in this video, I want to show you how to replace your three-stage filter for your pretreatment of
your under sink RO system so I have all my three filters right here so stage 1 stage 2
stage 3 so the first step is locate your inlet valve which is on my case this right here it's
the one that's feeding into your inlet and then also your pressure tank valve which is right here
and make sure that you close them it's a quarter turn then you want to make sure that your water
is drained by opening the valve on the dispenser this is a gate valve or plug valve I think right
now your system should come with a wrench this wrench is only supposed to be used for untighten
these housings and not for tightening them you can try hand untighten if it doesn't work then
use the wrench there we go now probably a good idea to put something underneath so that when
you leak water taking this off you don't make a mess carefully drain it as you can see my my
water is pretty good so it's got some dirt on it but it's not too bad as you can see it's pretty
dirty and disgusting on the inside so you want to wash the housing before installing a brand new
one before I install the new one I'm gonna remove this housing because that way it's out of the way
so it's easier to untighten and just work with it and then I'm gonna replace that one as well
there's my other filter Oh make sure to have a rag on you whenever you make spills you can wipe
him down looks like before I had in second staging just a block carbon filter that's probably because
I used to be on well water with a softener instead of an RO system so I needed that extra carbon to
get rid of the smell and for it to taste better so but I think I got this one from Home Depot a long
time ago shows that I haven't been maintaining the system again you can see that even in the second
one there's some garbage in there so this is the importance of replacing them more frequently so
that way it's caught on the front end and this last one yeah like slime on it gross it's my other
carbon filters I think this is a cheaper one that I had from Home Depot as well oh that's disgusting
yeah it's been a while since I replaced these apart from slime the the filter itself I mean
the housing itself is pretty clean in addition to cleaning the housings I would take a white
wet rag and wipe on the inside of each house each connection just to get rid of any particles or any
dry debris that's on it now that the housing is clean it's ready for installation so you see how
you have that Center holder thing in the middle right there well you want to put your filter
and align it down the center as best as you can't kind of let it sit in there also if you have leaks
a potential cost could be this o-ring so unless you just have didn't tighten it tight enough or
but typically could be that o-ring licking so then try to keep it centered okay one done remember to
always to just hand tighten so then the next one down the middle and last one again make sure it's
sent sitting in the center and that's it don't forget to turn on both of the valves and flush
the system for ten minutes thanks for watching this is how you replace your first three or two
stage filters on your reverse osmosis RO system that's under your sink comment share subscribe
