Tondiamo 4 Inch Backwater Valve Drain Backflow Preventer Valve Prevent Sewage and Rainwater from Flowing Back(White PVC)

This pipe works perfectly. It lets the water out and keeps the "critters" from crawling back into my basement.

Me esta funcionando muy bien

Got it last year I installed it sometime around four of last year 24 so far it’s doing its job. I live on the bottom of the hill and the water comes up over the sewer and I had that drain in my backyard that taps into the sewer and it acts like a overflow and I don’t have that problem no more very happy
