What makes it unique
Unlike generic shutoff valves, this Add-A-Line configuration is purpose-built to simplify adding a new water branch. The 5/8" inlet and 1/4" outlet are optimized for common fridge icemakers, water filters, humidifiers, and small-appliance feeds, turning what used to be a multi-step retrofit into a straightforward install. The brass body resists corrosion in fresh water lines, and the low-lead design prioritizes safety for family use.
Ideal use cases
- Feeding a fridge or ice maker with a dedicated 1/4" line from a domestic copper supply.
- Adding a water supply to a humidifier or whole-home water filtration system without major pipe rearrangement.
- Branching off a main line to serve a dishwasher, under-sink purifier, or other compact appliances.
Installation tips
For a reliable, leak-free connection, ensure you:
- Cut copper pipe square and deburr the edge for a clean seal.
- Use a new compression ferrule and tighten the nut by hand, then snug with a wrench—avoid overtightening to prevent leaks.
- Confirm the valve is fully open or closed with a quick test after installation, and inspect for any drips at the ferrule.
From retrofit projects to new installations, the Sioux Chief Add-A-Line 5/8 in Brass Compression Ball Valve helps you expand your water system with confidence. Its combination of durable brass construction, precise compression fitting, and a full-port, quarter-turn design delivers dependable performance where a new branch line is needed—now and for years to come.
