Are there any diagrams that show how it should be configured? I've searched but to no avail.Adding additional fresh water tank: no pressure to faucetsHello, This is my first post and I'm pretty green to plumbing and diy in general. I am trying to plumb in an additional fw tank. I have it mounted underneath, along side my original tank with a pex fitting t'd into the original tank's pex line. The problem is now that the pump only seems to be pumping water into the tanks, and not the other way, up into the unit and to the sinks. There is no pressure in the sink when turning on the spigot. I'm sure I'm missing something. can anyone lead me in the right direction? http://postimg.org/image/5grld1hmj/
