Iowa water systems track backflow devices under state drinking water rules, and utilities in Iowa want a passing report each year from a registered tester.

Farm country brings its own cross-connections: livestock waterers, chemical mixing for crop spraying and well systems tied to rural water. Winters are hard on exposed brass, so most devices are drained or enclosed. Grizzly Backflow & Plumbing connects Iowa property owners with testers for annual backflow testing, cross-connection surveys and backflow preventer installation on new services. Call (833) 990-5874.

Why call us for backflow testing

Iowa Owners Call Us for Backflow Testing

Iowa farm properties often have cross-connections the owner never thought about: a hose in a livestock tank, a sprayer fill line on the yard hydrant. Grizzly Backflow & Plumbing connects Iowa owners with testers who spot those connections and recommend the right device.

Town properties get annual backflow testing on schedule with the report filed to the utility. Winter draining and enclosures keep devices from splitting. Call (833) 990-5874 for cross-connection surveys, installation and backflow prevention in Iowa.

Backflow testing FAQs

Questions about backflow testing

Common questions about backflow testing in Iowa.

Talk to a person

What happens if I miss the backflow test deadline?

Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.

What is the difference between an RPZ and a double check valve?

Both have two independent check valves. An RPZ adds a relief valve between the checks that discharges water to atmosphere if the checks leak, which is why it is required on high-hazard connections.

Will my water be off during the test?

Yes, briefly. The tester closes the shutoff valves on the assembly while reading the checks, so water downstream of the device is off until the test is done.

Does my lawn sprinkler system in Iowa need a backflow preventer?

Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.

Can a backflow preventer be repaired instead of replaced?

Often it can. Rebuild kits with new discs, springs and seals are sold for most brands. Replacement makes more sense when the body is cracked or parts are no longer made.
