"Had to have a plumber install it, but for our needs it was worth it."
"This seems to be working well. I was surprised at the a tent of costs for the plumbing fixtures and pressure gauges. This was a substantial increase in the overall costs for installing my system"
"I gave this a lower rating because of how difficult it can be to order (not to mention how long it takes to get thru to a representative to help order) and how easy it can be to order the wrong item. Basically, I'm thankful I'm selling my house and won't have to deal with ordering from apec any more. Done."
"The good - the system was easy to install and works great. Give me peace of mind knowing that the water is safe and tastes good. The bad - after I ordered this it did not actually ship for nearly a month. I emailed after 2 weeks to find out why it hadn't shipped. It wasn't in stock when I ordered it. 2 weeks of waiting and it still wasn't in stock. There was no information on the site that it was out of stock. I would have ordered a different system from them that was available. It finally shipped 2 weeks after I called. I like this company and this is my second system and will use them again. I hope this was a glitch in the system"
"So far so good, The system works well, water tastes good. Wonder how long the water has to run to clean the new filters? And I also wonder if anyone here knows if softness hard water a little. Some?"
"Installed the whole house Multi Purpose 20 BB Sediment KDF and Carbon Combo Water Filter 7 days ago installation went well and the water flow did not reduce in pressure."
"Before installing this 3-stage filter system we had very very heavy iron and sulfur smell in our house. I installed the system myself. Pretty simple and straight forward. Very impressed with the quality of the system. After installing the filter system our water is iron free and sulfur free. I have already recommended this product to others as well."
"I installed this along with the Whole House Big DUO Housing Set with the 2 BB filters. I used the 2 as a 2-stage sediment pre-filter then it goes straight into this. We are on well water and have some issues with iron sediment small amounts of lead and hydrogen sulfide. I specifically wanted the KDF-85 filter and it seems to be doing quite well. The nice thing about the BB setup (5 stages in my case) is I can try different filter combinations if needed but not have to change out the housing. I should also mention that pressure drop across my 5 stages is not noticeable at any fixture and our pressure tank puts out about 54 psi. No noticeable difference in flow rate either. I am happy with this purchase and would do it again. We also have the RO-PH90 that further filters our drinking water."
