Looking for a replacement unit - the one we have is about 6 years old and developed a pin hole le...

Asked by GaryB June 2, 2020

Hi GaryB, I had same thing happen about 5 years ago. Called GE support and they told me that chemicals in tap water can slowly degrade the plastic over years of service causing the pinhole leaks you and I experienced. So now I change the filters every 6 months and change the filter system/housing every 5 years. I recently looked around for alternate brand/model filtration system and the most reasonable one was Culligan model US-600A. I actually ordered it but upon receipt discovered that the incoming/outgoing water connections are plastic hoses simply press-fit into the housing inlet/outlet holes (there's a one-way clamp and o-ring inside to hold/seal the plastic hose). I really didn't like the idea of plastic hoses press fit into couplings - I can imagine the hose popping out and ending up with a much-worse-than-pinhole leak. So in the end I returned the Culligan filter and purchased this same GE model again (on my once-every-5 year schedule) because it uses very solid screw-in fittings which can be connected to the metal-braid reinforced water supply hoses. I'll probably by this same filter housing again 5 years from now, even doing this I think it's an overall better value than most other filtration systems. Hope this helps! LRC

No question just the same complaint as everyone else! The filter does not let you screw the capsule on tightly enough.

Asked by Ryan May 12, 2020

Hello Ryan - Thank you for reaching out about your filter. We are sorry to hear about the issue with changing the filter. If the casing will not screw on completely, the filter cartridge may have been installed upside down. Please let us know if you have any more questions. - JB

What comes with the filter housing? Parts, filter, etc. Thanks

Asked by John February 28, 2020

Hi John - A mounting bracket is included for easier installation. Compatible filters FXUTC, FXULC and FXUVC sold separately. Also, Sump Wrench (UCWRNCH) and Chrome faucet (UNFCTBL) sold separately. We suggest viewing the Installation Guide at the following link for complete details or simply scroll down the page to Info & Guides: - Thanks for choosing GE Model # GX1S01R. Keep in touch at Sue

how do you unscrew the top to replace filter

Asked by dude February 12, 2020

The top is mounted but the bottom simply unscrew by hand.

GX1SO1R water filtration unit is too small for all the filters that are supposed to fit. Why?

Asked by SV September 27, 2019

Hi sv - For FXULC and FXUVC filters, make sure the black seal that is at the top and bottom of the old filter is not stuck to the head or canister. The new filter has the same seals and doubling up even 1 side (top or bottom) can keep the filter from fitting correctly. For further assistance, please contact our SmartWater line at 1-800-952-5039. Keep in touch! Sue

Sump will not seal with filter installed.

Asked by Victor August 17, 2019

Too much talk from GE about the "Black seals" and not enough about the fact that the GX1S01R was made too shallow to accept "any" of the "C" style filters. I confirmed this at a home depot store a few days ago

I’m having an issue getting it to seal .... i bought the recomended “C” style.

Asked by Merks24 August 12, 2019

Make sure you check the filter seat is centered in the top base. This is a tight fit on purpose to seal. Put the filter in the base with the bottom bowl semi together and make the filter fit to the top base first and slid up the bowl and thread on by hand. Then use the spanner wrench to tighten. it will take a lot to get it to seal but it will seal. You may feel your going to break it but it should not. Its worth the results of clean water.

I dont think its filtering. THere's no pressure drop like before.

Asked by Ts June 29, 2019

If it was originally installed correctly, it should be filtering. I would not concern myself with pressure drop, unless the pressure is an issue at the output faucet. ALL FILTERS will have dust from what they re made of either carbon/charcoal I think the filters actually got larger (not shorter) because of the brute force needed close & compress the rubber seals inside the filter with/without wrench - Personally I don't think you should need to apply that much pressure to close/open the canister

Defective design period.
Hooked everything up according to instruction. Ran it for about five minutes or so to clear out the line. Checked for leaks; everything fine. Wake up to flooded kitchen floor. Huge leak coming from the filter compartment. No matter how much it was replaced and tightened; it still leaked. Bad. DO NOT PURCHASE!

Get all the parts!
This housing comes with mounting screws and nothing else. You'll most likely need 3/8 NPT fittings and a hose to run from the supply line to the housing, and use the existing line from the faucet to the housing. Also have some of the recommended silicone grease on hand for the filter o-ring gasket (making it slippery avoids leaks by dragging the thin o-ring). Assemble fittings and hoses to the housing and supply line before mounting and it's all easy.

Fine for what you pay for.
Got stuck installing this on New Years for my mother who didnt want want a double filtration system and didn’t want expensive replacement cartridges either. It didn’t come with the connectors so I included a photo of the brass fitting we used. It was obnoxious to install in a tight place and I had to tighten some of the connections after I hooked it up. Pros: Cost of the unit and filters. Cons: The brass connectors I used (once tightened) made it impossible to tighten the supply line as the nut was too close to the housing of the unit. Connect your supply lines to the brass elbows first, then screw the elbows to the unit. I STRONGLY suspect an oil strap wrench (nylon webbing kind) will be needed to replace the filter in 6 months. Note, this is not a verified purchase as my mother bought it and it’s not linked to my account.

dont buy it
Bought housing and filter and after few months went to change the filter.. Thenew filter is longer and will not let the unit seal. I thought i had a defective filter returned home with a new one and again the replacement side by side is 1/4 inch too long... save your self the aggrivation and move on to a better unit.. I have to see if Hone Depot will refund my whole purchase now a few months have past.

I gave this a 5 star only after a lot of sweat and toil. Originally installed and leaked like a sieve. The rubber gasekets are too thick, at least on the filter cartridge I also purchased. Called GE and they advised returning, but I wasn't ready to give up. I was fortunately having available some neoprene rubber to cut some custom gaskets less thick than the ones supplied with the filter. This is basically a good product but GE doesn't seem to have a clue. You need thinner rubber filter gaskets to allow a good seal to the O-ring between canister and upper housing. My unit, now with thinner gaskets, seals well. Be careful, you do need adequate filter rubber gasket thickness to ensure the water supply is not by-passing the filter and is going through it. I really feel GE owes me some compensation for all the work and experimentation I've done !!
