Yesterday I asked about my well pressure problem, and the consensus is I need to replace my filter cartridge.
The existing filter/cartridge have no obvious brand/model identifying information. There is a clear plastic container about 5 1/2 inches in height, and the cartridge inside has fine metallic windings around a cylindrical core, about 2 1/4 inches in height. Most generic cartridges I see online are 9 inches tall. There is a spring under the cartridge inside the plastic housing, and under the assembly there is a water release valve.
Any insight as to what type of filter cartridge I have, and where to go to find a replacement?
