We test, repair and rebuild backflow assemblies for homes, HOAs and commercial properties, and we handle the paperwork so the report reaches the district in the form it expects. A failed test isn't a problem if it's fixed and retested before your deadline.
When you need backflow service
- A test notice from EID, or an annual test deadline you can't find the last report for
- Water spraying or dripping from the relief valve of a backflow assembly
- A new irrigation system, fire sprinkler line or commercial build-out that needs an assembly
- A failed test result that requires repair and a certified retest
- A preventer cracked by a winter freeze or damaged by a mower or vehicle
- Low water pressure traced to a fouled or stuck check valve
- A commercial lease or inspection requiring current backflow certification
What's included
Every backflow testing & repair job in El Dorado Hills covers the essentials below — no vague scopes, no surprise add-ons:
- Identification of every backflow assembly on the property and its type
- A certified test using a calibrated gauge, performed to the standard for that assembly
- A completed test report submitted to the water district in its required format
- Cleaning and inspection of check valves, relief valves and shutoffs
- On-the-spot repair or rebuild with the correct parts if a component fails
- A certified retest after any repair, with the passing report filed
- A copy of every report for your records, and a reminder before next year's deadline
How a backflow test and repair works
- 1
Identify the assembly
We confirm the type: pressure vacuum breaker, double check valve or reduced pressure zone. Each is tested differently.
- 2
Run the certified test
With a calibrated gauge we measure each check valve and relief valve against the pass thresholds for that assembly.
- 3
Report the results
If it passes, we complete the test report and submit it to the district in the format the water purveyor requires.
- 4
Repair what failed
Fouled seats, worn discs, torn diaphragms and broken springs are rebuilt or replaced. If the body is cracked, we replace the assembly.
- 5
Retest and file
A repaired device is retested to prove it passes, and the passing report goes in. You get a copy for your records.
Why the district cares
Your plumbing and irrigation are connected to the same public water system your neighbors drink from. If pressure in the main drops, a break or heavy fire-fighting draw can reverse flow, and anything sitting in your lines can move toward the supply. A backflow assembly is the mechanical barrier that stops that.
Those barriers are only reliable if they're tested. Rubber seats harden, springs fatigue, and debris holds check valves open. Annual testing catches a device that's quietly failed before it matters, which is why the water district treats it as a requirement rather than a suggestion.
Homes, HOAs and commercial properties
Homeowners usually have a single assembly on the irrigation line, often a pressure vacuum breaker standing above ground. HOA common areas and commercial properties may have several, and some, such as fire sprinkler and process-water connections, call for a reduced pressure assembly that is more involved to test.
For property managers we keep the list of assemblies, test dates and results, so nothing lapses. If you manage multiple sites, one visit can cover every assembly on the property.
Freeze, mowers and age: what damages assemblies here
Above-ground backflow assemblies are exposed. In the foothills a hard freeze can crack a body that wasn't drained or insulated, and the freeze risk grows with elevation. Mowers, vehicles and string trimmers knock assemblies out of alignment or break them outright.
Even a protected device ages. Seats harden and springs weaken. If the assembly is old enough that parts are discontinued, replacing it is often smarter than repairing it again.
Choosing the right assembly for new work
A new irrigation system, fire line or commercial build-out has to use the assembly the hazard level calls for. A pressure vacuum breaker works for many residential sprinklers, while a double check or reduced pressure assembly is typical where the hazard is higher or the equipment is below the point of use.
We help property owners and contractors pick, install and register the right device, so the first annual test is a formality and not a surprise correction.
What affects the price
We use upfront, flat-rate pricing and give you the number before we start — no fake fixed quotes online, because the honest answer depends on your home. For backflow testing & repair in El Dorado Hills, the main factors are:
- Number and type of assemblies on the property
- Whether the device passes or needs repair parts
- Assembly size and accessibility, such as vaults or tight utility rooms
- Repair versus full replacement when the body is damaged or obsolete
- Freeze or impact protection added to above-ground assemblies
- Multi-site or recurring service for HOAs and property managers
