Report "The water pressure after I installed my GXULQ twist and lock filtration system wasn't great to begin with but the flow has decreased even more in the last week. I tried removing and reseating the filter, and the flow got even worse. Any recommendation other than buying a new filter and seeing if water pressure is higher? I wasn't able to find any other filtration systems that don't require a separate drinking water tap *and* fit under the sink in my tiny New York City kitchen"
