This injector eliminates the need for electricity and can operate in remote areas.

    Review by on Mar 25, 2015

    Pump works great. spliced it into my lawn irrigation system, I use it to fertilize my lawn. unit is very well built. Purchased this a year ago. and forgot to rate it. All my neighbors want it now, so had to come back to where I brought it. Best Price, Fast delivery. ( I know the liquid fertilizer makes the grass green, but couldn't do it without the delivery system Superdos 20.) One year in use and still going like new.
    Thank you QC

    great machine

    Review by on Sep 17, 2014

    This product works as expected. I connected it to my watering system for my orchid house. It runs on the house line at about 40 psi. There was no assembly required and was plumbed into the watering line in less than an hour including getting extra pieces of PVC from my dad's house. Changing the concentration is simple. It has only been in for a week now so I can't attest to its durability but it is made from heavy grade plastic that looks like it can last a decade. Highly recommend it so far for this application

    Review by on Jul 25, 2012

    They work great - we have ordered 4, and we are fixing to replace the other two we have here on the farm with 2 more Dosmatics! Love the adjustment feature on these medicators.

    Not a fan of the major assembly required, but nothing comes easy in life. Great product! Works without flaw.
