## Discrepancy

DE-ICE PRESSURE CAUTION ILLUMINATED. RAN CHECKLIST AND THE RT OUTER BOOT SEEMS TO BE THE ONE WITH THE PROBLEM. LIGHT ILLUMINATES LATE OR NOT AT ALL. APPEARS TO INFLATE OK FROM OBSERVATION FROM THE FLIGHT DECK. MAINTENANCE REPLACED THE NR 4 DISTRIBUTOR VALVE ON THE RT SIDE. OPERATIONAL CHECKS GOOD. AIRCRAFT RETURNED TO SERVICE.
