Certified Backflow Prevention
Testing & Repair in Bountiful, UT
Certified annual RPZ, DCVA, and PVB backflow assembly testing, relief valve rebuilds, and direct municipal compliance filing across Bountiful and South Davis County. Protect your potable drinking water from hazardous cross-contamination.
Utah State Certified
Cross-Connection Control
Bountiful City Water and Utah Division of Drinking Water mandate annual certified backflow testing on all irrigation sprinkler double-checks, fire sprinkler assemblies, and commercial RPZ valves.
Backflow occurs when pressure drops in municipal water mains, causing non-potable water, fertilizers, or chemicals to siphon backwards into your drinking water lines. Our state-certified testers use calibrated 5-valve digital gauge kits to verify check-valve differential pressures.

Backflow Prevention: Devices & Culinary Cross-Connection Control
Backflow prevention is the critical mechanical barrier shielding Bountiful's municipal drinking supply from non-potable contaminants. Learn how certified backflow assemblies isolate high-hazard culinary cross-connections per Utah state code.
Backflow Preventer Device Engineering
A backflow preventer device uses precisely calibrated spring-loaded check valves, differential relief mechanisms, and atmospheric ports to create an impenetrable one-way hydraulic barrier in your plumbing supply.
- check_circle Reduced Pressure Zone (RPZ / ASSE 1013): The gold standard for high-hazard containment. Features two independent spring check valves separated by a hydraulically driven differential relief valve that automatically dumps water if internal zone pressure drops within 2.0 PSI of supply pressure.
- check_circle Double Check Valve Assemblies (DCVA / ASSE 1015): In-line dual check containment engineered for low-hazard applications (such as dedicated fire sprinkler lines), preventing static, non-toxic water stagnation from reversing into culinary lines.
- check_circle Pressure Vacuum Breakers (PVB / ASSE 1020): Essential anti-siphon protection for residential lawn irrigation. Engineered with an internal air inlet poppet that snaps open at 1.0 PSI to break hydraulic vacuum.
- check_circle Hard Water Seat Rebuilding: Bountiful's 12–18 GPG mineral content precipitates calcium grit on check valve rubber discs. We stock OEM check springs and EPDM diaphragms to rebuild, lap, and re-certify failing devices on the spot.
Culinary Cross-Connection Defense
A culinary cross-connection is any actual or potential physical link between potable drinking water and an unapproved fluid source. Preventing cross-contamination is essential to protect public health across Bountiful.
- check_circle Back-Siphonage vs. Back-Pressure: Back-siphonage occurs when city main pressure drops (firefighting demand, line breaks), sucking contaminated fluids backward. Back-pressure occurs when downstream pumps, elevated storage tanks, or boilers overpower incoming city pressure.
- check_circle Secondary Irrigation Interties: In South Davis County, homes often have dual water sources (culinary drinking water and untreated canal irrigation). Code strictly forbids interconnecting these systems without approved air gaps or certified backflow isolation.
- check_circle Chemical & Commercial Isolation: Lawn fertilizer injectors, commercial hydronic boiler loops, dental chairs, and grease interceptors present severe chemical and biological backflow hazards requiring dedicated RPZ isolation.
- check_circle Utah DDW Rule R309-105-12 Compliance: The Utah Division of Drinking Water mandates annual certification of all containment assemblies. Our technicians perform 5-valve gauge testing and submit official paperwork directly to Bountiful City Water.
