Most homeowners first hear about their backflow device when a notice shows up. It's usually on the sprinkler line, the main water line, a pool fill or a fire sprinkler service. We find it, test it and handle the filing.

Why your water district knows about your device
If you've never heard of a backflow device before getting a notice, you're not alone. Water districts keep records of every device in their area, typically added when the device was installed or when a property was reviewed.
A device is needed wherever water from your property could be pulled or pushed back into the public system. Irrigation, pools and spas, wells, home fire sprinklers and plenty of commercial setups qualify.
The record stays with the property, not the owner. If you bought the house recently, the device and its yearly due date came with it. The district will keep sending reminders until a passing report is on file each year.
What to do when the notice arrives
Look at two things first: the due date and how many devices are listed. Larger properties sometimes have several, each due separately.
Next, call or schedule online. If you have the notice nearby, it helps, since it usually shows the device size, serial number and where it's located. If it's lost, we can still find the device when we arrive.
We submit the report to your district when the test is done, so there's nothing to mail. If a repair is needed, you'll get the price before we start. For more about what's on the letter, see our guide to backflow test notices.
Getting ready for the tester
You usually don't need to be home for a residential test as long as we can reach the device. A few small things help the visit go quickly.
Make sure we can get to it. If it's behind a locked gate, share the code or unlock it for the day. Keep dogs inside. If the device is buried in bushes, trimming them back saves time.
Turn off any automatic sprinkler schedule that would run during the appointment window. And let us know if the device is in a box that floods, has a cage with a lock, or sits somewhere unusual. With that, most residential tests are done in well under an hour, and you'll get the report by email.
What it costs and what's included
It's a flat $105 per device under 4 inches, which covers almost every home device out there. Devices 4 inches and up are $175, mostly found on commercial and fire lines.
That price includes coming out, running the test and submitting the report to your district. No filing fee, no surprise add-ons.
If a repair is needed, you'll get a price before any work starts, and the retest after the repair is included. Want to skip the reminder letters next year? Our due date management service will contact you before the device is due again.
Who's responsible at a rental
At rental properties, the water district usually sends notices to the property owner or the account holder on file. Most leases put backflow testing on the owner, but some commercial leases shift it to the tenant.
If you're a tenant and a notice lands in your mailbox, pass it to the owner or manager. If you're a landlord, we can coordinate access with your tenant directly so you don't have to be there.
Pools, wells and home fire sprinklers
Most home devices protect sprinkler systems, but pools and spas with auto-fill lines often have one too. Homes with a private well or a residential fire sprinkler system usually do as well.
They're tested the same way, every year, at the same flat price by size. If your notice mentions a device you can't locate, check near the pool equipment, the well or the fire sprinkler riser.
Still not sure where it is?
We'll locate it on the visit. Here's what your notice means.
Questions
Do I need to be home?
Not if we can reach the device. A gate code and a phone number are usually enough.
Can I test it myself?
No. Districts only accept reports from certified testers with calibrated gauges.
I just bought the house. Is the test my responsibility?
Yes. The device and its due date stay with the property, so the new owner takes over the yearly test.
What does it cost?
$105 per device under 4 inches. Most homes fall in that range.
Why does my house have a backflow device?
Usually because of irrigation, a pool, a well or a fire sprinkler line. Your district requires one wherever water could flow back into the public supply.
What if I have more than one device?
Each one needs its own test and report. We can do them all on the same visit.
