So here is my final review. We had some confusion when the product was originally shipped. I received the wrong size tubing when I ordered. Nick from iSpring sent me the right ones quickly. They arrived quickly and I finally had my system installed. I'm happy to report that the system is working properly and I don't notice any significant drop in water pressure (we have well water). Nick was a pleasure to deal with and I'll admit that I was unnecessarily annoyed with the hoses at first. He was very professional from the start. Very happy with the system and support in the US. I highly recommend this system! I will try to remember to update the system when the first filter changes appear in the system. Annual update: I changed the filters twice. Never had a problem with pressure drop. The sediment filter catches a TON of dirt. The activated carbon filter eliminates odors (the odor difference between the incoming pipe/sump and what comes out of our faucet is the difference between day and night). Were just satisfied. Highly recommended!
