INSTALLATION & USE

Installing Your Pentek Valve-In-Head Housing

  1. Mount the housing bracket securely to a wall or cabinet using appropriate fasteners, ensuring adequate clearance below for sump removal and cartridge replacement.
  2. Wrap 3/4" NPT male fittings with 3-4 turns of Teflon tape, thread into inlet and outlet ports, and tighten to manufacturer specifications without overtightening.
  3. Insert your chosen 20" standard filter cartridge into the blue sump, lubricate the Buna-N O-ring with clean silicone grease, and hand-tighten the black cap until snug.
  4. Slowly pressurize the system while checking all connections for leaks, then use the integrated valve-in-head to release trapped air before full operation.

What Works with This Housing

The Pentek 150166 accepts all industry-standard 20" filter cartridges with 2.5" outer diameter, including sediment, carbon block, pleated polyester, and specialty media from Pentek, Hydronix, Matrikx, and other major manufacturers. The reinforced polypropylene construction provides excellent chemical resistance across a wide pH range, making it suitable for municipal water, well water, and many industrial process fluids. Pair with 3/4" NPT brass or polypropylene fittings for seamless integration into existing plumbing systems.

🔧 Pro Tip: Always relieve system pressure using the valve-in-head before unscrewing the sump for cartridge changes. This prevents water spray and makes removal far easier, especially after months of service when O-rings can seal tightly.
