Why Does My Device Need To Be Tested Every Year?

If you are searching “Why does my device need to be tested every year?” you are not alone. Many property owners and facility managers use the word “device” when they mean a testable backflow unit. For clarity, we refer to the testable unit as a backflow prevention assembly. Let’s explain why Backflow Testing is important, what can fail over time, and how testing schedules work in Michigan.

Backflow prevention assemblies include internal components, including rubber parts, that can deteriorate over time. Valves can fail, often around once every five years. Because failures can happen without warning and backflow can create serious health and safety hazards, many authorities require Backflow Testing on a set schedule and require documentation for compliance.

What wears out over time

Backflow prevention assemblies contain moving parts and seals. Rubber components may be damaged or deteriorate over time. Even if everything seems fine day to day, wear can affect performance. That is why regular Backflow Testing is an important safeguard.

Why testing protects more than compliance

Backflow can introduce non-potable substances into drinking water through a cross-connection. That creates real health and safety risks. Testing helps verify the assembly is functioning within specification so it can do its job when pressure conditions change.

Is testing always yearly in Michigan?

Testing schedules can vary by city. Some cities require annual testing, while others may allow testing every three or five years. Residential schedules can vary by application, such as every three years on irrigation and yearly on isolation assemblies.

If you are unsure what applies to your property, a team that works closely with authorities can help confirm the correct schedule.

What a Backflow Testing visit includes

FAQs

Why is Backflow Testing required at all?
Because backflow can cause serious health and safety hazards, and assemblies can wear out or fail over time.

Is “device” the same as an “assembly”?
People often search “device,” but a testable unit is more accurately called a backflow prevention assembly in customer-facing explanations.

How often do valves fail?
Valves can fail about once every five years. Testing helps catch issues before the assembly stops protecting potable water.

Is testing always annual everywhere in Michigan?
No. Some cities require yearly testing, while others can be three or even five years. Residential schedules can also vary by application.

If my assembly fails, can you repair it?
Yes. Repairs are completed by ASSE 5110 and 5130 certified, licensed plumbers after you approve a written quote.

Do you submit certificates to the city?
Yes. Certification documentation can be submitted to the appropriate authorities on your behalf.

“Why does my device need to be tested every year?” It comes down to wear, risk, and verification.
