The scheme works with two pumps, jetting "brook"

I decided to improve the well-known scheme jetting and use it for erosion and the rise of soil on the surface. But instead of one powerful pump used two small type "brook." It's simple, unpretentious and reliable pumps, well-known cottagers. Also, many people know that they do an excellent job with the transfer of even the most highly contaminated water. It is this feature of the pumps, "brook" I took.

Scheme jetting with two "streams" is shown in Figure 2, and how to work with him next. Deepening a well in the usual way until the first water, continue to work for a few minutes. Once at the bottom will hold several buckets of water, you can proceed to work the monitor.

One of the "Brooks" delivers clean water to monitor the discharge nozzle (Fig. 2 and 3), the stream from which erodes the sand and stirred vigorously with water. Simultaneously, a second "brook", mounted inside the monitor case, the formed slurry pumps and delivers it to the top, gradually deepening pit. The main thing with this constantly monitor how the concrete barrel goes down. Movement should be smooth and strictly vertical.
