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

Well water changes what you need
Homes outside the Davenport municipal supply often deal with iron and sulphur alongside hardness, and a plain softener will not handle all three. We test before recommending anything, because the wrong equipment on well water either fails early or does nothing.

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.

Old galvanised pipes giving us brown water every morning. They repiped in PEX and explained the trade-offs against copper honestly instead of just pushing one.

Backflow Testing in Davenport: common questions
How often does a backflow device need testing?
Annually in most Davenport 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 Davenport, 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 charge extra for nights and weekends in Davenport?
No. A call at 2am on a Sunday costs the same as the same job at 2pm on a Wednesday. No overtime rate, no holiday surcharge, no emergency premium.
