Mountainaire homeowners call Liberty for backflow prevention & testing because we're local to the high country, licensed, and answer the phone 24/7. Mountainaire sits at about 6,950 feet in the pines south of Flagstaff, taking in the Mountainaire and Kachina Hills subdivisions. Out here it is mostly wells, septic, and cabins that sit empty part of the year, so freeze protection and winterization are the bread and butter. Real licensed crew, straight answers, fair quote before we touch a thing.

Mountainaire runs right up against the Coconino National Forest at close to 6,952 feet, and the housing is a mix of full-time homes and part-time places in the pines. Unlike neighboring Kachina Village, most of Mountainaire is not on a water and sewer district, which means private wells, pressure tanks, and septic systems doing the work. Every one of those adds freeze-prone components outside the heated envelope of the house, and at this elevation the freeze season is long enough that a shallow or uninsulated run will eventually find its limit.

What we see on Mountainaire plumbing

  • Deep winter freezes at nearly 7,000 feet on well lines, hose bibs, and unheated crawlspace plumbing.
  • Private wells and septic systems that need the plumbing side maintained on both supply and drain.

Backflow Prevention & Testing in Mountainaire, FAQ

Who requires backflow testing?
Most Maricopa County water providers require it every year for irrigation, pools, and commercial connections.
Can you file the paperwork?
Yes, we submit the certification straight to your provider.
Why did I get a notice saying my backflow needs testing?
Most Arizona water providers require an annual certified test on backflow assemblies, usually on irrigation systems and commercial connections, to protect the public water supply. We do the certified test and file the results straight with your water purveyor, so you stay compliant.
What happens if I ignore the backflow test deadline?
Depending on your provider, you can face fines and, in some cases, water service shutoff until the assembly is tested and compliant. The test itself is quick, so it's not worth the risk. We can test and submit the paperwork before the deadline passes.
My backflow device failed the test. Do I have to replace the whole thing?
Not always. Plenty of assemblies are rebuildable. We install the manufacturer's repair kit (new check rubbers, springs, relief parts) and re-test it to pass, and that's a lot cheaper than replacement. We only swap the full assembly when the body is freeze-cracked or too corroded to rebuild.
Why does my backflow keep failing every year?
Hard Valley water scales the internal rubber and seats, so a check that sealed last year stops seating this year. That's the whole reason testing is annual. A device near the end of its service life will fail more often, and at that point replacement is the better value than rebuilding it again and again.
Do I need to protect my backflow in winter?
In the high country, no doubt. Above-ground assemblies in Flagstaff and Prescott freeze and commonly crack the brass body or bonnet over winter, which means a rebuild or replacement come spring. An insulated cover and a proper seasonal shutdown of the irrigation line head off an expensive freeze failure.
I leave my Mountainaire place empty over the winter. What should I do?
Winterize it, and do not rely on leaving the heat set low and hoping. We drain the system, blow out the supply lines, protect the traps with antifreeze, and shut it down properly so there is no water sitting in a pipe at 6,950 feet in January. Come spring we bring it back up and check every line and fixture for damage before you turn it over to a house full of guests.
