Section 5: Pump Cylinder & Drop Pipe Installation

In this section we will review the installation of the entire string of new drop pipe with the pump cylinder at the bottom. *** Be very cautious. Dropping the entire string down the well is possible. Follow these directions, carefully — step by step! ***

Preparation and Inspection

When you receive your pump system, the drop pipe kits arrive in a nine foot spiral-wound fiber tube. The male threaded ends will be protected by a plastic cap. You need to remove that cap prior to installation.

*** WARNING: Be sure to identify the top drop pipe, and install it last. A 1/16” weep hole is drilled in it 48” from the top (or further down, if you requested a custom weep hole). The weep hole has a 1" circle around it and the word “weep” handwritten beside that, circle and word in thick felt pen. Put the top drop pipe aside to be installed last. ***

Each sucker rod is shipped inside of a drop pipe. The ends of the spiral-wound fiber tubes are wrapped with stretch wrap and tape. Very occasionally, from rough handling during shipping, a sucker rod has come out of the shipping tube, and then bent upon itself. That ruins the sucker rod, fracturing the fiberglass—but the damage may not be totally obvious.

Therefore, before installation, examine the length of each sucker rod visually and by running your hand slowly over it. The surface should be smooth with no breakage in the fibers.

Wipe outside of all pipe, and rinse inside of pipe with the dilute (20:1) bleach solution, taking care to remove any debris, dirt, PVC sawdust, etc. Place them where they will not be contaminated prior to installation.



Connecting bottom sucker rod to the piston rod of the pump cylinder.Take the pump cylinder, and using the vice grips, connect the male threads on the piston rod and the female threads on a sucker rod. Use as much force as necessary.

Stop when the two ends are shoulder to shoulder.

SPECIAL NOTE on reinstallation

The female sucker rod end has a dimple in the skirt that acts as a mechanical lock by disrupting the threads. When the Simple Pump is installed and removed then installed again, the effectiveness of the mechanical lock is compromised and it is possible for the threaded connections to loosen. We recommend Loctite non-permanent thread bonder on the male/female sucker rod connections in systems that have been installed more than three times.


Do NOT place the fiberglass lift rods in direct, summer sun before or during the installation process.  
This can dramatically increase the temperature of the stainless steel rod ends and fiberglass rods. Immediate immersion in cool well water can then shock the epoxy bond between rod ends and fiberglass rods, which may result in epoxy bond failure and pulling off of the rod end.
(Please note: In normal installation and usage, this bond is enormously stronger than needed for operation of the pump.)


There are three possible types of drop pipes, shown here
- with a stainless steel coupler
- with a bell-end joint
- or with a PVC coupler.

NOTE: The instructions following show photos of just the bell-end. The installation steps for the other two types are the same.

Never use a liquid sealant/pipe dope.
Never use more than three layers of Teflon tape.

      PVC Drop pipes. Schedule 120 and Schedule 80.

Take the first drop pipe. Apply three wraps of Teflon tape on the male threads of the drop pipe (right).

Bring the sucker rod that is already attached to the piston rod into the male end of the drop pipe. Thread the drop pipe into the pump cylinder. Be careful not to cross-thread. Tighten as far as possible by hand.

Applying three wraps of Teflon tape to the threads of the drop pipe.Further tighten the PVC drop pipe into the body of the pump cylinder (by one-half revolution), while holding the pump cylinder with a channel lock.

*** WARNING The amount of torque desired is ONLY about a half-turn beyond hand tight. The drop pipe threads are tapered, so there is no need to use a heavy pipe wrench or any other tool that generates a great deal of torque. ***
