Common reasons for repair

A backflow assembly may need repair when internal parts wear out, seals dry out, springs weaken, or debris keeps the check valves from closing properly. Damage from freezing, corrosion, high water pressure, or accidental impact can also affect performance. Even if the assembly is still in place, these issues can cause leaks, pressure loss, or failed operation.

What to look for

  • Visible leaks around the body or test ports
  • Water dripping from the relief port on an RPZ assembly
  • Erratic pressure or inconsistent flow
  • Signs of corrosion, cracking, or physical damage
  • Repeated test failures after adjustments

If you notice any of these problems, Dallas Landscape & Irrigation can evaluate the assembly, explain the needed repair, and restore it to working condition when possible. Prompt service helps protect your irrigation system and reduce the risk of water contamination.
