We purchased our systems 4 years ago. There are so many options when it comes to water softeners units and RO systems and my husband looked at them all and decided on Ecowater Systems. So glad he did. This family owned business has great customer service. I get a letter every year letting me know it's time for my filters to be changed. Brandon the technician that comes out is so nice and helpful. Our dog loves when he comes cause he plays with him.
