Question: Is it only my case or this filter makes noticeable noise like ticking about once per 2 seconds that can be heard in next room?
Document: I have 2 homes, one in Chicago with city water and a country lake house in Indiana with well water. For years I had been filling my own water jugs in Chicago and bringing them out to Indiana for the weekend. That was such a pain in the butt. So I found your system on the internet and it sounded like it would work for me. My wife just loves it. She decided to give me a blind taste test. We compared the Chicago city water to your system.
Then I reviewed my city water supply report for my area and it was quite disturbing. Living in Hawaii all my life it never crossed my mind that the water I was drinking could be filled with 1,2,3-Trichloropropane, Arsenic, Barium, Chromium, Nitrate, Simazine, Sulfate, Bromoform, AND Total Coliform.This is my 2nd system that I received from APEC. Sadly the first one I ordered had some water in the filter housing so I didn't want to take a chance.
Your system water just tasted like water. No smell, no weird taste. My family are all union workers and we always buy American when given a choice. Thanks for a great product.
It is really good  system you can install in your basement you just need more pipes, good water flow, water test is just like bottle water. Good think about this system is made in America.
The system has been working 6 weeks now -- we have chlorinated pond water with a system pressure of 50 PSI. The permeate pump uses excurrent water pressure to raise the pressure across the membrane. This is a dramatic improvement over the passive system it replaced. We now have much better tasting water delivered at greater pressure. Annual filter replacement costs are reasonable. All in all, a winner. Buy it.
I thought I was doomed to a life of water delivery and ice runs, or worse, buying another home. Your product and the Reverse Osmosis technology is fantastic. The installation was simple and having a non-electric permeate pump has helped save me the hassle of me installing an electric outlet underneath the sink. The pump really works too as I can hear a tiny clicking noise when it is purifying the water.
We had a RO system that was serviced by a water company for years. It broke a couple months ago. My husband decided to research different RO systems to purchase and install himself. After a lot of research we decided on the APEC Water High Efficiency system. Yes, it cost a little more than some of the others, but, it is so worth it!! The first thing we noticed is it did a superior job compared to the professional one we had.
My untreated tap water had a reading of 150 ppm and the purified water had a reading of 20ppm... Thank you for the great system and a flawless purchase and installation experience.
My husband said it was easy to install. We are so happy we made the switch to this system. It will pay for itself in a short time because of not having to pay for maintenance on the old system. All they really did was come to change the filters, which on the new one is easy. Oh, and the water pressure is great! I didn't even realize I had such poor pressure on the old one until I saw what we now have.
Just finished installing my RO-PERM system yesterday and I am extremely happy. Installation was straightforward and took me a little over an hour since I wanted to make sure I did it right. The tools required were very minor, a drill, a phillips screw driver and some wrenches.I did hook up my fridge to the system which only required some 1/4&#34; tubing and a quick connect T-connector from my local Home Depot at a cost of $12.
