DEEP WELL PUMP INSTALLATION
(4" DIAMETER CASED WELL)
For wells over 25, but not exceeding 80 feet in depth, the
twin ejector must be installed down inside the well rather
than attached to the front of the pump. Materials with part
numbers are quality Water Ace parts.
General Materials
• One Jet Tank System #R-520C-T7. Includes: 1/2 HP jet pump
mounted on a 7-gallon diaphragm pressure tank, pressure
gauge # RG-2, and twin ejector with gasket, bolts, venturi
tubes, and foot valve
• One can PVC cement (read instructions carefully)
• One can thread compound (read instructions carefully)
• One 1-1/4" close nipple
• One 1" x 4" nipple
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.

nipple into bottom of twin
ejector. Hand tighten, then tighten 1/4

Thread 1" x 5" nipple into smaller hole.
Only hand tighten venturi tube. Tighten

tube and into ejector. Thread
a 1" female PVC adapter onto
1" x 5" nipple. Tighten adapters 1/4 turn
with crescent wrench.
Subtract five feet from the

depth of your well. This is

the total length of PVC pipe
and couplings to cement onto
both the 1-1/4" male and 1" female PVC
adapters. Cement a section of PVC pipe
to each adapter.
