Picking the right preventer comes first. We look at how the water is used, check your district's requirements, size the device for your flow, and then install it so it can be tested every year.

Matching the device to the risk
What could flow backward into the water supply determines which preventer you need. Water districts sort connections by hazard and approve specific devices for each.
High-risk uses, including clinics, dental offices, car washes, chemical injection and many restaurants, usually need an RP or an air gap. Lower-risk connections, like many fire sprinkler services, can often use a double check. Sprinkler systems exposed only to backsiphonage may use a PVB or SVB.
The district decides. We check its requirements for your connection before quoting, so the device we install is one they'll accept.
Picking the right size
A backflow preventer has to be big enough to pass the water your property uses without dropping pressure too much. Every device causes some pressure loss, and an undersized one can leave upstairs fixtures weak or sprinklers sputtering.
We look at the pipe size, the peak water demand and the pressure available at the meter. For most homes in Riverside, that points to a 3/4-inch or 1-inch device. Commercial buildings and fire lines often need 2 inches and up.
Bigger isn't always better either. An oversized device costs more, takes more space and can be harder to keep passing. We size it for what you actually use.
Paperwork before the install
Requirements vary. Some districts want plans before a commercial install. Others just need the first test report afterward. Cities may ask for a plumbing permit, particularly on commercial and fire line work.
We'll let you know what applies to your job and build it into the schedule. Permits, when needed, are part of the plan from the start.
Once the device is in, we test it and file the first report, which adds it to the district's records and starts the yearly testing cycle.
When people need a new device
New buildings are the most common reason. Commercial projects and homes with new irrigation usually need protection before the water service is signed off.
Adding equipment is another. Installing sprinklers, a pool, a boiler or a fire sprinkler line often brings a new requirement. Changing how a space is used, like store to restaurant, can too.
Other times a district review finds an unprotected connection. In every case, we confirm the right type, size it, install it and file the first test report.
Preventers for sprinkler systems
Irrigation is one of the top reasons for a new preventer. The right type depends on the district and the system: PVB, SVB, double check, or RP if fertilizer or chemicals will be injected.
We consider the slope of the property, valve locations and any planned chemical feed before recommending a device and spot.
Larger preventers
Commercial installs often involve larger devices, plans, permits and coordination with general contractors or fire sprinkler contractors. Fire lines typically use detector assemblies sized 4 inches and up.
We work with your contractor and schedule so the preventer goes in at the right point in the project, and the startup test is done before final inspection.
What a quote includes
Our quotes spell out the device type and size, labor, any piping or fitting work and optional extras like a cage or cover. The startup test and the first district report are included.
When a permit is required, the quote says so. Quotes are free, and you'll see the full price before anything is scheduled.
If you suspect an existing device is the wrong type, we can compare it to your district's rules and tell you whether it should be replaced or is fine as is.

Questions
Is installation priced up front?
Yes. You get a free quote after we look at the site.
Will the district add the new device to its records?
Yes. Filing the first test report puts it on their list and sets the first annual due date.
Do you pull permits?
When a permit is required, we let you know and include it in the plan.
Can I install a PVB instead of an RP to save money?
Only if your district allows it for your hazard. For high-hazard uses, an RP is usually required.
Can the wrong size cause problems?
Yes. Too small can drop pressure, and too big can cost more and be harder to keep passing.
Will my district need to approve it?
Many do. We check the requirements and handle the paperwork with you.
