Great replacement!
Our landscaper manage to damage our other one that was installed at the time the house was built, and we decided to replace it with this particular one. It was easy to set up and install. No problems whatsoever. Nice quality and well-made.

Perfect fit
Fit perfect for connecting my backwash pool pvc to a pop up valve so I can flush away from the house foundation. The valve didn’t close down after the flush but it isn’t a problem to just close it back manually.

Steel clamp missing in 1.5 inch side
It worked because we had an extra clamp laying around, but this arrived without a clamp on the 1.5 Inch side.It fit my 3 inch underground PVC discharge pipe and the 1.5 inch PVC pipe from the sump pump. So far seems to have fixed the chronic leak from the previous PVC only connection.
