  1.  Attach 1.5" NPT pipe to the top of the well developer. (If using a wireline, We recommend using 10ft of iron pipe as a weight)

  2. continue to connect solid riser pipe until you hit the bottom and extend beyond the surface of the well. 

  3. Attach the upper valve assembly to the final piece of solid riser pipe.

  4. With the Upper Ball Valve closed, surge system up and down five strokes

  5. Open the Upper Ball Valve and surge (fast - down and slow - up) until water flows out of the tubing

  6.  Continue to surge the well until the discharge is sediment free and/or the water clears

  7.  Follow proper decontamination procedures before using in another well. (Qwater Does not suggest reusing well developers)

The Environmental Series works with a wide selection of materials. SIzes 1.25"-2" can be used with ​​Poly tubing, Pex tubing, glued PVC or, most commonly Environmental Flush Treaded PVC. 3/4" and 1" work with 1/2" OD Poly Tubing and1/4" NPT

​​

  1. Attach the Well Developer tool to 1/2-inch PVC Riser using the provided set screw or the 1/2" PVC Male NPT/Flush Thread Adapter.

  2. Lower the Well Developer to the bottom of the well and attach the Upper Ball Valve Assembly and tubing to the top of the PVC pipe

  3. With the Upper Ball Valve closed, surge system up and down five strokes

  4. Open the Upper Ball Valve and surge (fast - down and slow - up) until water flows out of the tubing

  5. Continue to surge the well until the discharge is sediment free and/or the water clears

  6. Follow proper decontamination procedures before using in another well. (Qwater Does not suggest reusing well developers)

​Tubing Riser Attachment and Development Procedures

Polyethylene (Flex) Tubing Riser Instructions - Use off-the-shelf polyethylene tubing from a roll.  Cut the end of the polyethylene square (clear, white or black) and turn the tubing four turns, or until tight, into the Qwater Well Developer.  Roll the tubing, with the Qwater Well Developer attached, to the bottom of the well.  Cut the tubing 5 to 6 feet above the top of the well.  Insert the tubing end into a 5-gallon bucket (white, if available). Either clamp the tubing onto the bucket or drill a ½-inch hole into the bucket near the top and insert the tubing through the hole.  Surge slowly up and quickly down. Allow one stroke per foot of distance to the water level to bring water to the surface (i.e., 20-foot water level = 20 strokes, etc.)

​

​PVC (Rigid) Riser Instructions - Use 1/2-inch Schedule 40 or thin wall (DWV) PVC pipe from your local hardware store for the Qwater Well Developer riser.  Tighten the small setscrew on top of the Qwater Well Developer into the PVC pipe.  Lower the Qwater Well Developer into the well, adding PVC lengths as needed, holding each link at the top with vice grips.  Once the Qwater Well Developer is at the bottom of the well, cut the PVC 2 to 3 feet above the top of the well casing and add the quarter-turn valve, with 90-degree elbow, and then add 6 to 7 feet of 1/2-inch ID clear vinyl tubing.  (See Upper Valve Assembly photo.)  Insert the tubing end into a 5-gallon bucket (white, if available).  Either clamp the tubing onto the bucket or drill a 5/8-inch hole into the bucket near the top and insert the tubing through the hole.  Note that the smaller size Qwater Well Developers (3/4-inch and 1-inch) and larger size Qwater Well Developers (1.25-inch, 1.5-inch, and 2-inch) have a tapered bell socket for gluing (solvent weld) or using a setscrew to secure the tubing in place. Deeper in the socket, below the bell, are 1/4-inch female pipe threads (in the smaller size QWDs) and 1/2-inch female pipe threads (in the larger size QWDs).

​

​Development Procedures - Beginning at the bottom of the screen, push and pull the tubing up and down (up slowly / down quickly).  If the well is unable to produce enough water, pinch or close off the flow with a quarter-turn valve so that the muddy slurry remains in the well, and is allowed to be used to surge fluid back and forth through the screen.  Development time (usually 5-10 minutes per 5 feet of screen) depends on the range of grain sizes, screen slot size, length, and clay content.  Generally, development should continue until the gritty material is no longer being pumped into the bucket.  Note that since the Qwater Well Developer surge block method is a very aggressive method, the water may continue to appear muddy.  Removing the flexible wiper from the PVC body after a few minutes of surging will allow the valve to clean the water more quickly, if so desired.

​

​Note that the quarter-turn valve (photo 2) is used to keep fluid in the screen in low-producing wells; and the hole in the bucket holds the tubing (photo 8).  Drill a 1/2-inch hole for 3/8-inch tubing or a 5/8-inch hole for 1/2-inch tubing. Clear vinyl tubing helps in observing the fluid.
