Tempe homeowners call Liberty for backflow prevention & testing because we're local to the Valley, licensed, and answer the phone 24/7. Tempe is an established East Valley city, mid-century and 1970s-80s homes near ASU with newer infill scattered through. That older housing stock means galvanized and aging-copper repipes, sewer-root work, and plenty of rental-property plumbing. We've done a lot of it. When we look at your place, you'll get the truth about what's failing, your options laid out plain, and a fair price upfront before we start.

Tempe's plumbing reality is defined by age and turnover. The neighborhoods ringing ASU, from the mid-century ranches near downtown to the 1970s and 80s builds in south Tempe, were plumbed with galvanized steel and early copper that's now corroding from the inside out. Galvanized lines clog with rust until pressure drops to a trickle, and we still pull original galvanized out of Tempe homes weekly. Add decades of rental turnover, where deferred maintenance compounds because no owner-occupant catches the slow problems, and you get homes where a single repipe finally resolves years of mystery low-pressure and discolored-water complaints.

What we see on Tempe plumbing

  • Galvanized and aging-copper supply lines needing repipe

Backflow Prevention & Testing in Tempe, 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.
My older Tempe home has low water pressure everywhere, what's wrong?
That's the classic signature of galvanized supply lines rusting shut from the inside, common in Tempe's mid-century and 1970s homes. The corrosion narrows the pipe until flow drops at every fixture. A camera and pressure test confirms it, and a repipe to PEX or copper restores full pressure for good.
