Thanks madmapler. Their is another pump that with the unit. I don't know if this set-up will work or not? I have time to get it all figured out before maple season. The unit came from a water supplier that bottled water to sell in stores that had financial problems and closed down 8 months ago. I put pictures on the other site but can't figure out how to put them on this one yet? I don't think it is home made but don't see a make on it yet. All the parts I looked up on line seem like good quality stuff, motors, flow valve, membranes, valves and the plumping looks professional. It would be a shame to just throw it all away so I am going to try and make something to fit my needs. Their is so many parts that it will take time to figure it all out? .....Thanks again Vernon
