Wet/Dry Valve

Draining the water from your changed lines periodically will keep your water at it's best. Over time the water in your pipework can 'go off' due to anaerobic fermentation, which occurs in low oxygen environments (like pipes), especially when there are nutrients in the system (broken down organic matter). Discarding this water occasionally will ensure it doesn't reach your tank, so you only capture the best water.

Easily configured to be set up perfectly for your requirements in your system. You might want to drain the water frequently do you capture the very best... Or you might want to discard water less often if water is scarce... Either way, with the simple controls you can adjust the settings to suit your needs, even if they change over time.

Two AAA batteries. That's it. No wires. No hassles.
