Automatically drain your charged lines after it rains using our wet/dry valve and prevent problems with tannin leaching and anaerobic fermentation.

For ‘wet’ Rain Harvesting systems, it is important to drain your charged lines after it rains to remove any water remaining in the pipes. Draining this water prevents it from becoming stagnant and discoloured due to anaerobic fermentation and tannin leaching – and most importantly, stops it from being fed into your rainwater tank at the next rainfall event.
