Frequently Asked Questions About Backflow Preventer in Stockton
Annual residential backflow testing typically costs $75 to $150 per assembly. Repairs with a rebuild kit usually run $150 to $450. New residential installation ranges from $300 to $1,200, and commercial RPZ assemblies often cost $1,500 to $5,000 installed.
No, backflow preventer installation and major repairs should only be performed by a licensed and certified plumber. Improper installation or repair can lead to water contamination, which poses serious health risks and can result in significant fines from local authorities. Special tools and training are required.
FBL Plumbing stands behind our work with a full warranty on parts and labor for all backflow preventer services. The warranty period will be outlined in your service agreement, but generally, new installations come with a manufacturer's warranty on the device and our warranty on the labor.
Backflow prevention is crucial because of changing water pressures, main breaks and fire flow that can drop pressure suddenly, and the potential for cross-connections from irrigation systems or industrial processes. These factors increase the risk of contaminated water entering the public supply, making a working backflow preventer essential.
Constant dripping from the relief valve, low water pressure and visible cracks are common signs. Discolored water or a failed test notice also indicate a problem. Prompt repair keeps you in compliance.
A well-maintained backflow preventer can last 10 to 20 years or more. However, factors like water quality, exposure to weather, and the type of device can affect its lifespan. Mountain and foothill homes in Northern California see real winters, so pipes there need insulation, heat tape, or careful draining when a cabin sits empty. Regular testing and maintenance help lengthen its service life.
New installations and replacements often require a plumbing permit and an initial test. Requirements vary by city and water provider. We obtain permits and handle the initial test.
Yes. Parts carry the manufacturer warranty and our workmanship is guaranteed. Every repair is retested to confirm it passes before we leave.
