Resin Blocking



The all natural resin blocking pipe additive

Just a few drops of RezBlock concentrate will keep your water pipe clean.  How is that 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, per or downstream.  Just add a few drops each time you change your water
