Slow water flow from GE SmartWater under sink water filter.

Suddenly experiencing slow water flow from GE SmartWater under sink water filter (dual FQSVF filters). Tried replacing filters. Little improvement. Water pressure in the rest of the house is normal. Any suggestions?

    Exactly the same problem with GE single filter under sink system. My guess it's something with air inside of filter

  • cbrogers551 Apr 27, 2009

    under skin water flilter never had as severe low pressure as now. change filter still low pressure . gx1s01c filter fxutc. what are the cams you are speaking about.

  • Corinne Sep 29, 2012

    Just reread the entry regarding air inside of the filter. I had another set of filters and replaced the new ones with this other set of new ones. Voila! Fixed. I think the first set of new filters somehow got air inside the filter and they didn't work. Thanks!

I solved the problem! The system's manifold (the plastic base you put the filter in) has small black conical shape button. When you tight the filter in, one of the two small triangle-shaped cams (located close to the filter's central hole) pushes the manifold's button, and this opens the water flow. The problem is that the cams are too low and do not push the button all the way in. Take a pliers and squeeze (not too much!) the cams, so they will raise a little: it will be enough to push the button to open the flow completely.

    I have the ge consumer and industrial single stage under counter filtration system
    Model # GX1S01R
    Internet # 202073861
    Store SKU # 186457

    What I did was drill the little pin holes (one on each side) with an 1/8 drill bit.

    This made a drastic difference. I then used a 5/32, and it was not much better... I think I am going to try a 1/4 inch drill bit next time to really get better flow... If anyone has any opinions about this, let me know!

  • tomyurkiw May 08, 2011

    Yes that was exactly it. Thank you.

  • Eugene Vosko May 08, 2011

    Where did you drill the holes?

  • Corinne Sep 29, 2012

    Can see the little cams no problem. They appear to be pushed in quite far. I just tried to squeeze them and it seems to have made the situation worse. Do you have to squeeze and pull up at the same time? Any additional explanation would be most helpful. Thanks!

  • Corinne Sep 29, 2012

    BTW, the water comes out quite forcefully at first, then reduces to a trickle. Does this tell you anything about how to troubleshoot? Thanks again!

  • Corinne Sep 29, 2012

    p.s. I just changed the filters

No, its the cams are too short. I thought GE had good engineering and manufacturing processes. Too bad this wasn't 6 sigma quality...

Like section 31 hq said it is just a valve so you wont have to turn water off. i just pushed the plunger up and wedged a couple of toothpicks to hold it. regards, macgyver mick

    This works temporarily for sure. I am sure drilling it out altogether will also work. Squeezing the triangles, not so much I think.

    Just remember to shut off your water valve when changing filters each time.

I drilled the valve out. It is there as a secondary "fail-safe" in case you forget to close the water valve before changing the filter. I always close the water valve before changing the filter so it is not an issue for me. Full water flow now.

    To clarify: I drilled the conical (black) water valve at the base where you screw in the filter.

The new filters are the same as the old ones provided with the system itself when new. The cams are the same height on both sets. Rather, it must be an issue with the micro-valves themselves.

    You couldn't be more wrong. There are minute variations in the cams on the filters. I currently have three filters that only give a slow trickle of water and a fourth one purchased at the same time that gives full water flow. If the problem was the valve then the filters would all behave the same.

  • Frank Farkle
    Frank Farkle Mar 17, 2015

    Yes, minute, of course, as it's a manufactured product. I still have my old system, and the filters are the same as the originals in my area. However, since that post, I've found that said variations and the cams themselves may be completely bypassed by inserting either #4 or #6 solid-brass screws into the valve openings, and so to open them up permanently. Of course, the " convenient" replacement feature is defeated, and the water must be shut off each time the filter set is replaced. Got water?

Water filter drain running all the time


Is this a new system? The should be a small restriction in the drain line. The size of the restriction is matched to the gallon per minutes of the R.O. system. Yours could be missing or not the right size, ie not enough restriction.

GE Smart Water under sink dual water filters replaced. Very little water pressure. I have reinstalled them, no improvement. I have been replacing these filters for 5 years and have not encounerted this...


Hi jbboggeri,

Welcome to fixya!

I would go ahead and open the new set and install them. If you get pressure, you know the others were bad and can send them back for a refund.
If there is no change, you can always put them away and use them again later.

Please reply back and let me know how it went. Thanks,

I have a smartwater filter (model GXRLQ) under my sink and when I changed it, it began making noise like air was in the line. After the noise stopped, the water is barely flowing. Any suggestions?


If you were simply changing the filter, then I would pull the new cartridge back off and inspect the o-rings. It's possible that one got bunched on the install and is blocking the inlet/outlet of the water. Other wise if you had to turn off the water any where to change the filter, check the valve that the water runs through to see if it is turned on all the way.

GE smartwater filter (model GXRLQR) stopped working...help!


These replacement filters (GXRLQR) are FLAWED straight out of the factory. The problem is in the 2 little "teeth" nubs that stick up near the center circle of the filter. When the filter is twisted and inserted, these teeth push up on a tiny black spring loaded valve in the body of the filter, alowing water to pass through up and out the spigot. The flaw is that the "nubs" are too short and do not push open the spring valve far enough, reducing flow to a semi-trickle, even with a brand new filter. GE seems to think this is not a problem.

Solution=stick a $0.25 garden hose rubber washer in the top of the filter and screw it in. You may have to try a few times to get it to work and seat properly. When it works, you'll immediately get a nice super flow of water. Better than upgrading to a $200 filter system recommended by GE...

Low water pressure is diminished after replaced 2 filters in a month. plumber tested to see if water is fully flowing.


Does this mean that you are now having the right pressure? Since the filters are changed, water should
now flow. Is it all systems go?, that is assuming that
your pipelines are not clogged.

GE SmartWater RO Filter Tank Leaking?


I had same system under my sink for same amount of time and have since then removed entirely for health reasons related to Ro Systems. Mainly the tanks becomes contaminated [alge build up]and my faimly had constant nagging stomach aches which took a long time to resolve untill we decided to disconnected and throw out our "beloved healthy RO System" and decided to install a bi annual disposable type filter system. If you are expereanceing this I would advise the same as for the leak ,There are so many connections under there and it is usually not the tank but the fittings in lines some where and the reason it looks like the tank is because that is the lowest point the leak has traveled. So check all your fittings and if you decide on simple water filter I will advise you.

Please rate. Thanks jj505
