THE PROCESS
How Backflow Testing Works
Once you call, we take care of everything. From confirming your assembly details to testing and submitting results, our process is designed to simplify this annual requirement without added stress or paperwork.
Step 1: Call & Confirm
Call us for a free consultation.
We confirm what is required, answer questions, and schedule your test.
(You do NOT need your letter, but having it helps.)
Step 2: Test & Notify
A certified technician completes your test.
Exterior tests do not require you to be present. Interior tests are scheduled with a clear time window and text updates.
Step 3: Submit & Confirm
We submit the report directly to your water provider.
You receive your report and confirmation of compliance. No paperwork. No follow-ups. No confusion.
Step 4: Relax & Repeat
After your first test, you are set up for easy future visits.
We track future tests and notify you ahead of time. Just confirm your property and service. We take care of the rest.
