Secondary input screen
The input on the top from the top. There are 2 screens in there. One is a coarse screen and the other in the center is a fine screen. They are both available at most hardware stores. The small screen in the center is between two washers. You will need to make this one. Witout a screen the baffle pipes will plug up in a very short time. It is much easier to clean out the screens than the baffle pipes.
