Booster pump like Aquatec will give you full rated output, and reduce pass-thru solids by 50% (means the filter traps 2x more), less wasted water, even takes out chloramines w/ no residual nitrates. Use it with an electronic water level shutoff. If you have 80psi water pressure and 80F water temp year round, you don't need this, but it increases pressure to about 120psi to maximize the efficiency of the membrane. Its expensive, but will double the output and molecular trap efficiencey. Search words "Aquatec Booster Pump" then also check for electronic level switch on that site.
