Backflow Preventer Installation
The Right Device, Placed Right
Adding irrigation, opening a business or told you need backflow protection? Our plumbers install backflow preventers matched to your hazard level, sized for your flow and tested on completion.
Backflow Preventer Installation Matched to Your Hazard Level
The first question in any backflow preventer installation is what the device needs to protect against. A lawn sprinkler system, a restaurant’s soda machine, a dental office, a commercial boiler and a fire sprinkler line all present different risks. Codes and water utilities classify connections by degree of hazard and specify acceptable assembly types. Installing the wrong type can fail inspection, leave drinking water unprotected or require costly replacement once your utility reviews the installation.
Size matters just as much. A backflow assembly creates some pressure loss as water passes through its check valves, and reduced pressure assemblies typically lose more than other types. An undersized assembly can noticeably reduce flow to sprinklers, fixtures and equipment, while an oversized one adds unnecessary cost. Our plumbers confirm the required assembly type with your utility or local code, size it for your flow and pressure and choose an approved model from a recognized list.

Placement Rules That Matter for a New Backflow Preventer
Where an assembly goes affects whether it works, whether it can be tested and whether it passes inspection. Reduced pressure assemblies discharge water from their relief valves when a check fails or pressure fluctuates, so they must be installed above ground, never in a pit that could flood, and where discharge can drain safely. Indoors, that means a floor drain or air gap fitting sized for the potential discharge, which can be substantial.
Pressure vacuum breakers must sit above the highest downstream outlet, such as the highest sprinkler head, to work correctly. Every assembly needs enough clearance around it for testers to connect gauges and for technicians to make repairs. Shutoff valves and test cocks must be accessible. Assemblies should also be protected from vehicle traffic, landscaping equipment and freezing. We plan placement around these rules and your property layout before installation begins.

Benefits of Professional Backflow Installation
Professional installation ensures your backflow preventer is the correct type for your hazard, meeting utility and code requirements the first time. Correct sizing protects water pressure for sprinklers, fixtures and equipment. Proper placement makes annual testing quick and repairs easier. Drainage planning prevents water damage when RP relief valves discharge. And including the initial test and paperwork means your new assembly is approved and in service without delays or extra appointments.

Protecting Backflow Assemblies From Freezing and Theft
Outdoor backflow assemblies face two common threats that can leave you with an expensive replacement and a failed compliance status. Both are preventable.
Even in mild climates, occasional hard freezes can crack brass bodies and damage internal parts in exposed assemblies. Insulated covers, heat tape or heated enclosures protect assemblies during cold snaps. Irrigation assemblies can also be drained before freezing weather when the system isn’t needed for watering.
Brass backflow assemblies are also targeted by thieves for scrap metal value, especially at commercial properties. Lockable steel cages or enclosures, anchoring and security hardware make theft much harder. We’ll recommend protection suited to your location, climate and risk, and install it alongside your new assembly.
How Our Backflow Preventer Installation Works
We review the connection being protected, confirm required assembly type with your water utility and measure flow and pressure needs.
You’ll receive a recommendation for the assembly model, size, location, enclosure and price. After permits are issued, water is shut off and the assembly is installed with shutoff valves and test cocks, at the correct height and clearance, with drainage provided for RP relief discharge.
Water is restored slowly, and the assembly is flushed and checked for leaks. A certified tester performs the initial test, and results are submitted to your utility. Required inspections are completed, enclosures or freeze protection are installed and we add the assembly to your annual testing reminder schedule.

Backflow Preventer Installation Questions Answered
Which backflow preventer do I need?
It depends on the hazard and local requirements. We confirm the required assembly type with your water utility before installation.
Does a backflow preventer reduce water pressure?
Some pressure loss is normal. Proper sizing and model selection minimize the effect on sprinklers, fixtures and any equipment downstream.
Can an RP assembly go in a pit?
No. Reduced pressure assemblies must be installed above ground, since a flooded pit could allow contaminated water to enter through the relief valve.
Is a permit required for installation?
Often yes. Many jurisdictions require permits and inspections for new backflow assemblies, plus an initial test by a certified tester.
How do I protect against freezing?
Insulated covers, heated enclosures or draining irrigation assemblies before freezing weather protect brass bodies and internal parts from costly damage.
