Waste>>>TO DRAIN ---------- Feed---+----RO------ - - ---------- - Product>>>>TO 30 Gallon Trash Can_ - -----------Backpressure from Float Shuts of Solenoid I use a 50GPD Spectrapure RO system hooked to Kent Float Valve Kit, I drilled the side of the 30 Gallon trash can to hold the float valve, when full the float valve manually closes a solenoid to shut off the feed water, I then pump the water out with a little giant pond pump from the local hard ware store, put a ball valve in line on a PVC U at the end of the hose in order to be able to shut off the flow between tanks. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
