Question:
What water pressure range does the 55k btu water heater tankless Fogatti FG76FR need? I run off a 12V pump in my travel trailer.

Expert Reply:
Luis, the Fogatti # FG76FR runs water pressure of 14.5-116 PSI, with preferred pressure: 40-45 PSI, so it works great with a standard 12V RV pump usually around 40–60 PSI. Flow rate needs to be at least 1 gallon per minute to ignite. If your pump surges or is undersized, you might see temperature swings. The # FG66FR white version is identical inside.
Do you already have a pressure regulator on your city water inlet? That’s a good idea to protect the whole RV plumbing system. If you don't have one yet, I'd go with # CAM40064.
