Has anyone had to replace the main discharge hose from the head to the holding tank. The plunger on the Head builds up pressure when pumped. I have checked the all vent hose blockages, replaced the Joker valve, put a "snake" into the head end, but it only goes about 3 ft and then is blocked, but does not have any material on it when extracted. I assume there is an anti siphon loop somewhere
Thanks in advance
