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. At 6.5 inches long and just 0.5 lbs, it drops in with standard plumbing tools and gets your hot water back online without a service-center visit.
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 means inconsistent pressure, potential water intrusion into the burner cavity, and eventual corrosion. This outlet pipe (Girard part 2GWH-19A, Lippert part 2022107579) is manufactured to the same dimensions and material spec as the original, so fit and flow are correct right out of the box.
This is a direct replacement part. If you're seeing a drip at the hot-water outlet port of the GSWH-2, or if you're doing a proactive rebuild of the water circuit after winterization damage, this is the pipe to order. O-rings are not included -- pick up the correct GSWH-2 o-ring kit separately if yours are flattened or cracked.
6.5 inches in length, matched to the factory outlet port geometry of the GSWH-2 for a no-modification install.
At 0.5 lbs, this pipe adds negligible weight and is sized to clear the tight plumbing bay typical of RV water heater compartments.
Made in the USA to Girard's original production standards, ensuring consistent wall thickness and thread integrity.
No specialty tools required. A basin wrench or channel-lock pliers and thread-seal tape are typically all you need for the swap.
The GSWH-2 outlet pipe sits downstream of the heat exchanger and sees the hottest water the unit produces. Over time -- especially after repeated freeze-thaw cycles or improper winterization -- the pipe can develop hairline cracks, corroded threads, or deformed sealing surfaces. Symptoms include:
Installing this outlet pipe is a straightforward task for any DIY-capable RV owner comfortable with basic plumbing. General steps:
