The sump is annealed (heat treated) to relieve stress, add clarity and increase strength. Pentek clear slim line housings offer on-site examination of flow, performance and cartridge life.

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.
