The Pentek 153070 Big Blue Housing Sump for 20-inch Big Blue water filters has four times the capacity of standard whole house filter systems. Its industrial-strength design can handle high-flow applications and heavy-sediment settings. Plus, the sump size is adaptable; you can upsize or downsize your filtering capacity as needed. If you have a #20 'Big Blue' housing sump, you can replace it with a #10 sump, and vice versa. As an added bonus, these blue housing sumps are interchangeable with American Plumber, Ametek, Culligan, Pentek, and US Filter brands. If you need a replacement sump, this is a great option to consider.
