Culligan RC-EZ-4 Premium Water Filtration Replacement Cartridge for Under-Sink, Refrigerator, & RV Systems - EZ Change Water Filter System (500 Gallon Life)

UPDATE Sep 2019: It's been more than a year using the SAME CARTRIDGE. Our water processing plant is currently having issues with the quality of water and its coming out of the pipes very dirty. Using just the BASIC cartridge, the water comes out crystal clear, drinkable. This baby is amazing. Still no leaks whatsoever. Buying another replacement cartridge now just in case. Oh, the nut that tightens the unit to the sink broke because its plastic. Just buy a steel nut and problem solved. Should cost you like 3 dollars. ------------------------------------------------------------------------------------------- ORIGINAL REVIEW: After reading the reviews on this, I was skeptical. Some people said that the filter was not of enough quality or that it would not filter the necessary impurities. I considered that we live in a metropolitan area where the city water is just about decent. So we went with the basic filter option. Also, a reverse osmosis system is very expensive and wastes a ton of water (about 3 gallons of waste per 1 gallon of drinkable water). I have to say the results are amazing, even with the Basic filter: - No solids or visible impurities in the water. This means no "floaties" or "flakes" which is the way people refer to the calcium, manganese or magnesium precipitates that can be seen in cold or room-temp water. Although these precipitates are harmless (they in fact occur naturally in other foods we eat), they taste funky and look rather discouraging to drink. This filter took out all of that. - The taste of the water is great. Even at room-temp, the water is easy to drink and delicious. - the water pressure is quite nice with the basic filter. (see pictures) As for the installation, just follow the instructions and a few Pro-tips: PRO TIP: The mark included in the white silicone tube is 5/8 inch long. When you cut the tube to your liking, go ahead and mark the other side so you'll have no trouble fitting it to the right depth. PRO TIP: If you need to drill the extra hole in your sink. It will require the 9/16 bit. I tried the 5/8 hole as mentioned in the instruction, but the white tube does not fit. Use these to drill the hole: - TEMO M35 cobalt 9 size double flute step drill 3/8" shank 1/4" to 3/4" - CRC 03400 16oz Truetap Cutting Fluid Heavy Duty - Starrett 117C Center Punch With Round Shank, 4" Length, 1/8" Tapered Point Diameter You can check out my reviews on these 3 tools as well, for more details on how to use each for this application. PRO TIP: DO USE plumber's tape (the white one) on all male fittings. This will ensure no leakage. PRO TIP: when i first turned on the water, nothing came out. This was because the filter needed to click TWICE when tightening it in. Just make sure its nice and tight. Installation observations: - No leaks whatsoever were observed. A few people have complained about leaks, for us, this was not the case. We did use plumber's tape. - The process was very straightforward. Took us more time to clear out the area under the sink, than it took to install. - We left the filter loose (did not mount with screws) to be able to take it out and replace it easier.

I purchased this to replace an inline filter installed by my plumber two years ago. In order to replace the filter he had installed I would have to go down into the crawl space under my condo which is a long trip through three fire doors which starts in a full basement and ends under my place which is a dark crawl space about five feet high where the shut off is. Then I would have to go back upstairs dissassemble the filter, unscrew the compression fittings and then go back down under to turn the water on and hope nothing was leaking when I went back upstairs. Needless to say I didn't change the filter until it clogged and the icemaker stopped working. This gem took less than 10 minutes to install start to finish, including mounting, and I never have to make that trip again to change a filter. I have copper tubing that comes up about 10 inches out of the floor and from there plastic tubing is joined which ran about two feet to the existing filter and then there was about three feet of plastic tubing running from the filter to the fridge. I took a chance and did not turn off the water. Using my garbage can to catch any water I cut the fridge side of the tubing from the existing filter and a bit of water drained out. I inserted this cut end into fridge side of the new filter housing. I then (holding it over the garbage can) cut the water source side of the tubing from the existing filter and quickly inserted the tubing into the new filter casing. The cut wasn't clean, water sprayed out and the tube was not secure, so I removed it made a clean cut and reinserted - perfect. About a gallon of water ended up in the garbage can between cuts. I mounted the casing with two self drilling drywall anchors and secured the tubing into a foot diameter circular return with a twisty tie. It's working perfectly, no leaks, and the icemaker is once again making ice. I'm thinking of replacing my undersink filter with one of these when I use up my filters, it's a good filter but the housing has to be cleaned with bleach and it takes about a half hour to clean the houseing and change the filters and this is just so much easier, just unscrew the filter and swap it out. For the price this is terrific!

Fairly easy to install. I didn't have any leaks. Water comes out cloudy at first but then clears up as it settles (I guess from going through the filter media). Tastes a little different than before, but maybe that's because I'm used to the chlorine taste that it previously had and now it has no taste?. Overall, very satisfied. I did call tech support for a question on how far the tubing went into the culligan faucet (5/8 inch or all the way which is about 2 inches) because the manual wasn't clear here (just said to push 'firmly' into the faucet). The tech did not call back until the following day, but said it only goes in a short distance so the ferrule compression ring compresses on the tubing where the T insert is fitted into the end of the tubing. Makes sense to me...the insert gives it strength so the compression washer doesn't crush the tubing. I originally had the tubing pushed all the way into the faucet and still did not have a leak. Another thing I did was to cut a piece of 5/8 inch plywood to use as a template that I could hold firmly against the wall to drill the hole in a granite countertop for the faucet and to keep the bit from walking. I drilled a 5/8 inch hole (same size as the bit I was using to drill through the granite countertop) in the plywood where I wanted the hole and used it to guide the diamond coated bit to cut through the countertop. This worked perfectly. I kept dipping the diamond coated bit in water every 30 seconds to clean it and keep it cool. It only took about 5 minutes or so and I was through. Perfect clean cut.

great filters for the price that is why i buy them on sale, use camel camel camel and when the price drops i pick a few of these up and i am good for the year. I bypassed the fridge cartridge and plumed this baby in and saved some money for the life of the fridge.

Bonjour, l'article était bien emballé mais ce n'était pas compatible avec le système de filtration que j'ai.

Donne un très bon goût a l eau..par contre kit sans raccord pour le branchement...dommage
