Built and ran a nice 4 x 40 XLE this year and have nothing but great things to say about it except it takes a lot of permeate to keep it going. I was thinking of adding a 2.5 x 21 XLE membrane next year to the unit. I could run them in parallel and have the option to turn off one or the other depending on how much sap I collected. I ran into the problem of not having enough sap because half of my taps were froze solid for three weeks while my other taps were running well. The 2.5 x 21 would need far less permeate to wash the unit. Any thoughts?
