      I'm on my second one of these and thought it best to share my recommendations. Firstly, the sump pump system I inherited did not have a check valve installed. So when it got rainy the sump pump would cycle constantly. Click, whoosh, click, whoosh, gurgle, click etc. Water would go up, water would come back down. I think every cycle it was lucky to get a cup full out the end of the pipe before the float fell turning off the pump and the water drained back out. Anyway, I installed one of these and it did the job perfectly for all of two days. I removed it to find that the plastic flapper had fallen through and was not flapping or sealing any more. For reference the height I was throwing water up was only 8 feet. I popped the flapper back through and noticed something very interesting. The flapper was off center. So over the short period of time I had it installed the water hammering back against it was enough to pop it through as it was not properly supported. I went back to my local Home Depot and took a look at the dozen they had left on the shelf. Of the dozen there was only one where the flapper was lined up properly. Needless to say I bought that one and I haven't had a failure yet. I can only assume this lack of alignment is a bored employee on the production line just throwing these through and there is no QC inspection. So, if you are heading out to buy one make sure you look through the entire box. You only have to look at a couple and you will see what I saw. I've also uploaded a picture of the bad one so you can see what to look for.
