Valves control flow direction and isolate sections for maintenance in marine and RV plumbing. SEAFLO joker valves, check valves, and Y-valves support sanitation and bilge layouts.
Check Valves
Inline check valves prevent backflow when discharge lines rise above the waterline. Quick-disconnect models simplify service.
Joker Valves
Replacement joker valves restore seal in macerator and gravity toilet discharge lines — match your existing toilet brand pattern.
Y-Valves & Diverters
Y-valves select between holding tank and overboard discharge where regulations allow. Label positions clearly for crew.
Vented Loops
Vented loops break siphon action on elevated discharge runs. Required on many head installations to prevent flooding.
