Backflow testing is required by law, and it is there to protect your water supply
Bay Area water districts require annual backflow testing for a reason
Backflow prevention devices are installed on properties where there is a risk that contaminated water could flow backward into the municipal water supply. This includes homes with irrigation systems, fire sprinkler systems, swimming pools, and most commercial properties. San Mateo County water districts require that these devices be tested annually by a certified tester. If testing is overdue or the device fails, you may receive a compliance notice or face penalties.
We test, certify, repair, and file the paperwork
Our certified backflow testers handle the entire process. We test the device, provide the results, file the required certification paperwork with your water district, and if the device fails, we repair or replace it on the spot.
Stay ahead of compliance deadlines
Most property owners receive a notice from their water district when testing is due, but it is easy to let the deadline slip. We can put you on a recurring schedule and send you a reminder so you never have to worry about missing a deadline or receiving a violation notice.
What to expect before, during, and after a water softener installation
Before
We schedule your test at a convenient time and confirm the location of your backflow prevention device. If you are unsure whether your property requires testing, we can check your water district’s records and let you know.
During
Our certified tester connects pressure gauges to your backflow device and runs it through a series of standardized tests to confirm it is preventing backflow correctly. The process takes about 30 to 60 minutes. If the device fails, we diagnose the issue and can usually repair it during the same visit.
After
Once testing is complete, we provide you with the results and file the required certification paperwork with your water district. If repairs were needed, we document those as well. We can also set you up on a recurring schedule so you are always ahead of the next deadline.
6 Reasons to Schedule Backflow Testing
You Received a Notice From Your Water District
If your water district has sent a testing notice or compliance reminder, your device is due. Testing is required and failing to respond can result in penalties or water shutoff.
Your Property Has an Irrigation System
Homes and businesses with in-ground sprinkler systems are among the most common properties that require backflow prevention and annual testing.
You Own a Commercial Property
Most commercial properties in San Mateo County are required to have backflow prevention devices tested annually, regardless of the type of business.
Your Property Has a Fire Sprinkler System
Fire suppression systems are connected to the water supply and typically require dedicated backflow prevention and regular testing.
You Have a Pool or Hot Tub
Properties with swimming pools, hot tubs, or spa systems that are connected to the municipal water supply may require backflow testing.
It Has Been More Than a Year Since Your Last Test
Annual testing is the standard requirement. If it has been more than 12 months, you are likely overdue and should schedule a test before your water district follows up.
