Company Features New Water Main Flushing System

At the American Water Works Association's annual conference and exhibition, Kupferle Foundry Co. will be exhibiting a new automatic water main flushing system.

Most distribution systems have several locations, normally dead-ends, where chlorine residuals are difficult to maintain. These locations require frequent, and expensive, visits by water system personnel. Kupferle's new #9600 or #9700 Automatic Blow-Offs can flush these water mains automatically, saving man-hours and travel expenses.

Kupferle #9600 Automatic Blow-Off

The #9600 Automatic Blow-Off is a permanent flushing point, installed in an insulated fiberglass enclosure, which can flush directly to the ground, or divert the water flow to a storm sewer or culvert.

Operators can set the pre-determined flushing times for any duration. The valve controller is simple, and remains with the unit at all times. No hand-held controller is required. Flushing choices are twice per day, once per day, every other day, or weekly.

The #9600 operates it's 2 inch valve by battery, so no power is required. Each unit also features a separate 1/4 inch sampling point for bacteriological sampling or chlorine residual monitoring. Custom configurations are also available, including pressure recording and traffic breakaway.

Kupferle #9700 Automatic Hydrant Flusher

The #9700 Automatic Hydrant Flusher attaches to any 2 1/2 inch NST nozzle, either on a fire hydrant or flush hydrant. This portable unit weighs only 25 pounds and provides instant automatic flushing, with no installation expense. The #9700 features the same controller and flushing options as the #9600, so controllers can be inter-changed.

Featuring a powder-coated enclosure available in customized colors (red and yellow standard), the #9700 flushes the water softly through it's perforated lower grate, or water flow can be diverted by connecting directly to it's 2 inch FIP outlet. Many Kupferle customers have used the #9700 as a temporary flushing point to keep the water flowing in low-demand areas, such as new water mains with few service connections.

One of the many advantages of automatic flushing is also the ability to flush during the early morning hours without sending a crew. Both Kupferle units can be set to flush during these times when demand is low. Customers will not experience the discolored water sometimes caused by daytime flushing.
