The all-natural resin preventer for water pipes.
Add a few drops to your water
Prevents resin build-up
Safe for the environment
A few drops of RezBlock in your pipe will stop resin from sticking to the pipe anywhere water touches. Special fruit and vegetable extracts in RezBlock create a naturally slippery coating that resin CAN’T stick to. Instead of sticking to your water pipe, downstream, and perc, resin just pours out when you change the water!
