It prevents backflow of water, clogs easily (but this design does that).
I wouldn't use this to keep sewage from backing up, but near the end of my gutters at the rain garden this works well to keep the deeper inlets from backfilling. Mount this in a place you can access it, it needs cleaned occasionally. As far as quality, some brands the plastic was noticeably worse than the adjacent pipe, these feel like a real fitting. The plastic is thick and overall the construction is solid. If you have sewage backing up somewhere research your situation. This probably isn't the solution. But taking into consideration what it does, it does that well.

Keeps animals and insects (mosquitos) out of the drain
Seems to be made of sturdy pvc, like schedule 40. I had several fittings on hand and was able to transition from cheap sewer pipe to this quite easily. Don't ask me how as I do not remember. I then attached a short piece of baling twine to the top and buried it to shield the fitting from UV rays. If there is ever a problem it should be easy to un-earth and clean it or whatever. It is very simple and completely take-apartable and fixable.

Excelente producto
El producto fue tal y como se describía, es de 6 pulgadas, el material es PVC y se ve bien robusto, es algo pesado, en total 10 libras. Lo recomiendo al 100%. Yo tuve que comprarlo en Amazon ya que en mi país (Nicaragua) no lo encontré por ninguna parte.

This valve looks better than expected
This valve looks better than expected. It's much thicker than 4" sewer or water PVC pipe. Looks to be built for, if not like, a brick Schitthause.This check valve is beautifully simple and designed to be, if required, easily maintained.Because the flapper can rise into an upper chamber, it can provide 100% unobstructed passage area thru the valve. Our city's recommended slope for waste water is 4 degrees, which translates to approximately a 1/4" slope, in to out, over the valves 10" length. The way it's designed, when it's installed properly, is that if the top of the valve is level - you have a proper slope. Nice!I'm planning to use this for storm water drainage so it will be located underground and outdoors. To mark the valve's clean-out, I plan to bury an upright pressure treated 2x4 beside the valve's clean-out, to about 6" below grade. This should facilitate for easier location once it's been covered.And on a final note: Thank you Google and Amazon for making the finding and shopping of this product so effortless.
