Review on 💧 Enhance Water Quality with Watts Premier WP531105 Annual Filter: A Comprehensive Solution by Edwin White

I love the reverse osmosis water these filters produce and have been using this system for 15 years now. But lately the sump and pre-filter cartridges seem to be clogging very prematurely. And I live in a city with the best soft water in the country. I'm tired of replacing those expensive filters every 2 months and suspect they intentionally reduced filter throughput. So I installed a cheap CAMCO EVO filter in front of the system. This solved the problem. No deterioration within 5 months. And the original cartridge in the CAMCO filter still works great as a pre-filter and protects valuable Watts filters.
