Certified backflow assembly testing/installation and pressure-reducing valve service to protect your water supply and plumbing system.

Backflow devices protect your drinking water from contamination, while pressure regulators protect your pipes, water heater, and appliances from damaging high pressure. We install, repair, and certify backflow prevention assemblies and pressure-reducing valves to keep your system safe and code-compliant.
We test your current backflow assembly or measure static water pressure at the meter.
You'll get a straightforward explanation of what's needed and why, with pricing upfront.
We install or service the assembly/PRV to current plumbing code.
Final testing is performed and paperwork is filed with your water provider when required.
Municipal water pressure above 80 psi can stress pipes, fittings, and appliances, leading to premature failures. A PRV keeps household pressure in a safe, efficient range.
Many California municipalities require annual backflow assembly testing for irrigation systems and certain commercial connections. We handle testing and can help with the paperwork.
Sudden spikes in pressure, banging pipes (water hammer), or a noticeable pressure drop are common signs it's time for a replacement.

Replace old, corroded galvanized or polybutylene pipes with durable copper or PEX for better pressure, cleaner water, and fewer leaks.
