The right Carbon Block Filter
I just replaced the 20" Iron Filter and the 10" Carbon Block Filter for the first time in my house. The Iron filter housing had the part number witten on it so I know I order the correct filter, but the 10" housing just said carbon Block Filter on it.
I ordered the Ametek, Culligan CBC-BB American Plumber W.5CBHD (CBC-BB)
.5 Micron, and we have noticed our water pressure is a lot lower, I'm thinking I should have ordered the Ametek GAC-BB, American Plumber WGCHD GAC Filter (GAC-BB) 20 micron.
Does think make sense, they they both have a 4 GPM flow rate.
