Product Details

The Atwood Mobile 90029 is the OEM replacement mixing valve designed specifically for Atwood XT Series RV water heaters. This thermostatically-controlled valve blends ambient temperature cold water with hot water from the heater tank to deliver consistent, safe hot water output throughout your RV.

The Atwood XT water heater system uses Exothermal Technology to provide the hot water capacity of a 16-gallon unit from a compact 10-gallon tank — and the 90029 mixing valve is a key component in making that system function correctly. Over time, mineral buildup and hard water deposits can clog or restrict the original valve, reducing hot water flow. Replacing it with this OEM part restores full performance.

Key Features:

  • Thermostatically-controlled mixing valve combines cold and hot water for consistent output temperature
  • Designed as an OEM direct replacement for Atwood XT Series water heaters
  • Compatible with 10-gallon XT models including G16EXT, GE16EXT, and GEH16EXT
  • Features check valves in both inlets to prevent backflow
  • Valve-only replacement — does not include hoses or tee fittings
  • UPC: 765053837613

Also sold under the Dometic brand as part number 90029 following Dometic's acquisition of Atwood Mobile Products. This is a direct OEM-equivalent replacement for RV owners experiencing reduced hot water pressure or inconsistent hot water delivery from their XT series water heater.
