All natural materials expand when heated and contract when cooled. The only exception to this rule is water. This unique property is called the anomaly of water. Water has the greatest density at 4 ° C, at which 1 dm3 = 1 liter weighs 1 kg. If the water is heated or cooled relative to [...]

Pumps for wells
As a result, subsurface pump having a length, for example, 60 cm, will have to establish a violation, if the water level of 1.5 m. CAUSE – above and below the pump should have at least 1m. It turns out that there must be at least 2,6 m – what do you do? There is [...]
Little Giant: Resuscitation of the well

Causes are different, and often easier to build new than to try to repair the old one. Restore water quality, of course, the pump [...]
