Backflow Preventers

20 results found that include 203 products

Backfill preventers make sure that water doesn't flow backwards into a water supply line and contaminate the potable water supply. These tools make sure that even if something goes wrong in the pressure systems, your plumbing won't be contaminated with undesirable liquids and solids. Backflow preventers can be used in industrial settings where chemicals are connected to water lines and in municipal water systems.Close
