Essential Info

The DIG Irrigation A201B applies fertilizer directly through your irrigation system, helping keep your garden green without extra hassle. The DIG filter/fertilizer applicator features a back-flow device to keep incoming water clean and prevent fertilizer from backing up into your home's plumbing. It will accommodate up to four spoonfuls of any water-soluble fertilizer at one time.

The only maintenance required is rinsing the screen with fresh water after each use to keep the filter/fertilizer applicator clean.

The DIG fertilizer accessory works perfectly. It includes a durable rubber seal. When threaded correctly, and tightened by hand, there is no leakage. I've used the same one for four years, adding Miracle-Gro once or twice a week to produce beautiful blooming baskets of flowers on our porch with minimal effort.

This item is junk. When it is hooked up it leaks like like crazy.
TRACY -- scranton, PA   7/5/2012
Fit great with my dipper system, easy to install. The only problem we have is it leaks a little, which will be fixed with some plumbers tape.

Outstanding quality. The first one I have seen with a leakproof backflow preventer. I bought three.
JAMES -- el centro, CA   9/3/2011
This is the first applicator I have used that doesn't leak through the backflow preventer. Easy to use, excellent quality throughout.
