DIY Electric shut-off valve

I needed a automatic shut-off valve for my RO-DI system and it had to be before the water line got to the RO-DI unit. So I decided to see what I could come up with. I went to Wal-Mart and got a Automatic Float Switch ($11.28) in the boating section. Then I went to Lowe's and got a 1'' Sprinkler Valve ($10.92) and a 24V Transformer ($12.97) in the sprinkler section. I already had the pvc pipe fittings (~$6).

This is how I hooked up the pvc fittings to the Sprinkler Vlave.

Here is how I set it up. If you can't tell how I hooked it up or have a question, just ask

A picture of the holding tank (trash can) with the Float Switch and final water line from the RO-DI unit. To mount the Float Switch I just cut out a peice from a plastic 'shoe box' and bolted it to the trash can with stainless steel hardware. Where it bolted to the trash can I used rubber washers to keep it from leaking.

Full shot of my set up.
