I am a 60+ year old female, with an arthritic right hand in a 1931 bungalow home. Anyone who owns an old home knows there will always be the unexpected lurking when working on the house - so I went into this project anticipating a few hiccups. Since I was going to be working in the kitchen, I decided it would be a good time to put in a new sink with larger basins. I also upgraded to the APEC Ceramic Disc Designer faucet, which turned out to be the most challenging part of installation despite the fact that I mounted the faucet prior to setting the sink. The ceramic disc faucet is definitely worth the upgrade because it has a heavier/sturdier feel. Faucet installation would have been a breeze had the instructions been clearer and not so intuitive. But after three attempts - it is nice and secure !
I have never worked on my back, in a cabinet, under a kitchen sink. Despite this disadvantage/learning curve; installation of the APEC Reverse Osmosis system was a snap and took no time at all and thanks to the very thorough instructions, online videos, and "common sense" manner of the design. When I turned on the water supply, the first housing had a steady leak. I called APEC and was speaking to a real live person in less than 15 seconds. WOW !! Assured it was probably a missing O-ring (a quick glance proved it was), I was promised a replacement would be sent out ASAP. A confirmation email immediately appeared in my inbox including a tracking number for the shipment. WOW Again !! (Thankfully, later that evening after calling APEC, the "missing" O-ring was spotted under a kitchen stool and the system was up and running ... leak free in minutes.)
As instructed, I emptied the first 4 tanks of water and it has subsequently been a wonderful first week enjoying delightfully crisp, delicious, clean water right from a sink faucet. I did not test my water as many other reviewers have done. APEC's great reviews and the taste of my water was proof enough the system was making vast improvements to my tap water quality.
I have already recommended the APEC Reverse Osmosis systems to several co-workers and my son will be receiving one soon as an early holiday gift. If you are on the fence about buying and installing an APEC water filter system, I can attest to the installation ease (assuming you have a good layout under your sink).
And if the product information does not immediately prompt you .... the APEC Customer Service definitely will. I cannot remember such outstanding telephone service since the 1970's.
