| Description: | This page shows the concepts of how an Overflow/Syphon box for a Wet/Dry filter works. It also gives you an idea of how mine is built. Note that I did not build my own because I had an old one on-hand. But it's basic acrylic construction. You need to be very precise on the outside box if you are building your own, because if that part leaks, your floor gets all wet! |
