Backflow Prevention & Pressure Control
Protect Water Quality and Keep Pressure Under Control
Oasis Plumbing Solutions evaluates, repairs, replaces, and installs selected backflow-prevention, pressure-reducing, shutoff, and water-pressure components for homes, businesses, managed properties, and construction projects throughout Tucson and Southern Arizona.
Water-Control Services
Different Devices Solve Different Water-System Problems
High pressure, unstable pressure, reverse-flow risk, a leaking assembly, a failed shutoff, and a damaged vacuum breaker are not interchangeable conditions. The correct scope depends on the property, device type, application, jurisdiction, water provider requirements, and the condition of the surrounding piping.
Water-Pressure Evaluation
Selected pressure checks and system observations to help identify abnormal conditions.
- Static pressure
- Operating-pressure observations
- Pressure fluctuation concerns
- Accessible system review
Pressure-Reducing Valves
Evaluation and selected replacement or installation of accessible PRVs.
- Residential PRVs
- Light-commercial applications
- Pressure adjustment by scope
- Upstream/downstream isolation
Backflow Assembly Replacement
Selected replacement or installation when device type, sizing, access, and authorization are confirmed.
- PVB applications
- Selected DC or RP assemblies
- Unions and isolation valves
- Freeze and support considerations
Vacuum Breakers & Anti-Siphon Devices
Selected protection at hose connections and applicable fixture or irrigation points.
- Hose-bibb vacuum breakers
- Anti-siphon components
- Damaged-device replacement
- Application review
Main Shutoffs & Control Valves
Accessible valves that support isolation, maintenance, and pressure-control work.
- Full-port shutoffs
- Device isolation valves
- Unions and transitions
- Irrigation tees by scope
Commercial & Project Support
Selected installation, repair, replacement, and coordination for larger or regulated applications.
- Approved device schedules
- Utility requirements
- Shutdown coordination
- Testing coordination
Pressure Control
High Water Pressure Can Affect the Entire Property
Excessive or unstable pressure may contribute to noisy piping, short fixture life, leaking supplies, damaged valves, nuisance relief-valve discharge, and repeated failures. A PRV is one possible component of the solution, but the system should be evaluated as a whole.
Two Separate Functions
Pressure Regulation Is Not Backflow Prevention
Pressure-Reducing Valve
- Reduces incoming water pressure
- Helps maintain a selected downstream pressure
- Does not substitute for a required backflow assembly
- May require thermal-expansion considerations
Backflow-Prevention Device
- Helps protect against unwanted reverse flow
- Device type depends on hazard and application
- May be regulated by a water provider or jurisdiction
- Testing requirements vary by device and location
Service Process
From Symptoms and Requirements to a Defined Scope
Identify the Device
Review application, size, manufacturer, model, location, symptoms, and available records.
Confirm Requirements
Determine applicable utility, jurisdiction, testing, permit, access, and shutdown requirements.
Complete Authorized Work
Repair or replace selected piping, valves, PRV, or backflow components within the agreed scope.
Verify & Coordinate
Check accessible operation and coordinate required qualified testing or documentation when applicable.
Pressure & Backflow Questions
Important Information Before Scheduling
How do I know whether my pressure is too high?
A pressure measurement is the starting point. Symptoms alone are not conclusive, and pressure can vary with time, demand, supply conditions, and equipment operation.
Does replacing a PRV fix every pressure problem?
No. System pressure may also be affected by municipal supply, thermal expansion, closed-system conditions, shutoffs, pipe sizing, equipment, restrictions, or other components.
Can Oasis replace a backflow assembly?
Selected assemblies can be replaced or installed after the application, sizing, access, authorization, device requirements, and required follow-up testing are confirmed.
Does Oasis provide certified backflow testing?
Only when the assigned technician and Oasis hold every qualification, authorization, and registration required for that jurisdiction and application. Otherwise, we can define installation or repair scope and coordinate with an appropriately qualified tester.
Protect the System
Concerned About Water Pressure or a Backflow Device?
Send the property location, symptoms, device photos, pipe size, manufacturer and model when visible, and any notice from the water provider or jurisdiction.
