Shower had been running cold randomly for months. Turned out to be the balancing cartridge, not the whole valve like another company told us. Fixed in under an hour.

Older sewer lines here are clay or cast iron
Plenty of Decorah homes still run their waste out to the street through clay tile with a joint every few feet, and roots find every one of them. Cast iron scales shut from the inside instead. Either way, a main line that backs up twice in a year is telling you something a camera can confirm in twenty minutes.

Toilet had been running for who knows how long. Quick visit, new flapper and fill valve, and my water bill dropped noticeably the next month. Wish I had called a year earlier.

Called on Christmas Eve about a frozen pipe. Fully expected a holiday surcharge and there wasn't one. Same price as any other day, which I did not expect and have not forgotten.

Backflow Testing in Decorah: common questions
How often does a backflow device need testing?
Annually in most Decorah 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 Decorah, 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 have a plumber available in Decorah right now?
Almost always. Our Decorah line is answered around the clock, including nights, weekends and holidays. Call (833) 435-9778 and we will tell you honestly how soon a truck can be at your address rather than giving you a vague window.
