Backflow Testing in Henderson, CO

Signs you need a backflow visit

• Your water provider has sent a test notice for a backflow assembly
• A sprinkler device leaks or sprays after start-up
• A tester told you the device failed
• You're adding irrigation, a livestock line or another connection that needs protection
• You're not sure whether your property has any backflow protection at all

What's known about water and backflow in Henderson

Henderson is an unincorporated community along Brighton Road north of 120th Avenue, and much of the land around it has been annexed by Commerce City, Brighton and Thornton. That's why the water provider varies by address. The fact sheet could not pin down a single provider: annexed parcels may be on the system serving Commerce City, Brighton or Thornton, each with its own rules, and Hazeltine Heights Water and Sanitation District, a small domestic water district with a Henderson mailing address, serves some homes.

Where the sheet does have detail, it's about responsibility. Hazeltine Heights makes its customers responsible for the service line from the downstream side of the meter pit to the home and for any required backflow or cross-connection devices. Other providers may set their own testing schedules, so the right move is to find the provider on your water bill and ask about its program, or ask Adams County if you're unsure.

Permits follow the same split. Unincorporated addresses go to Adams County's One Stop Permitting Center, while annexed parcels fall under the city that annexed them. Henderson's plains location also means hard freezes, so outdoor devices need fall draining.

Cost factors

• Which program applies. Some providers require annual tests and filed reports; that adds paperwork to the visit.
• Device condition. Worn checks and relief valves mean a rebuild and retest.
• Replacement. Freeze-cracked bodies usually get replaced.
• Permit office. Adams County or the annexing city may need a permit for new work.

When you call

An independent plumber who serves Henderson will ask who supplies your water and what the device protects. Have your water bill and any notice from the provider nearby, since that decides where the test report goes. If you can't find a device at all, say so; the plumber can look at the sprinkler tie-in and the main shutoff area and tell you whether protection is missing.
