Chevrolet Suburban 161109 Gas Valve for SW-Series Water Heaters — 3/8" NPT Inlet, 1/4" Outlet Compact Replacement

This 161109 gas valve fits SW-series Suburban water heaters and replaces the factory gas control in many recreational vehicle and marine hot-water systems. It’s designed for straightforward plumbing and gas line connections, and its compact footprint makes it suitable where space is limited. While appearance can vary slightly from images, the specifications and port sizes — 3/8" NPT inlet and 1/4" outlet — are consistent with SW-series Suburban MFG valves.

What does this gas valve do and why would I replace mine?

The valve regulates the gas flow to your Suburban water heater burner and acts as the interface for the heater’s gas supply. Replacing a worn or leaking valve restores safe, reliable ignition and consistent burner performance. Typical reasons to replace include persistent leaks, inability to light, or incompatibility after other component swaps.

• Directly controls propane or natural gas flow to the burner
• Matches SW-series Suburban mounting and port layout
• Restores proper ignition and prevents gas leaks when defective

How do I install the 161109 valve in my water heater safely?

Installation should follow manufacturer instructions and local gas codes; if unsure, hire a licensed technician. Turn off the gas supply, disconnect the appliance, and verify fittings match 3/8" NPT inlet and 1/4" outlet threads. After fitting, test all joints with a safe leak-detection solution and follow the heater’s lighting and safety checks.

• Shut off gas supply and power before starting
• Confirm thread sizes: 3/8" NPT inlet, 1/4" outlet
• Use proper sealant for gas fittings and pressure-test connections

Will this gas valve fit my Suburban water heater model?

The 161109 is specified for SW-series Suburban MFG heaters; compatibility depends on your heater’s model and the valve mounting pattern. Check your original valve part number and the inlet/outlet thread sizes to ensure a match. If the original valve differs in shape or port orientation, compare dimensions and mounting points before purchase.

• Designed for SW-series Suburban MFG water heaters
• Verify part number and port sizes against your existing valve
• Physical fit and mounting orientation should be checked prior to installation
