Aqua-Pure AP102T / AP102S and the CUNO CFS02T Valved Head models feature the Built-in shut-off valve with pressure relief buttons and are made from FDA CFR-21 Compliant Materials.The "T" and "S" suffix designates either a Transparent (clear) or Solid (opaque) sump housing. Includes a filter wrench.
Valve-In-Head designs relieves pressure for convenient cartridge changes: Turn to shut off water, then remove housing from head assembly.

Note: Clear Housing Sumps are more prone to leaking and cracking, and are not as resilient as their opaque counterparts. They may be significantly less able to handle high pressure, temperature, exposure to sunlight, and other stress. We highly recommend considering a black, blue, white, or grey opaque housing sump, especially if your system is operating under high pressure or temperature conditions. Fresh Water Systems offers heavy duty polypropylene filter housings in a variety of sizes and colors.
