allow their shafts to be in alignment and
parallel to each other. Prior to commencing operation, the operator or service staff
must
inspect for correct alignment once the pump and piping have been installed.
NOTE:
Check Section IX OPERATION, Part B. Start-Up for Rotation prior to final
pump alignment.
Both drive and pump are aligned prior to being shipped when the Weir Self-Primer Pump is
mounted at the factory, During shipping and handling, the pump and drive may lose the
factory alignment. Therefore, it is vital that both drive and pump be inspected and realigned
