Used on a mostly clean water sump. Connected to 1 -1/4†sump outlet to 1 -1/4†drain outlet. IMPORTANT to note that you can flip the rubber connections around to adapt use on 1-1/4“ or 1-1/2†pipes simply by reversing the way they fit onto the square check valve section. There even was a slight lip to key the hose clamp on properly in correct alignment. I have done many well and sump check valves and honestly expect about a 3-5 year lifespan from these plastic types . It not that they are bad , its the way the check valve can normally get snotted up , or the plastic ages in the dirty water. Since they are cheap, expect to maybe replace some day. It took about 5 minutes to do mine.

It's a bit flimsy. I question the lifespan of this valve. However it did work. I put this on a sump and it did help slow the backflow from draining into the sump from the drain line which goes up hill for a long stretch before going back down.

Easy to install and gave size options. Perfect length, time will tell how long this preventer will continue to operate. They do have a lifespan.
Had to hold the wire into it for it to work

I like the quality. The last thing I want to worry about is my sump pump or discharge lines. I’ve had a cheap check valve come loose, but thankfully caught when it happened. I can sleep at night, now.
