I have one. This came out of my now shut down BC29. The float bracket slips over the wall between 2&3 chambers. Floats go into chamber 2. It is a Autotopoff.com low voltage system. This saves your float switches from havIng high voltage going through them eliminating float switch burnout. I will sale the whole system with the Aqua lifter pump. All you will need is a container to hold your TO water. $55 shipping included. PayPal accepted. PM if you are interested.
