Spec is 11.3 Liters PM. I never feel as though I have enough water pressure whether on the pump or city water. I just think the 1/2 inch tubing is too small. This week I installed an Oxygenics shower head after all the accolades on this forum. Heading to Vegas on the 18th and will test it out. By the wa, my pump was behind the basement of my 5'r. I cut access walls and replaced the 4 screws that held the wall in place with quick nuts so I can repeatedly take the panel off to get to my pump. It surely is a continuous learning process.
Best of luck
