Perfceto para tu drenaje. facil y economico

Producto exelente

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

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