Why selected: It consolidates valve, thermostat, and regulator, reducing compatibility concerns. Limitation: Verify model compatibility before purchase to ensure fit with your exact heater family.
Reliance Water Heater Natural Gas Control Valve 100112336
The Reliance 100112336 control valve is designed to work with A.O. Smith, Reliance, State, and American-branded water heaters. This model emphasizes professional installation, as noted in its description, due to potential warranty implications when installed by a non-professional. Best for professional technicians replacing generic gas valves across multiple brands. Limitation: Homeowners should seek professional installation to avoid warranty issues and ensure proper safety compliance.
Bradford White Icon 2.0 2″ Gas Valve Kit (415-52907-02)
The Bradford White Icon 2.0 kit is a universal replacement option for Icon-era systems with a 2″ gas line. It features millivolt-powered control requiring no external electricity, a pilot-on indication, and simple 1-2-3 lighting instructions. Best for Bradford White installations or anyone upgrading from older ICON valves where electrical independence is valued. Limitation: Ensure your system uses the Icon 2.0/2.0 family and check compatibility with your current pilot setup.
Bradford White Icon 1″ Gas Valve Kit (415-52907-01)
This 1″ Icon valve kit mirrors the 2.0 version but is sized for systems using a smaller gas line. It maintains a millivolt-powered control and a simple setup with a 1-2-3 lighting sequence. Best for Bradford White appliances or older ICON valves that require a 1″ gas line. Limitation: Confirm exact valve size in your unit to avoid misfit and ensure proper seal integrity.
110-326 Chuuparts Gas Water Heater Control Valve
The 110-326 Chuuparts valve is designed for tank-type natural gas water heaters and includes built-in ECO (Energy Cut-Off). It regulates gas flow and controls temperature with a built-in safety feature that automatically shuts gas flow if the water overheats (160°F). Best for safety-conscious replacements where ECO is a priority. Limitation: Double-check the valve’s inlet/outlet sizes and pressure requirements to ensure compatibility with your heater’s specifications.
UCELICE 161109 RV Gas Valve
The UCELICE 161109 valve is aimed at Suburban RV water heaters and similar SW series configurations. It is designed as an electrically operated valve controlled by the water heater’s circuit board, with 3/8 inch inlet and 1/4 inch outlet connections. Best for RV setups or compact residential applications where space and specific RV compatibility matter. Limitation: Not ideal for standard residential water heaters unless the system matches Suburban RV valve requirements.
Buying Guide: Key Purchase Considerations
- Compatibility: Match valve type (1″ or 2″ line, millivolt vs. electrically controlled) to your water heater model and gas line size. OEM-style replacements often minimize fit issues.
- Control System: Consider whether a millivolt-powered valve (no external electricity) or an electronically controlled valve better suits your installation and safety requirements.
- Safety Features: Built-in ECO or overheat protection adds a layer of protection for your heater and home.
- Installation Requirements: Some valves require professional installation to preserve warranties and ensure gas and ignition safety. Review manufacturer recommendations.
- Brand Compatibility: If you own a branded system (Rheem, Bradford White, Bradford White Icon era, etc.), using a compatible valve kit can simplify maintenance and reduce the risk of misfit parts.
- Warranty and Support: Check whether the valve is designed to be a direct replacement and whether professional installation is recommended or required by the manufacturer.

- Can I replace a valve with a universal kit?
Yes, if the kit matches the heater’s model, gas line size, and control type. Verify compatibility before purchase.
- What safety features should I look for in a new valve?
Look for built-in ECO (energy cut-off) and clear indicators or pilot indications where applicable.
