Backflow Repair in Dallas–Fort Worth

When an assembly fails its test or starts discharging water, it needs to be rebuilt or replaced before it can be certified again. Freeze damage is a common cause here, since most irrigation assemblies sit above ground.

A failed assembly is also a water-waste problem — a discharging relief valve can run continuously.

Symptoms and problems

• • A failed test report
• • Water continuously discharging from the relief port
• • A cracked body or bonnet after a freeze
• • Visible corrosion or leaking at the assembly

Common causes

• • Freeze damage from an uninsulated assembly
• • Debris holding a check valve open
• • Worn springs, seats, and seals
• • Excessive supply pressure

Typical solutions

• • Rebuilding the assembly with a manufacturer repair kit
• • Replacing the assembly when the body is damaged
• • Insulating or protecting it against future freezes
• • Retesting and refiling the certification

When to get professional help

Repairs on backflow assemblies must be followed by a certified test before the device is considered compliant.
