I am replacing my sump pump including the check valve which is now leaking back into the crock. This one is clear, so you can see if it is leaking. Right now I am still searching for a replacement pump and mounting pipe. Once I get it installed I will update my review of the valve.It appears to be good quality with good clamps. Looking forward to see how it works and how long it lasts. My last one lasted 30 years and is still working so it has big shoes to fill.
