I’ve seen a few that screw into the float sensor location. But maybe a DIY would be a good path!

Article please!

This book is sitting in our office. Is it actually a good read? Its very dusty so I always wrote it off as just another corporate book.

Wow I definitely need to check out that black one. What a great project idea too!
