What to do if the Flow Safe F8000 main valve leaks through the outlet?
- MMicheal GrimesAug 14, 2025
If the main valve on your Flow Safe Control Unit is leaking through the outlet, it could be due to: * Damage or contamination on the piston seat, main valve nozzle, piston seal/sealing surface, or lower liner seal/sealing surface. Disassemble the valve, remove the piston and liner, and examine the seat, seals, and sealing surfaces under magnification. Replace damaged parts or clean contaminated parts before reinstalling. * The dome is not loading properly through the pilot. See “The main valve does not close” for troubleshooting steps.
