Question:
Will the Fogatti FG38FR work with my onboard water pump, or is it only for city water?
asked by: Chris
Expert Reply:
Chris, the Fogatti Tankless Water Heater w/ black door # FG38FR works with either. Your onboard pump typically 40–55 PSI, ~3–4 GPM provides enough pressure and flow to fire the heater. On city water, you’ll want a regulator around 45 PSI to protect your RV plumbing. The # FG58FR is identical, but has a white service door if that matches your RV better than black.
Do you camp mostly at campgrounds with hookups, or are you running the pump off-grid more often?
