When the outlet pipe on your Girard GSWH-2 tankless water heater cracks, corrodes, or starts to weep, this OEM-spec replacement restores a clean, secure connection between the heater and your RV's hot water plumbing. The 2GWH-19A is designed for GSWH-2 heaters equipped with the matching 19A-style outlet pipe configuration.
Girard GSWH-2 water heaters may use different styles of this water pipe assembly. The 2GWH-19A is identified by the large hex-shaped nut on one end of the pipe and the downward-facing center connection. Please compare your existing assembly before ordering. If your pipe does not have the large hex-shaped end fitting, see 2GWH-19 instead.
The Girard GSWH-2 is a propane-fired on-demand tankless water heater built specifically for RV use. Because it runs on demand rather than holding a tank of water, every fitting in its plumbing circuit matters -- a weeping outlet pipe can lead to inconsistent pressure, water intrusion, and eventual corrosion. This outlet pipe (Girard part 2GWH-19A, Lippert part 2022107579) is designed to match the factory 19A-style outlet pipe configuration.
If your existing GSWH-2 outlet pipe has the large hex-shaped end fitting and downward-facing center connection shown on the 2GWH-19A, this is the matching replacement style. O-rings are not included -- order the appropriate GSWH-2 o-ring components separately if the originals are worn, flattened, or damaged.
6.5 inches in length and designed to match the factory 2GWH-19A outlet pipe geometry when used with the correct GSWH-2 configuration.
At 0.5 lbs, this pipe adds negligible weight and is sized for the compact plumbing bay found in RV water heater compartments.
Made in the USA to Girard/Lippert production standards for consistent fit and construction.
Designed to replace the matching 2GWH-19A pipe configuration without modifying the factory plumbing layout.
The GSWH-2 outlet pipe sits downstream of the heat exchanger and is repeatedly exposed to heated water, cooling cycles, system pressure, and road vibration. Over time -- especially after freeze damage or improper winterization -- the pipe or its sealing surfaces can develop problems. Symptoms may include:
Replacing the outlet pipe requires access to the GSWH-2 plumbing connections and should be performed by someone comfortable servicing RV water systems. General steps include:
