They handled the permit for our water heater replacement so I did not have to think about it. Inspection passed first time.

Backflow Testing & Repair in Rock Valley, Iowa
Backflow prevention keeps irrigation water, boiler water and process water from being pulled back into the drinking supply when pressure drops. Most Rock Valley 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.

Tree roots and the front yard
Mature trees are one of the nicer things about older Rock Valley streets and one of the harder things on sewer lines. Roots do not break into a sound pipe - they find a joint that has already opened slightly and then widen it. Cutting them buys a season; lining the pipe ends it.

Water softener install. They tested our water first rather than just selling a unit, and sized it accordingly. Fixtures have stayed clean since.

Called at 6am about no water in the house. Frozen line at the meter. He talked me through what to do while he drove over. Sorted by 8.

Backflow Testing in Rock Valley: common questions
How often does a backflow device need testing?
Annually in most Rock Valley 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 Rock Valley, 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 serve the smaller towns around Rock Valley?
We do. Our Rock Valley coverage extends through the surrounding communities, and we run across the whole state, so being outside the city limits does not mean waiting longer or paying a travel premium.
