Buying Guide
What should you check before buying a replacement pilot assembly?
- Model compatibility: Verify your water heater’s brand and GS/GSX, or RLP/REM series, to choose a matching pilot assembly.
- Included components: Some kits include thermocouples and ignitors; others are just the pilot assembly. Decide based on whether you need a full kit or a partial replacement.
- Gas type: Confirm whether your system uses natural gas or LP propane and select a kit that supports that gas type.
- Installation requirements: Some parts require turning off gas and basic hand tools. Ensure you’re comfortable with DIY installation or plan professional help.
- Quality vs. OEM compatibility: Non-OEM parts can save money but may have different tolerances. Look for solid materials and secure mounting options.
How to install a pilot assembly safely?
- Turn off the gas supply and electricity to the unit if applicable.
- Remove the burner door and old pilot components carefully.
- Install the new pilot assembly following the manufacturer’s instructions, avoiding bending the pilot tube excessively.
- Check for gas leaks with soapy water after installation.
When is replacement preferable to repair?
- Repeated ignition failures or intermittent heating persist after a single-part repair.
- The existing pilot assembly or thermocouple shows visible damage or wear.
- Cost or availability of OEM parts makes full replacement more economical over time.
Common considerations by buyer type
- DIY homeowners: Prefer all-in-one kits with clear instructions and essential safety components.
- Service professionals: Look for compatibility breadth and robust materials to accommodate multiple brands.
- Renters: Choose cost-effective, straightforward replacements with simple mounting and minimal tools required.
