I purchased the whole house
I purchased the whole house RO system (4000 GPD) from US Water Systems a little over a year ago and it has been excellent. The system works exactly as advertised, and I have clean, great-tasting water throughout the house. My water was very high in salt and it doesn't taste like saltwater anymore. A bonus is that my faucets and appliances are no longer corroding! Installation was straightforward, and the build quality is top-notch. Their customer support has also been outstanding—knowledgeable, responsive, and very helpful any time I had questions. I’m very satisfied with both the product and the service, and I’d highly recommend US Water Systems to anyone looking for reliable water solutions.
