The All Natural Resin Blocking Water Pipe Additive
Just a few drops of RezBlock Conentrate will keep your water pipe clean. How is this possible? We use fruit and vegetable extracts that create a natural slippery coating that resin can't stick to. The resin stays in the water instead of sticking to your water pipe,perc and downstem. Just add a few drops each time you change your water.
