The Girard 2GWH-18 replacement pressure relief valve component is an OEM-style service part for Girard RV tankless water heater repairs. Use this page when the part you are replacing matches the small brass valve component shown in the product photo and your parts list calls for 2GWH-18 / SKU 2022107573.

Fitment check before ordering: 2GWH-18 is not the same part as Girard 2GWH-48 / SKU 2022107574. If your existing part is a larger brass relief-valve assembly with a lever, valve body, hex fitting, and discharge tube, compare it to 2GWH-48 instead of this listing.

When this is the right part

  • Your Girard tankless water heater parts diagram or service documentation calls out 2GWH-18.
  • The replacement needed is the small brass valve component shown, not the full external relief-valve assembly.
  • You are repairing a pressure-relief-related service point on a Girard RV tankless water heater and want the exact listed Girard/Lippert part number.

Important notes

  • Manufacturer/SKU reference: 2022107573.
  • Cross-reference part number: 2GWH-18.
  • For safe water-heater service, depressurize the system and follow the Girard service manual before replacing pressure-related components.

If you are unsure whether you need 2GWH-18 or the larger 2GWH-48 assembly, compare the shape of the removed part to the product photo first. The wrong style may not solve the leak or fit the same connection point.
