i did a search on float switches and found a rather economical one for 35.00 bucks, hooked everything up and it works great.
no more dumping buckets in twice a day.

I have used few disigns of float switches in my tanks and found the most reliable and sensitive to a change in water level, simple mechanical float switch. Here's what i did:

BTW - Except for the aqua-clear suction cup. Where did you get the parts for it??
Thanks
The system is gravity driven. The float switch is a part of WC flush container
