Which Homes Need Annual Backflow Testing?
Michigan EGLE and local water authorities require annual testing of any backflow preventer connected to city water. If your home has any of these, you're likely on the list:
Lawn irrigation / sprinkler systems
In-ground or above-ground pools
Boilers and hydronic heating systems
Wells connected to city water
Fire sprinkler systems
Outdoor hose-bib and water features
By far the most common reason Grand Rapids homeowners need a test is a lawn sprinkler system — if you have one, expect an annual notice.

Residential Backflow Testing FAQs — Grand Rapids
If your home has a lawn irrigation or sprinkler system, an in-ground pool, a boiler, or a well connected to city water, your municipality requires an annual backflow test to protect the public drinking water supply. Grand Rapids, Wyoming, Kentwood, and most West Michigan cities mail these cross-connection notices each spring — and they set a deadline. We test, file the report, and get you compliant.
Yes. Lawn irrigation systems are the most common reason homeowners need annual backflow testing. Fertilizer, pesticides, and standing water around sprinkler heads can be siphoned back into your drinking water if the backflow preventer fails — which is exactly why cities require the yearly test.
Residential backflow testing is a flat $150 per device. If the device fails and needs repair or replacement, we quote that upfront — no surprise fees.
A single backflow device test takes about 15–30 minutes. We shut the water off briefly during the test, so your service is only interrupted for a few minutes.
Yes. We file your test report directly with the Grand Rapids water authority (or whichever city applies) — usually the same day. You get a copy for your records, and we keep a digital backup in case you ever need it.
Most failures are worn check-valve seals or springs that we can repair on the same visit with parts on the truck. If the device is cracked, frozen, or past its life, we'll quote a code-compliant replacement upfront and reschedule promptly so you stay compliant.
Spring, when you turn the irrigation system back on, is the ideal time — it lines up with most cities' testing deadlines and catches any winter freeze damage to the device before the season starts. We book up fast in spring, so schedule early.
Call us as soon as you can. Most cities send a warning before any water shutoff, but deadlines and penalties vary. We can usually test and file the same day to bring you back into compliance.
Yes. All NSP backflow testing is performed by ASSE 5110-certified technicians — the certification Michigan EGLE and local water authorities require for a test to count.
