i use a 3oo RO with a diaphram pump 125psi, 1.2 lpm,   taking 1 hour to fill a 25 litre drum,   anyone any ideas what i could use to make it quicker.   ive no outside taps so have to make it in the kitchen 

  maybe a stronger pump,    ive not bothered taking tap pressure,   i will buy a pressure gauge , test it and sell it half price,wont need it when i know.
