I have had my NOVA system in my villa for over three years and no problems. When I moved to a larger home last year, the 1st call I made was to Bob who installed the system. He is one of the most knowledgeable persons I know when it comes to water and filtration. His system is top quality and I really like that there are 2 pressure gauges, 1 going into the filters and the other as the water leaves. I check the pressures every 2 months and when the difference is more than 5 lbs., I call Bob to replace the filters. This takes away guessing as to when to change!
Thanks Bob for your product and more for your service.
