Called about a gas smell near the water heater. They told me to get out of the house first and call the utility, then came and found it. Took it seriously, which I appreciated.

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

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.

Reliable is the main thing. Third time we have used them across two houses and it has been the same experience every time.

Backflow Testing in Dyersville: common questions
How often does a backflow device need testing?
Annually in most Dyersville 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 Dyersville, 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 tell me what is wrong over the phone?
Often we can narrow it down, and sometimes we can tell you it is something you can fix yourself in five minutes. We would rather do that than send a truck you did not need.
