A valve isn't necessarily the most glamorous piece of equipment we rely on for proper operation and failure preparedness - but important nonetheless. These valves work every time and provide just a little extra peace of mind that you don't come home to wet floors! Would recommend.

Affordable, and so far has worked flawlessly. Everyone should have one of these on your sump return pipe. Simple to install and its nice to be able to view the inside of it through the clear pvc.

Good value on a double union check valve. By Mr. Biggs on 12/16/09

Does what it was made to do prevent the back flow of water.
The unions make it handy for cleaning and replacement when it fails.
All check valves are subject to failure in the long run.
I would not depend on a check valve to prevent the draining of the main tank into your sump to prevent flooding. Design the sump to hold all the water that will drain from the main tank during pump or power failure.
This valve is a good value and I would recommend it to others when used in the right situation.
