Culligan SY-5197 Water Filtration System
If you need to replace the housing sump, the Pentek 153017 sump is the replacement sump. It is blue in color but fits the same. Use the OR-38 o-ring for the SY-5197 system. The Culligan Ametek SY-5197 has been discontinued but the replacement water filters are still available. The first SY-5197 housing uses the CC-10 water filter. The second SY-5197 housing uses the CBR2-10R water filter. If you need to replace the system, use the Pentek US-1500 water filtration system.
