Softener Airgap

[Indybipe]

Our softener is in our basement with all drain lines overhead. so I want to run it up about six feet to a bath room sink drain just overhead and replace the sink down pipe with one that has a 3/4 inch side pipe ,( one that is used for a dishwasher drain attachment ). Side pipe angles up some.
Can I use the sink type Airgap to hook my Softener drain to it?
Or will there be too much flow for it to handle to drain with out shooting water every where?
My Softener drain spec shows 1.6 gpm max.

Side note, there is a floor drain in the cement floor, though only the furnice A/C drain pipe goes to it and I don't trust the builder put anything more than a pit below it.
We are on city sewer and the house waste line for the entire house drops down from the floor joists and turns to exit the cement wall about 4 feet above cement floor. Thank you.

That should not be a problem.

Check the size of the bathroom tailpiece compared to tailpieces equipped with a dishwasher drain connection. A bathroom sink drain tailpiece will often be 1.25" diameter whereas a kitchen sink drain tailpiece is usually 1.5" diameter. If the correct diameter tailpiece with a side connection is not available to fit your bathroom sink drain, you may need to add a standpipe behind the bathroom vanity for the softener to discharge into.

1-1/4 branch tailpieces are rare but exist.
You could perhaps use 1-1/2 drain stuff with a reducing slip joint washer.

But if you did need the 1-1/4 branch tailpiece, you could maybe find one of these: http://www.gotomahawk.com/products/...lties/brass-tubular/lavatory-branch-tailpiece

Thank you we will check pipe sizes.

In my experience, wash basin drain assemblies are 1.25" and so it is not only the slipjoint connection that is a potential issue, but also the upper connection near the basin.

Great that 1.25" branch tailpieces are available, even if uncommon.
