Clogs up quickly, unbearable flow rate
931629
We've had our refrigerator for 2 years, and probably bought around 5-6 of these.  As soon as you install it the flow rate of water is at least cut in half, and after around 2 months the flow becomes completely unbearable, ie minutes to fill up a reasonable sized glass from the refrigerator.  This is with a 3 person household.  Frankly I'm surprised everyone else rates it so high unless there is something specific about our usage causing this to clog up so quickly.  But I had the city water tech check our pressure (60PSI out of a spigot), and he also didn't think there was anything particular in our water that made it extra hard or contained anything that should cause an increased rate of clogs.

This unit worked amazing for the first 20 min it was in the tank, very shortly after that the flow rate dropped dramatically and now the water hardly even flows out of it. ive tried taking it apart and cleaning it, nothing appears to be clogging it at all....i don't know whats wrong with it.....

Filling the filter is not hard just 5-10 minutes of work but after two days it clogged the filter.

The new granules are too small and they collapse together on bottom which leads low water flow.

I returned the remaining two after I realize the clogging issue. I replaced the item with the original filter with the case

Gets clogged way to easily. Basically this thing won't pump. Boo.

The water drains out all at once and I have to clean the mud out of it each time I refill it. It isn't really hard to refill but it's not exactly easy either. I've gone back to watering my ivy from a measuring cup.

I'm STEAMED! This is my 2nd purchase of the General Wire Spring KR-A Kinetic Water Ram, my original was stolen from my truck. I spent 7 yes count them 7 years to clear this slow drain by plunging, and with your General Wire Spring KR-A Kinetic Water Ram took 3 pumps, and BLAM! clog cleared. Not even 10lbs of pressure. Note: If you buy this item, make sure you seal off the over-flow, other wise you'll get black gunk spraying everywhere.

Lost one star due to increased amount of maintenance needed as time goes on, Filter clogs quickly to. The filters are expensive for some one on my salary so that kills me.

Does what its supposed to, water tastes better than it did before, but the flow is SOOOOO slow.  It takes a full minute and a half to 2 minutes to fill up a 12 ounce glass, and thats with the faucet on full-blast.  I guess this is a side effect of the design.  Speaking of the design, its also big a bulky, a pain in the butt when it comes to washing dishes if you have a smaller sink.

If you have the ability to drill some holes, I would highly recommend checking out the Culligan US-EZ1 instead (http://www.amazon.com/Culligan-US-EZ-1-EZ-Change-Undersink-Filtration/dp/B000THIZUG/ref=sr_1_12?ie=UTF8&qid=1432493612&sr=8-12&keywords=culligan+filter).

The US-EZ1 has a significantly longer filter life, comes with its own mini-faucet, and ends up being a lot less expensive over the long run (1.2 cents per gallon vs the FM-15A's 11 cents per gallon).  I rent, so unfortunately couldn't drill the necessary holes in my countertop, but I'm regretting the fact that I didn't take a risk and just do it.  The Culligan FM-15A is a disappointment.

I would not repurchase this product, although it does a fine job. I've owned this for a few months now and get frustrated that it takes soooooo long to filter the water. It also is impossible to fill the main water compartment completely because the blue filtering section is smaller and takes a long time to create space.

Tons of water pressure without the flow restrictor and strainer. Loud pipe in wall due to increased GPM. Installed flow restrictor and o-ring/ strainer. Turned water on and no more loud pipe however, both pieces desintegrated instantly. Removed to find the above named parts completely separated and clogging the main oriface. Cleaned out all the failed parts and reinstalled. New teflon tape, and it's back to flowing amazingly. I'll trade the loud pipe at 5am for an amazing high-flow.

The fluid, of whatever kind, merely trickles from the spigot on this thing.  To fill a 12-oz. glass will take one full minute.  I only used it for water and iced tea, so there were no blockage issues.  I also inspected the spigot to see if there was a manufacturing defect.  Nope, it's just a trickler.  Making matters worse, there's no air flow from the top to provide pressure.  I took to taking the whole top off to get some sort of flow through the spigot.  It doubled the rate, but even that was completely insufficient.  Out of frustration, I just stopped using the spigot altogether and started pouring the tea out of the top.  What's the point of a spigoted jug at that point?  So, this $30 jug is now a glorified and unwieldy jar for tea.  Meanwhile, I bought an old cheapy for $5 from the local drugstore that works like a champ.

You can pour more water from a bottle faster than this hose will flow!  Works okay if you're not actually in the need of normal garden hose flow or pressure.

While this skimmer works very well the filtration media it comes with clogs very quickly which in turn stops the skimming. Even after changing the filtration media it still clogs. It seems as if the pump is too powerful for the dimensions of the skimmer. I haven't found the right media that won't clog yet, but when/if I do I will rate this skimmer higher.

***UPDATE***
I found that by shaking this stuff vigorously, mixing it with a little extra water, and using it in warm weather, I didn't experience the clogging problem described in my original review. As for its effectiveness, the jury is still out.

***ORIGINAL REVIEW***
This stuff is useless. It's so gunky that it clogs the filter on my sprayer every 20 seconds, even after endless shaking. It's a nice commercial sprayer. Not sure how this stuff got good reviews, but stay away from it.

Water basin fills up in an hour and needs to be constantly dumped out. Wish I could return it but it's too large to ship back.  Absolutely wouldn't buy again.

I've supported the company for about a year now. The filtration system is great. I seem to need to order a new one every month. Thats $50 a month! I probably contribute to their economy more than most reviewers on this page. Something doesn't seem right with the filters. Either the water is SO bad it starts to clog after a short amount of time, or this company isn't designing good quality filters. The filter starts to clog after 2 weeks, and takes 2-3 hours to filter out. It's frustrating.

I received a new one on October 11th, and it filtered quickly the first week. Today's date is the 26th of Oct, and its taking about 2 hours to filter out the amount I poured in, filled to the brim. I did what the company suggested to do in case this was an issue (which is probably suggested to do after a good amount of time): To re-drain the filter using their tool that holds on to the faucet. But it didn't work.

I'm really disappointed.

Significantly reduced water flow after installation. Will NOT buy this brand again.
