Cal Spa Diverter Parts

Cal Spa diverter valve parts are used to repair or rebuild the diverter valves found in many Cal Spa hot tubs. These valves control the direction of water flow between different jet groups inside the spa.

Over time the internal components of a diverter valve can wear out due to heat, chemicals, and regular use. Replacement parts allow spa owners and technicians to repair the diverter valve without replacing the entire valve assembly.

Common replacement parts include:

  • Diverter valve stems

  • Internal diverter assemblies

  • Valve caps

  • Handles and knobs

  • O-rings and seals

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

Common Diverter Valve Problems

Customers often replace diverter valve parts when experiencing problems such as:

  • Cal Spa diverter valve leaking

  • Diverter knob hard to turn

  • Water leaking around spa diverter cap

  • Broken diverter handle

  • Jets not switching properly when turning the diverter
