Flush valve

On my travel supreme motorhome my black tank flush valve doesn’t let water past the valve.
Where can i get another or is it possible to clear this.
  • Yes, you access the nozzle and either replace or clean it out. Just 3 screws hold it on. It is NOT installed IN the tank. If you want to verify the check valve, hook up the flush water hose, go to the valve and slowly open each end. If water trickles out or slightly sprays water, the check valve is allowing water thru.

  • The check valve is probably fine. Your problem is the in tank nozzle is clogged. Doug
