link how to put membrane and housing together:
https://www.youtube.com/watch?v=iP0t25qn7HMensure you remember flow direction. use vaseline on orings, when inserting a membrane ensure that the side with no seal goes in first. do not drag the side with the seal through housing.
1/2 inch blanking cap goes on the supply side, 1/2 inch opening on the opposite sideof the housing is your product, the other one 3/4 inch is you waste.
how many filters do you have? if 2 20 inch ones: first one should be the one without casing, second with plastic caps in simple terms.
if 3: particle filter , gac ,block carbon in this order if i remember right...
