Review on Filter under the sink Geyser Prestige Smart by Adam Pietras ᠌

I connected it in the country, the pressure is 3.5 atm, the water does not flow. All night the drain gurgled into the drain, not a drop of water. I thought filters. All changed to new ones. The situation is similar. Not a drop. I bought a pump, also a geyser one, connected it according to the attached instructions. Again, not a drop. Invested twice. And it's all for nothing. Before that, there was the Allegro Geyser. Worked without a pump without problems.
