Backflow Prevention in Crystal Lake, IL

The Vital Purpose of Backflow Prevention Devices

Backflow occurs when contaminated water flows in the wrong direction, re-entering your home’s clean water supply from the sewer, irrigation system, or other external sources. This can happen during sudden pressure changes in your plumbing system and may introduce harmful bacteria, chemicals, or debris into your drinking water. That’s why backflow prevention devices are so important, they act as a one-way gate, ensuring water only flows into your home, never out and back in.

At Althoff Home Services, we install, test, and repair backflow preventers to keep your home’s water supply safe and up to code. We’ve been protecting homes in Crystal Lake and the surrounding suburbs for decades with proven expertise and trustworthy service. Whether you’re required to install a device or want to take proactive safety measures, our team ensures your system is secure and compliant.

Not All Homes Have Backflow Preventers. Does Yours?

Not every home is equipped with a backflow prevention device, and depending on your plumbing layout, you may be more at risk than you realize. Homes with irrigation systems, private wells, or pressure-based systems are especially susceptible to backflow. If you’re unsure whether your home is protected, Althoff Home Services can perform a simple inspection to find out.

We evaluate your home’s plumbing connections and water usage points to determine if a backflow device is present, functioning, and located where it should be. If installation is needed, we’ll guide you through your options and install the appropriate type of backflow preventer for your system. We always provide quotes before performing service, so you can make informed decisions. With our 100% satisfaction guarantee, you can trust that your water quality is in good hands.
