Check Valves and Backflow Preventers
Available2,284 products
Check valves prevent backflow into sump disposal lines, wastewater lines, sewage lift stations, and ejector systems. Backflow preventers prevent contamination of potable water by keeping water from flowing backwards into a water supply line. Vacuum breakers keep water from siphoning back into the public drinking water system. Backwater valves protect against weather conditions that cause sewage overflow such as heavy rain. Foot valves are a type of check valve used in ponds and pools. Freeze relief valves prevent damage to plumbing systems if unexpected freezing temperatures occur.
