Backflow Repair Experts
Repair or replace backflow prevention devices to protect your water supply and stay compliant.
Chapter 01
Contaminated water going the wrong way
Backflow is contaminated water flowing backward into your clean water supply. A backflow prevention device is the check that stops it. It can fail from age, debris, or a damaged seal, and when it does the only outward sign may be a leak at the device or uneven pressure in the sprinkler system.
Because the risk is to the drinking water, a failing device is different from a leaking spigot. The cost of waiting is not measured in wasted water alone. That is why repair and replacement are about protecting your water supply and staying compliant, not routine maintenance that can slide.

Repair when it can be repaired, replace when it fails
Replacement is needed when the device fails testing or is no longer functioning properly, while many devices can be repaired depending on the issue. In practice, a device with a fixable problem gets repaired, and one that fails testing or has stopped working gets replaced.
When you call (479) 278-4508, tell the office what type of device you have, where it sits, what you noticed, and whether a test recently failed. Say whether you own the property. Allied can't schedule service directly with renters, so a tenant should ask the property owner or property manager to contact the office and book.
Chapter 03
Why Allied recommends repairing quickly
Repairing quickly is important to prevent contamination risks. A failed device can put clean water at risk, and a device that has failed a required test may leave a property out of compliance until it is fixed or replaced, which is why speed matters more than usual.
