Pentek Big Blue Filter Housing and 20in Sediment Cartridge - Heavy

In this review the Pentek Big Blue Filter Housing and 20in sediment cartridge bundle is evaluated for whole-house and high-flow sediment protection. The bottom line: this bundle is best for homeowners or small commercial sites that need a large-capacity, durable sediment solution because the extra large 20in housing accepts a high-capacity cartridge and the ECP20-20BB media offers 33% more dirt holding life compared with standard cartridges. The package is straightforward to install for people comfortable with basic plumbing, and it makes a clear difference in reducing visible dirt, sand and particulates.

Key Features

• Extra large capacity: The 20in Big Blue housing allows for greater cartridge capacity so fewer vessels are required for high flow-rate or heavy-sediment systems.
• High-flow cap design: The HFPP cap with 1in NPT inlet and outlet supports higher flow and faster pressure throughput for whole-house service.
• Durable construction: The heavy duty housing and robust materials stand up to typical household plumbing and offer long service life.
• Sediment protection: The ECP20-20BB sediment cartridge removes dirt, sand, silt and particulates to protect appliances and downstream equipment.
• Improved dirt holding: The cartridge uses a resin-impregnated cellulose and polyester blend delivering about 33% more dirt holding media for longer life between changes.
• Chemical compatibility: The housing is compatible with a wide range of chemicals, useful for different water conditions and cleaning routines.

Who It's For

This bundle is aimed at homeowners, rental property managers, and light commercial installations that face heavy sediment or need a higher-flow whole-house filter. The extra large 20in housing is useful where longer cartridge life and reduced maintenance frequency are priorities.

Those seeking fine taste and odor removal or specialized media (carbon, KDF, or softening resin) should look elsewhere or plan to add additional vessels, since this bundle focuses on sediment removal rather than chemical or mineral treatment.

Pros & Cons

Pros

• Solid build and heavy duty housing that fits 20in cartridges for longer service intervals.
• Cartridge media blend increases dirt holding capacity and reduces change frequency.
• High-flow HFPP cap and 1in NPT ports support whole-house flow rates without major restriction.
• Generally straightforward to install for those with basic plumbing skills and protects downstream appliances well.

Cons

• Some customers report mixed assembly quality and isolated leakage issues, so careful sealing and checking of fittings is advised.
• Mounting hardware is not included, requiring separate purchase for wall mounting in many installs.

Frequently Asked Questions

Will this handle high household flow rates?
The HFPP cap and 1in NPT ports are designed for higher flow and will handle typical whole-house flow demands when sized correctly.

How often should the cartridge be replaced?
Replacement interval depends on sediment load, but the ECP20-20BB offers about 33% more dirt holding so it typically lasts longer than standard sediment cartridges under similar conditions.

Does the housing include mounting screws?
No, mounting hardware is not included in the bundle so plan to obtain appropriate screws or brackets for installation.
