They replaced our old tank with a tankless unit and actually upsized the gas line to do it properly. The previous quote we had did not mention the gas line at all, which I now understand would have been a problem.

Backflow Testing & Repair in Shenandoah, Iowa
Backflow prevention keeps irrigation water, boiler water and process water from being pulled back into the drinking supply when pressure drops. Most Shenandoah water authorities want an annual test on any device protecting a commercial building, a fire line or a lawn irrigation system.
Call (833) 435-9778 and describe what is happening. We will give you an arrival window before you hang up and a flat price before anyone starts work - the same price at 2am as at 2pm.

Spring thaw is when sump pumps get tested
A sump pump in Shenandoah sits idle for months and then has one important night. That is usually also the night the power flickers. We check the float, the check valve and the discharge line, and we talk to most Shenandoah homeowners about a battery backup, because an unbacked pump and a storm outage is how basements flood here.

Sump pump died during a storm. Called at 11pm, got a person, had a new pump and a battery backup in the next morning. Basement stayed dry through the rest of the week.

We run a small restaurant and the grease line backed up during service. They jetted it after we closed that night so we opened normally the next morning. That flexibility is worth a lot to us.

Backflow Testing in Shenandoah: common questions
How often does a backflow device need testing?
Annually in most Shenandoah jurisdictions, and some commercial and fire applications more often. We keep your date on file and remind you before it lapses.
What happens if my device fails the test?
We rebuild it and retest. We carry kits for the assemblies we see most in Shenandoah, so failures are usually resolved on the same visit rather than turning into a second appointment.
Do you file the paperwork with the water authority?
Yes. The completed report goes to the authority and a copy goes to you, so there is nothing left on your desk to chase.
Should I have my irrigation backflow tested before winter?
Test on your normal annual schedule, but do winterise the device before the first hard Iowa freeze. A cracked assembly from freezing is a far bigger bill than a test.
Can you come out the same day in Shenandoah?
Yes, most Shenandoah calls are handled the same day, and genuine emergencies - flooding, sewage backups, no water, gas smells - get moved to the front of the queue immediately.
