With the tap to the water due to the pressure switch easy to put on and abstellen.Man does not have to operate a pump switch and through the long suction hose (remains with another non-return valve made the water seal. The laborious casting omitted. The ton is a jewel in the garden. Sprinkle lawns or shrubs etc pour has become extremely easy. Simply turn on the tap.
