portable irrigation injector

[mcrawford]

This is a follow up to the thread from some months ago regarding injecting (acid, fertilizer, etc...) into the drip system.

Here is the old photo of the original wall mount.  I have included the portable version I have mounted on a dolly, trailing

an IN hose from the hose bib and an OUT hose to hand water.

Thanks for posting this, Monte. It seems straightforward, as far as fertigation goes. Does the wall-mount version lead off into an automatic timer or filtration system?u Or do you just hand- or hose-water? I want to combine your system into an overall manifold distributing two zones. Not sure where this would fit in.

Also, is there any backflow prevention on the system?

Code requires a backflow preventer.

There is a manual timer for the wall mount unit.  It goes

straight into the drip system.  One big advantage of injecting

acid beside lowering pH for improved fertilizer absorption is

the acidic water (pH 5.5) will keep the drip lines from plugging

up from salts.  Anyone w/a drip system knows of that headache.
