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 -- no fabrication, no adapters, no guesswork.
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 location on the GSWH-2. At 6.5 inches long and weighing just 0.5 lbs., it installs with standard plumbing tools and drops directly into the factory position without modification.
Engineered to match the original GSWH-2 outlet pipe dimensions and connection points -- no trimming, drilling, or adapter fittings required.
Precision-formed to seat correctly against the heater body and downstream plumbing, eliminating the drips and seepage that worn or cracked originals develop.
A properly seated outlet pipe maintains full flow through the GSWH-2 system, so you get 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 superheated water from the heat exchanger to the RV's cold supply lines. This constant hot-to-cold cycling stresses pipe walls and fittings. Common failure modes include:
This is a straightforward swap 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 threading or pressing the 2GWH-19 into place. Reinstall, re-pressurize, and check for leaks before relighting the heater.
