DEEP WELL PUMP INSTALLATION
(4" DIAMETER CASED WELL)
For wells over 25, but not exceeding 70 feet in depth, the
3/4 HP Convertible Deep Well Pump is recommended.
However, the 1/2 HP Deep Well Pump may also be used for
depths not exceeding 70 feet.
General materials needed for the convertible pumps:
• One can PVC cement (read instructions carefully)
• One can thread compound (read instructions carefully)
• Two 1" female PVC adapters
• Enough rigid 1-1/4" PVC pipe and couplings to reach from
bottom of well to pump (delivery pipe)
• One 1-1/4" PVC elbow
• One 1-1/4" male PVC adapter
• One pressure regulator Kit (includes fittings, tubing, and
1/4" plug)
• One pressure gauge
REMINDER: ALL JOINTS AND CONNECTIONS MUST BE AIRTIGHT . A SINGLE PINHOLE
LEAK WILL PREVENT THE PROPER OPERATION OF THE PUMP . USE THREAD
COMPOUND ON ALL THREADED CONNECTIONS UNLESS SPECIFIED OTHERWISE .
TO INSTALL A CONVERTIBLE
JET PUMP:
1. Thread 1-1/4" close nipple into foot
valve. Thread the other end of 1-1/4"
close nipple into bottom of deep well
ejector. Hand tighten, then tighten 1/4
