Great product.
Great product. Worked as expected.

Perfect
Very easy to install. Works very well.

Takes a 5/8" hose!
Excellent product. Works beautifully BUT you will need a 5/8" hose to fit onto this barb. A 1/2" hose will not fit, even with softening the hose with a torch. I think the "1/2-inch Barb Connector" means the inside diameter of barb, not the size of hose that will fit on it. Very professional feel to the completed installation. Highly recommend. ... show more

has 1/2" barb for softener drain hose
It does work nicely and made the setup legal as far as code goes. One thing you have to be aware of is this particular piece has a 1/2" barb for the softener drain line. I think most softeners use the 3/8" line. No big deal, but I did have to get a piece of 1/2" hose and a coupler for the two size hoses. You can see in the image I'm posting. ... show more

Decent product
I bought two units, one for my house and the other for my parents house. Mine was great. Works as described. The one for my parents I cannot use. The drain hose from their water softener has a 3/8 hard plastic hose. I cannot find any fitting at the hardware store that will allow me to connect it to the air gap drain ... show more

Good product, easy to install
What I like about this kit, they really thought through, it should cover 99% of the conditions that you will normally face. No need to have a second trip to any local store in case you are missing anything.
