I think it’s probably a great product just one was broken
I ordered 43 inch backwater preventers. The door has a tab that is broken on one of the backwater preventers. Should I send the part back or would you send me a new door/flapper?

What You Would Expect - Loose O-Ring on the Flap
This back flow preventer is exactly what you would expect. The only con that I have is that the O ring that is on the flap is not permanently installed - which can be a good thing, but it does not stay on the flap well. This can lead to it not sealing properly and not doing its job. Overall, I would recommend it, but I would just caution you to make sure that the o ring is seated properly and that it doesn't fall off during install or during the first couple of uses.

Stops toilet from overflowing
My downstairs bathroom toilet overflowed twice due to septic tank backing up. I installed this and now I never need to worry about the toilet overflowing, ruining my flooring. Very easy to install in you know how. Easy to maintain. Wish I did this years ago. Very good quality. Works perfect. Fits perfect. Silent operation does not restrict flow.
