4.5" Well Developer, Sch40

The Production Series Qwater Well Developers are reusable. Made of tough ABS body and molded 1.5-inch steel female NPT pipe fitting for attaching to a weighted wireline or drill pipe. Although the casing/screen wipers are also constructed of tough polyurethane, there are four wipers on each ABS body to ensure that the tool only needs to go in the borehole one time. The wipers can easily be replaced in the field with a regular slotted screwdriver to remove the stainless steel bolt and slide the spacers on and off the ABS body to replace or change wiper sizes. Advantages of Qwater Well Developers The unique flexible vinyl wiper creates a suction seal to pull water into the screen Constructed of environmentally inert materials The internal check valve ball prevents water from flowing back into the well and won't clog with sediments Production Series Qwater Well Developers are capable of lifting water with ball valve over 100 feet A one-person operation, which is fast and saves time Production Series Qwater Well Developers are reusable How to use: Step 1: Attach the Well Developer tool to 1.5" PVC Riser using the NPT Thread at the top of the tool. to connect to flush thread pipe, use an NPT to Flush thread adapter. Step 2: Lower the surge block to the bottom of the well and attach the valve assembly and tubing to the top of the PVC pipe Step 3: With upper ball valve closed, surge valve up and down five strokes Step 4: Open the upper ball valve and surge (fast - down and slow - up) until water flows out of the tubing Step 5: Continue to surge the well until the discharge is sediment free and/or the water clears Step 6: Dispose of the Qwater Well Developer tool to avoid cross-well contamination Attachment of Tool –The top portions of the 4.5-inch surge blocks are fitted with a 1.5-inch female tapered NPT pipe thread for attaching a 1.5-inch male pipe thread. If a wireline is selected to lower the development tool into the well, it is recommended to attach a 10-foot long section of iron pipe directly to the top of the tool for weight to help lower the tool. Care should be taken not to over-tighten the threaded fitting. Hand tight plus one-half turn is sufficient. If the check valve assembly is to be used to pump water from the screen, a PVC riser should be attached to the top of the weight pipe and extended from total depth to land surface. A 90-degree elbow is recommended at the top to direct the purge water away from the wellhead. If the drill pipe is attached above the top of the tool, care should be taken to ensure that the weight of the drill rod does not crush the tool on the downstroke into the bottom of the well.
