"Installed ourselves and fits perfectly under our small sink. The pump motor does make a little noise while using but nothing too loud. Water tastes great!"
"Recently I replaced my old APEC Perm-90 with the new APEC ROTL-600 thankless system. The old system had given us many years of reliable service. The new system is sleek and thankless so there is no pressure tank taking up valuable space under the kitchen sink. It was easy to install and more efficient with 1:1 ratio of waste water to usable water. The older system had about a 4:1 waste to usable coverstion ratio. We live on an island on the coast of Maine and every drop of well water is precious so the 4 times higher efficiency is wonderful. The new system has been in operation for a month and we are very happy with it's performance. The only glitch I had was with the new faucet. The old faucet had a slightly larger diameter base compared to the new faculty. When I installed the new faucet it didn't quit cover the existing hole in the sink flange. The new faucet is definitely superior in quality to the old one, but the fit issue was a bit problematic."
"My wife’s been bugging me about getting an RO system and now she’s happy. Install was easy except the faucet install behind the kitchen sink which was a giant PITA but that’s a pain with any system. Waters great and I also added a cooler since the S. Florida tap water temp. is pretty warm."
"At first I was very happy and the water tasted wonderful. Difficult to install but then it was okay once in. However about 6 months into use the CF filter started blinking red and I read it was time to change the filter. After getting it shipped to me, the filter was sealed so hard that it was impossible to untwist and get it out. Spending hours and possibly calling a plumber to change the filters is unreasonable. There is some flaw in the design… it’s unfortunate as it was a great beginning"
"Best purchase I’ve made, I love it"
"We bought our first R/O machine in 2008 from APEC. Liked the system but it was a pain to change the filters or tanks. This time around we wanted to try the tankless in a house we are re-habbing. It definitely took the plumber longer than the few minutes stated. It also didn’t say it needed its own dedicated outlet in the paperwork. We had to call an electrician or put a button in the counter for the garbage disposal. The tank cycled and failed the first time during set up. We called CS again and they said to reset it. It took about 1. 5 hours to cycle through and then water finally came out. We haven’t tested it but it definitely taste better then the tap water where we live. There were cheaper machines on Amazon but they seemed unreliable. Price wise, it is mid-range but it seemed easier to get answers to questions vs dealing with Amazon sellers"
"Enjoying our recently installed system. The water tastes noticeably better and appears to be noticeably clearer."
"The simplicity of the installation and the taste of the water makes me wish I had done this years ago. I cannot recommend this system enough."
"Fantastic!"
"I can’t even find the power button on this thing. Also, I wish the worst in life for whomever chose to use a nut on the fitting that only has two flat sides."
