Why Do Backflow Problems Occur?
Your plumbing system is designed to move water in one direction only. But under certain conditions—like sudden drops in water pressure—water can reverse its flow. This backflow can allow contaminants like sewage, pesticides, or bacteria to mix into your clean water supply.
To stop this from happening, backflow prevention devices are installed. But over time, these systems can wear out, malfunction, or break. That’s where our licensed plumbers come in.
What Are Some Common Prevention Devices?
There are several effective systems out there to help prevent backflow problems in your home’s plumbing. Here are some of the most common ones:
Reduced pressure backflow preventers – These are widely used and super reliable. They work by releasing excess water when backflow is detected, helping to relieve pressure and prevent any cross-contamination in your water supply.
Double check valve systems – These come with two spring-loaded check valves that automatically test themselves from time to time to stay in good working condition. If any backflow occurs, they kick into action to keep your drinking water safe.
Pressure vacuum breakers (PVBs) – These compact devices detect pressure changes and quickly vent out any contaminated water before it can mix with your clean supply. They’re great for protecting your water lines without taking up much space.
At plumbersanjose, our experienced plumbing team specializes in San Jose backflow installation services. We’ll help you choose the right device for your setup and make sure it’s properly installed, so your home’s water stays clean, safe, and worry-free.
