How often does a backflow preventer need to be inspected?

Inspection frequency depends on local rules and your plumbing setup. A Sierra plumber can confirm the right schedule during our free backflow testing service and provide a written report with recommendations for your Las Vegas home. Our S.A.M. plan includes a 65-point plumbing inspection with a backflow check, up to four visits per year for $16/month. Same-day service is available if booked by 6 PM. No service-call or dispatch fees.
