New flapper fixed old valve!
my 13-year-old backwater valve flapper door tab broke. I purchased this unit and installed the new flapper in my old valve. worked perfectly. I had to trim the ends of the tabs and sand down the shoulders to square it up and make sure it's swung loosely. Once done I use the new gasket on the old cap. works great!

This is what you need!!
I installed the 2" valve on my basement slop sink a few months ago after my third sewage backup. Well yesterday all my neighbors were calling to see if I had as much sewage in my basement as they did. Not one single drop. This valve worked perfectly.

Worked out great for a drainage system install we did! Keeps the water from the downspouts from spilling into the drainage system under the yard as hoped!

Device worked well, I used it as a temporary check valve device on a suction hose to siphon water from a 4 acre pond to enable repair of a leaking earthen dam.
