hi all,
we have a lavac toilet with a henderson manual pump. we've had it for 15 years. aside from 2 diaphragm changes and period duckbill replacemnt it has performed flawlessly.
two week ago we experienced a "lockup". the handle would not move. under sustained pressure it gradually moved but after the up pull the same lockup. after a few repetions it returned to normal. chalk it up to freak accident. then a couple of days ago the same thing happened. today i blew out vent line with a hose but there was no resistance. i also ran a snake through the saltwater intake line again not clogged. the pump is pretty simple and i can't think of any circumstance which would cause the pump to behave like this.
any ideas welcome.
