Comment:
This is the second Aquasana under-sink filter system we had purchased - this one to replace the first one that cracked open and flooded our under-sink without warning. The second one looked to be an improved design, yet the same problem occurred - again flooding our under-sink after less than 5 month's use.<br /><br />Although we got about 2 years use out of the first one, the plastic screw-down cap that holds the filter in split at the threads and caused flooding under our sink and onto the hardwood floors before we realized there was a problem. We have normal water pressure - and it is additionally regulated with an a pressure regulator as it enters the house at 65 PSI static.<br /><br />In December, 2014 I replaced the product with a seemingly improved Aquasana 4601 system that after less than 5 months did much the same thing - this time the plastic threads separating from the cap - again causing flooding under our sink and onto the hardwoods.

Comment:
I have purchased 3 different variations of this product, both under counter & countertop. I have never had any of them leak. They have each given great service. I especially love the auto ship feature for getting new filters shipped every 6 months. You don't need to remember to order your filters, and you always have fresh water. No lugging gallons of water home!
How long have you owned it:
More than six months
Bottom Line
Yes, I would recommend this to a friend.

I have had several rage episodes trying to replace parts, spontaneous leaks, etc. Don't purchase this! Fine until you have to replace filter (every 6 months). Clean water is not worth this aggravation. Really aggravating! Avoid avoid avoid! From one very regretful customer. Buy bottled water! Save yourself from having a coronary!
