Protect Your Water Supply with Backflow Prevention

Backflow is a serious plumbing issue that can contaminate your drinking water with harmful substances. Whether it’s caused by a sudden drop in water pressure or a faulty connection, backflow can allow dirty water, chemicals, or waste to flow back into your clean water lines. That’s why municipalities require backflow prevention in many cases. Some instances include; homes with irrigation systems, sump pumps, or cross-connections to city water.
