Marquis Spa Diverter Parts

Marquis Spa diverter valve parts are used to repair or rebuild diverter valves found in many Marquis hot tubs. These valves allow spa users to redirect water flow between jet groups inside the spa.

Over time the internal diverter valve components may wear out due to heat, chemical exposure, and regular operation. Replacement parts allow the diverter valve to be repaired without replacing the entire valve assembly.

Common replacement parts include:

  • Diverter valve stems

  • Internal diverter assemblies

  • Diverter caps

  • Handles and knobs

  • O-rings and seals

Replacing worn components can restore smooth diverter operation and eliminate leaks around the valve handle.

Common Diverter Valve Problems

Spa owners often search for replacement parts when experiencing:

  • Marquis diverter valve leaking

  • Water leaking around diverter knob

  • Diverter knob hard to turn

  • Broken spa diverter handle

  • Jets not switching properly
