Bought an older house and had them scope the sewer before closing. Found roots in two joints. We used the video to negotiate the repair into the sale. Best money I spent on that purchase.

Backflow Testing & Repair in Dubuque, Iowa
Backflow prevention keeps irrigation water, boiler water and process water from being pulled back into the drinking supply when pressure drops. Most Dubuque 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 Dubuque 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 Dubuque homeowners about a battery backup, because an unbacked pump and a storm outage is how basements flood here.

Sewer camera before we finished the basement. Clean line, no work needed, and they said so. Plenty of places would have found something.

Straightforward people. Told me the repair on my eleven year old heater would work but probably only buy me a year, gave me both prices, and let me decide. No pressure either way.

Backflow Testing in Dubuque: common questions
How often does a backflow device need testing?
Annually in most Dubuque 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 Dubuque, 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.
Do you work on commercial properties in Dubuque?
Yes. Restaurants, salons, clinics, offices, churches and multi-tenant buildings across Dubuque. We schedule outside trading hours at no extra cost so a repair does not cost you a day of business.
