PiloT VAlVe RePlACeMenT
See the warning above regarding rotor activation when Solenoid is loosened or Pilot Valve tubing is disconnected.
there are no serviceable parts within the tts rotor’s pilot Valve assembly. If the filter inside the pilot Valve becomes
obstructed, the water flow through the Pilot Valve can be reduced. A substantial reduction in water flow through the
pilot Valve will prevent the rotor’s Inlet Valve from opening fully.
notice the two tubes attached to the pilot Valve’s fittings (fig 136). the lower fitting is the inlet and the upper fitting
is the outlet. the lower tube is the pressurized supply tube that comes from the rotor’s Inlet Valve at the bottom of
the rotor. the upper tube goes from the pilot Valve to the inlet of the pressure regulator. to replace the pilot Valve,
use side-cutters or blade to make clean cuts at points just before the fittings on the pilot Valve. trim & remove the
remaining tube from fittings.
