Head still not cooperating

[Randy Jarrell]

Thanks for all the advice on my belligerent head. I too believed it to be a pressurized tank. I did as you suggested;reamed the holding tank vent, no luck. I then opened the main waste cap, no pressure in the tank (thankful for that)I then removed the vent line from the tank and reamed the tank vent. Head still very difficult to operate. Any more advice would certainly be appreciated. Thanks

Need a re-build?

Randy, has anyone suggested rebuilding the pump mechanism? It sounds as if something may be jammed or plugged in there. That happened once in my Groco HF. A kit may cost a few bucks, but if it has never been rebuilt, it may be time. It takes about an hour to do.
