Question: how do you stop the o-ring lesking
Document: We've been using the under sink Aquasana for about 4 years now. Yes, it's a pain to change filters. I had to keep notes to remind myself each year to tap one of them on the counter to get it out after opening the casing, and it does take a little work to get the seal tight to stop leaking.
It was difficult to remove one of the two filters, but finally it came loose (I can't actually remember, but I am guessing that this was the one banged on the counter during the original installation). Unfortunately I found that this filter had come apart in the casing, and the top piece of it with the O ring was stuck in the case. I could not remove this part. It was incredibly frustrating.
Push down on each hose and then pull out while holding down the grey ring. I used a 11/16 socket wrench to break the seal on each. There was a little mold on the bottom of one side of the housing, or was it carbon residue? As you can guess, it is irrelevant. To be absolutely honest there was NOTHING to talk about, No odor, no sediment, no build-up, no gunk! Kind of disturbing actually. I'd prefer it WAS a mess.
We've had Pur tap water filter for cooking and used to drink Mountain Valley Spring Water via delivery. However, we had to stop the water delivery due to cost. My family (wife and 2 kids) hated Pur water filter's taste for drinking. I got this and did blind water taste and they all chose Aquasana for taste! While it may not be as good as Mountain Valley, it truly is great for its money.
The people who complain about the product cracking have high water pressure. My water pressure is neither high nor low and when the water comes out of the filter, it comes out slowly. But, im using it for drinking water and i dont mind waiting for it to do its job. Its good water. For those with high water pressure, get a more expensive product or lower the water pressure in your house, and stop complaining. Also the filters on the countertop one are easy to change.
I had trouble installing the product even though its not hard to do. I attribute most of that to user error, the instructions were fairly straightfoward though I kept thinking that the system didn't seem correctly installed. The company has a video on their website of how to install the system. I had trouble tightening the filter ring onto my faucet, perhaps becuase I was using a cheap wrench. Hopefully most people will do better then I did.2.
there are only two things i use to rate any product: dependability and quality. the aquasana filter has passed with flying colors on both counts. does not leak,or break easily. i really put this product through it's paces and it still works just fine. just make sure you follow the instructions and you will have no problem. as for water quality..the taste is actually better than bottled spring water.
sooner or later Aquasana needs to come up with filters casing people friendly. Its a shame that the majority of the people are unable to change the filters. Someone need to start a movement against Aquasana and the way is not respecting the water for life agreement by sending for free the replacement for casing that cannot be use any more
probably, but not a whole lot. Is it more economical? Barely. Does it do everything Aquasana says? Probably not because of....2. What are the filters made of? Basically the same as a PUR filter. After replacement I decided to tear one apart. The filter is Nothing but formed activated carbon. Both filters are exactly the same. I'm not sure why they mark them different, call us suckers??
Would be nice if they had a smaller capacity unit at a smaller price.Right now I need to buy a new unit since one of the filter casings is jammed and won't open. Broke the tabs on top trying to get it open. Did some research and it seems there are no other reliable products so until a company makes a better filter, I will order another Aquasana.
