When your Girard GSWH-2 tankless water heater develops a leak or restricted flow at the outlet, this OEM-spec replacement pipe is the direct fix. The 2GWH-19 outlet pipe restores proper hot water delivery from the heater to your RV's plumbing system with the correct factory-style replacement.
Girard GSWH-2 water heaters may use different styles of this water pipe assembly. The 2GWH-19 does NOT have the large hex-shaped nut on the end of the pipe. Please compare your existing assembly before ordering. If your pipe has a large hex-shaped end fitting and a downward-facing center connection, see 2GWH-19A instead.
The Girard GSWH-2 is a popular on-demand propane tankless water heater found on a wide range of RVs. Like any component that handles constant thermal cycling and water pressure, the outlet pipe can develop cracks, corrosion, or fitting failures over time. A compromised outlet pipe leads to reduced water pressure, dripping, or outright water damage inside the heater bay.
Lippert's 2GWH-19 is the correct OEM replacement for this specific pipe configuration on the GSWH-2. At 6.5 inches long and weighing just 0.5 lbs., it installs with standard plumbing tools and fits into the factory location without modification when matched to the correct original pipe style.
Engineered to match the original 2GWH-19 GSWH-2 outlet pipe dimensions and connection points.
Precision-formed to seat correctly against the heater body and downstream plumbing, helping eliminate drips and seepage caused by worn or cracked originals.
A properly seated outlet pipe maintains full flow through the GSWH-2 system, helping restore the on-demand performance the heater was designed to deliver.
Manufactured to Girard/Lippert quality standards domestically, ensuring material consistency with the original factory part.
The GSWH-2 outlet pipe sits in one of the harshest positions in the heater -- it transitions heated water from the heat exchanger to the RV's hot water plumbing. This constant heating and cooling cycle stresses the pipe walls and fittings. Common failure modes include:
This is a straightforward replacement for anyone comfortable with basic RV plumbing work. Typical steps include shutting off the water pump and city water supply, depressurizing the system, draining residual water from the heater, removing the damaged outlet pipe, and installing the replacement 2GWH-19 assembly. Re-pressurize the system and inspect all connections for leaks before returning the heater to service.
