The Pentek 150235 is a complete whole house filtration system manufactured by Pentair/Pentek, designed to provide point-of-entry water filtration for your entire home. The system includes a Pentek #10 Big Blue heavy-duty filter housing (Pentek 150235), a mounting bracket, a housing wrench, and a Pentek DGD-5005 dual-gradient density sediment cartridge. With 1" FNPT inlet/outlet ports, it handles flow rates up to 8 GPM, making it ideal for reducing sediment, dirt, sand, silt, and rust throughout your home's water supply.

The Pentek 150235 system ships with the Pentek DGD-5005 dual-gradient sediment cartridge, which has a 5-micron nominal rating. Its unique dual-gradient design captures larger particles on the outer layer and progressively finer particles toward the core, resulting in significantly longer service life compared to standard single-density sediment filters. This makes it highly effective at trapping sediment, sand, silt, rust flakes, and scale particles before they reach your home's plumbing and appliances.

The included Pentek DGD-5005 cartridge typically lasts 6 to 12 months or up to approximately 20,000 gallons, depending on your incoming water quality and household usage. Homes with high sediment or well water may need more frequent changes. A clear sign it's time to replace the cartridge is a noticeable drop in water pressure throughout the house. Regular replacement protects downstream appliances, water heaters, and fixtures from sediment damage.

Yes. The Pentek 150235 Big Blue housing is tested and certified to NSF/ANSI Standard 42 for material safety and structural integrity. The included Pentek DGD-5005 dual-gradient cartridge is also certified to NSF/ANSI Standard 42 for mechanical sediment reduction, ensuring the system meets industry standards for performance and safe drinking water contact materials.

The Pentek 150235 installs at your home's main water line (point-of-entry), typically after the main shutoff valve and before the water heater. Key specifications include: 1" FNPT inlet and outlet connections, a maximum operating pressure of 90 psi, a temperature range of 40–100°F, and dimensions that accommodate a standard 10" Big Blue cartridge (4.5" x 10"). Professional installation is recommended to ensure proper sealing, bracket mounting, and bypass configuration for easy future cartridge changes.
