Problem: The Groco HF head
has been backfilling with waste water
. I checked all valves and through all that process you can definitely hear water
being pumped into the blackwater tank.
I assumed it was the joker valve or simply something worn in the manual hand flush pump. So using the Groco HF Master Rebuild
Kit, rubber gloves, and alot of patience, I rebuilt it this afternoon.
Now it backfills slower than before but backfills nonetheless.
Has anyone had this problem? Any suggestion?
