    Drain Cover does the Job!

    "We keep these covers in our stock in case of a chemical spill. We did have a smaller spill outsdie that required a cover over one of the drains. The drain cover held the water back from going down the drain as we washed up the area. Basically no chemical would have gone down the drain due to the socks and mats we use from New Pig, BUT the cover was an extra measure to protect our city water and creeks. It is the right thing to do!"
