| What you can do is to obtain a solenoid valve for use in regular plumbing. You can set this valve up so that it controls the input to your RO/DI unit. Set up your RO/DI unit so the output goes to your sump or kalk reactor. Then use a float switch in your sump to control the solenoid valve on the RO/DI unit.
When plumbed this way, you don't need a bucket anyplace at all, and the output from the RO/DI is about the speed you want to add water lost to evaporation. |
