    Do not let the plastic scare you!
  

*by J***I on Reviewed in the United States on October 13, 2023*

If you live in an area where metal theft is common this is the way to go. Or in my case you are looking to save you or a customer money on RPZ. The RPZ was high quality and meets all lead codes for potable water. Repair parts are available from the manufacturer and is easy to do as well.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars
