Depending on how quickly necessary to make pumping, and is determined by the choice of model. Typically, drainage pumps made of stainless steel, but there is a valid and reliable models of plastic – for example, grundfos type unilift cc. Their main advantage – with respect low weight and price. In addition, such units are low noise and can be installed directly in the house. They are not too powerful (capacity not exceeding 3 l / s (11m3 / h), but this is quite enough for not too wet sites and occasional use – siphon drain well, pit, eliminating the consequences of small household accident. It is worth noting that such pumps operate only in relatively cold water (4 to 40 C) so pumped hot sinks, they can not. Choosing a pump, you should pay attention to such of its characteristics as a maximum size of particulate matter, skip the unit, or otherwise – on the diameter of the outlet pipe. If in specific circumstances can not prevent sludge, wood chips or plant into the water, you'd better have a pump that can pump dirty water with the dimensions of mechanical particles of 40-50 mm (eg, grundfos type unilift ar made of stainless steel).
Attention, drainage! In conclusion, we must give some tips on care and maintenance of drainage systems. Remember that once laid pipes, heavy equipment on site can not ride, and if topsoil compacted cars wheels, it should be deep tillage, to give the necessary degree of soil permeability. Otherwise, the drainage system will not work. The main causes of decline capacity of drainage pipe can become sludge pipes in some areas, damage to pipes, overgrown sections of pipes due to siltation and clogging, clogged holes in the filter cuts. Therefore, every 2-3 years drainage pipe preferably washed in order to prevent them from silting and clogging the holes iron hydroxide. To this end, the open edge of the reservoir (that flows into the water inlet) connected the hose and hosed water washed drainage system. Also, specialists are advised to use special hydraulic high-pressure equipment.
It is in organizations that have a corresponding "chalet" services. and important: remember that spring to spring is not necessary. And if you're lucky this time, and water was scarce, is it worth waiting for "surprises" by nature? After all, no matter how the climate is changing, the main way to combat excessive moisture has been and remains drainage. Press office of the company "Grundfos"
