SeeSNIFTER & DRAIN BACK VALVESfor an explanation of these devices, how they work, where and why they are used on wells with submersible pumps and bladderless water pressure tanks. Often a shallow well line works well for years without freezing, until in particular we find a very cold winter...
These wells are usually installed close to the houses. Many of them are open or equipped with a makeshift cover. The water is drawn from the well with a bucket or a can cut-open with a rope. In this type of water supply system, the application of the various risk analysis methods ...

Water wells with inadequate capacities for the defined risk may be used to supply storage facilities, which then can be used to supply firewater systems through firewater pumps or from gravity flow from storage tanks. The capacity of well water source is dependent on the aquifer permeability, its...
The main methods of preparation of hot water for product curing are: the solar heat collector + air-source heat pumps + hot water tank set on the roof of recycled aggregate production workshop, with heating tubes inside the tank for auxiliary heating. The preparation of hot bathing water is...
