Backwater Valves
Backwater Valves
(OP)
Anyone know if there is a backwater (check) valve that can be installed directly on the drain of a sink? I did a very quick search on the internet, and looks like most of the valves are designed for the main sewage line heading out of the building. I have a particular application where I only care about preventing backflow to a particular sink. Any advice appreciated.
I've cross posted this in piping engineering as well.

RE: Backwater Valves
What you might look at doing is indirectly connecting the sink drain to a floor drain. The floor drain would have to be located fairly close to the sink.
You bring the sink drain pipe to the floor drain and end it two pipe diameters above the opening. You can get funnel attachments for floor drain grates and locate the pipe inside the funnel, keeping the two pipe diameters distance from the floor drain grate.
Hope it helps.

The military can be horribly slow. He sent me a portion of the email chain that has been generated so far regarding his issue, and right now, there seems to be more interest in who is actually responsible for the situation rather than how can they fix it.
Unfortunately, when it comes to the military, there are substantial jurisdictional issues, so he can't just go to the local tenant's rights board and get action in that matter.

Hope he gets it resolved.
