Does anyone have a way to make an inexpensive moisture trap? Never had one installed when we purchased the system as they never even mentioned it. Now we are dealing with stuck vanes cause sap got into the pump. And on that note, does anyone have any different ways to get the vanes unstuck without taking apart the pump? We have put kerosene in, and even put warm kerosene in hoping that the heat would disolve the sugar, but no luck so far.
