EZ Flo isn't pumping out fertilizer
I've been disappointed in the results of our professionally installed system. Plants just don't seem robust. After a year with the contractor, we decided to do it ourselves. when it came time to refill the tank, we found to our surprise that it looked full of fertilizer ... nonetheless, we added more according to the directions after emptying half the tank ... the system pumps out water not fertilizer ... everything seems to be functioning but it's not sucking up the fertilizer ... probably what's been going on all along. We have an EZ Flo 1.5 gallon unit ... any thoughts are greatly appreciated.
