This is what I am going to use on my water change system.

These are easy to come by for me since I work in the HVAC field and they are regular truck stock. It will be wired in with a sprinkler valve (24vac)to shut it off when the tank is full and turn it on when the tank is low on water.
If your are interested in one let me know. I can find out what my cost is from work and send one to you for cost plus shipping.
