Qwater 4” Well Developer Surge Block

Description

Qwater 4” Well Developer Surge Block. Condition is "Used". Shipped with USPS Priority Mail Medium Flat Rate Box.
I used this for one shallow well project. All 4 wipers included (2 installed) and are in good condition. Check valve ball is in-place as well.
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.
