- Lubricate the O-rings on the new Watts Premier 105351 filter with clean water or food-grade silicone grease.

- Turn water supply back on, check for leaks, and flush the system for 5 minutes before use.
COMPATIBILITY
System Compatibility
This Watts Premier 105351 carbon pre-filter is designed exclusively for the Watts Premier RO-PURE and RO-4 reverse osmosis systems. It uses a proprietary 11-inch form factor and will not fit standard 10-inch housings or the Watts 1/4 Turn KWIK Change filter system. Confirm your system model before ordering to ensure proper fit.
🔧 Pro Tip: Replace the carbon pre-filter every six months even if water taste seems fine. Chlorine breakthrough damages RO membranes long before you notice flavor changes, and a $20 filter replacement is far cheaper than a $100 membrane.
