Hi Diego Now what you should control is the supply network pressure. At this time and according to the area, there is little pressure. How to control Well, connect a hose to the inlet and check the water column as far as it goes, raising the hose gradually until it cuts you will have an idea of the existing network pressure. I guess the pump is connected to a cistern. If it is not and it is connected to the network (in some areas it is prohibited) the same pump will take away pressure. Regards
