Installing a drain catch box if fairly easy if you know what you are doing. Drain catch boxes help disperse water directed from down spouts. Drain catch boxes are also known as bubbler boxes because the water bubbles out the top of the box. After you mark your utilities, the first thing that you need to do is determine which way you want the water to run. Water should always flow away from your foundation. Depending on the grade of your project, it might be necessary to install your drain catch box over twenty or thirty feet away. In most instances, you should install your drain catch box at least five or ten feet away from your foundation. If you install your drain catch box too close, you will defeat the purpose of installing it. You need to make sure that you have enough drop from the down spout to the drain catch box. If you run your drain catch box up hill with out enough drop, your water may back up and not reach the box.
