Technical Details

Manufacturer Watts
Model Number FH8000BL34
Housing Size 20 inches (for 2.5" x 20" cartridges)
Port Size 3/4" NPT inlet and outlet
Maximum Pressure 100 psi

INSTALLATION & USE

Setup & Operation

  1. Mount the housing securely to a wall or frame using appropriate brackets, ensuring the sump has clearance below for cartridge changes.
  2. Apply thread sealant tape to 3/4" NPT connections and install inlet and outlet plumbing. Verify proper flow direction if using directional filter cartridges.
  3. Insert your 2.5" x 20" filter cartridge into the housing, then hand-tighten the sump onto the cap with the buttress threads until snug and properly seated.
  4. Open water supply slowly and inspect all connections for leaks. Flush the new cartridge for 2-3 minutes before putting into service.
  5. Replace filter cartridges according to manufacturer recommendations or when flow rate decreases noticeably. Always depressurize before opening the housing.
COMPATIBILITY

Cartridge & Application Fit

This Watts Flowmatic housing accepts any standard 2.5" diameter x 20" length filter cartridge, including sediment, carbon block, pleated polyester, and specialty media cartridges from Watts, Pentek, Hydronix, and other major brands. The heavy-duty polypropylene construction and EPDM seals make it suitable for commercial water filtration, chemical processing, food service, industrial pre-filtration, and applications involving aggressive chemicals like acids, ammonia, oils, and plating solutions. Not recommended for pressure relief applications or temperatures exceeding 100°F.

🔧 Pro Tip: Before threading the sump on, lightly lubricate the EPDM o-rings with food-grade silicone grease. This prevents pinching during installation and makes cartridge changes much easier down the line, especially in commercial settings where frequent maintenance is critical.
