Hi Bob,
Great info. sounds like we are on the same path... maybe we can get a combined discount if we both go a similar route.
I HAVE talked to the Smith people, and they are equally helpful. These things will probably outlive a "Twinkie" LOL....
The two deal breakers for me at least are:
1. The fact that that it doesn't seem possible to have a unit that will work with both low flow and high flow because the unit works as a hydro-motor of sorts, and takes a certain amount of pressure and flow to get the pump going... If you want one unit that will work with a single hose AND a wide open 1 1/2" pipe (to do rows of benches or spitter/drippers) you can't do it without having two different pumps. (they are very expensive units)
2. You are absolutely limited to the engineered mix ratio of the pump as delivered, so can not change anything but your dilution ratio to make delivery adjustments. They do offer a two head pump that can be used for delivery of two different solutions... or doubling up to double the delivery ratio.. but that is it.
If you have a "Set and Forget" type requirement, I think you couldn't find a better piece of equipment... but for varied needs and flows, or computer control, the Anderson would be the answer for sure.....
