Why Backflow Prevention Matters
Backflow occurs when contaminated water – from irrigation, boilers, or industrial processes – flows backward into your clean drinking water supply. This can happen due to pressure changes, pipe bursts, or fire hydrant use.
Backflow prevention devices are required by most Texas cities for irrigation systems, commercial kitchens, medical facilities, and multi‑family properties. A properly installed and maintained device protects your family, employees, and customers from contaminated water.
Blue Otter Plumbing's licensed plumbers ensure your backflow prevention device works properly and meets all local codes. We make compliance easy – with repair, replacement, and installation services you can trust.
