NewPig Drain Blocker

Unfortunately in the C-store industry the drain blocker is a necessary must have item. While Pigs products in this category are a slightly higher cost than other comparable products, they definitely retain the highest bang for your buck ratio. I've only had to use the pig drain blocker on one occasion, but it lived up to its reputation. The product quickly adhered to the surrounding area so that no product could enter the storm water drain. The high vis yellow works well to deter customers in the initial moments when a barrier has not yet been deployed. Additionally for the money spent it seems as though the longevity of this re-useable product will far outweigh the cost. The product was delivered quickly and down the road when these products do need to be replaced I would see no reason not to replace with more Pig Drain blockers. With proper use and maintenace I won't need to replace these products anytime soon as they are re-useable unlike competitors cheaper solutions.
