At The Water Market one of the services we provide is Tannin Removal. But what is Tannin? Tannins are organic compounds that are the byproducts of decaying vegetation in the ground. They are essentially tea, and discolour your water, similar to the wine discolouration in the photo here. Tannins can cause staining to white fabrics and fixtures. Learn more at www.WaterMarket.ca
