Solenoid & Servicing and ReplacementPreventing Sprinkler Activation –See the warning above regarding rotor activation when Solenoid is loosened or removed.There are three ways to prevent activation of the rotor when the Solenoid is removed from the Pilot Valve:• The best and most effective way is to shut down the main line or the sub-main line that supplies water to therotor that is being serviced. Be aware that residual pressure may reside in the system piping even after thatvalve has been closed. To purge residual pressure, activate a rotor or quick-coupler near to the rotor beingserviced or, move the selector to the manual On position.• A tubing clamp or locking forceps tool can be used to pinch the supply tube going into the Pilot Valve. Thepressurized supply tube runs from the inlet area of the rotor and up into the flange compartment then isdirectly connected to the bottom fitting on the Pilot Valve (fig 132). Caution – care needs to be taken and anappropriate tool used so as to not damage the tubing as it is clamped closed. A leaking supply tube will causethe rotor to weep water while deactivated.• A ¼” tubing retainer can be used to pinch the supply tube going into the Pilot Valve. Note that the tubingused within the TTS rotor’s flange compartment is 1 ⁄8” tubing, NOT ¼” tubing. To do so, bend the supplytubing together and slide the tube retainer over the bent end to hold the tubing closed. The pressurizedsupply tube runs from the inlet area of the rotor and up into the flange compartment then is directlyconnected to the bottom fitting on the Pilot Valve (fig 132). Caution – care needs to be taken so as to notdamage the tubing as it is bent closed. This procedure is not recommended in cold weather conditions. Aleaking supply tube will cause the rotor to weep water while deactivated.Fig 132Fig 13144
