As a homeowner, you want to ensure that your family has access to safe and clean water. However, there are certain issues that can compromise the quality of your water supply, such as backflow.

Backflow is the reverse flow of water from a contaminated source into your home’s clean water supply. This can happen when there is a sudden drop in water pressure or a backflow event in the municipal water supply. In this blog post, we will discuss the importance of backflow prevention in your home and how to ensure that your water supply remains safe and clean.

What is Backflow?

Backflow occurs when there is a reversal in the flow of water from its intended direction. This can happen when there is a sudden drop in water pressure, which can cause water to flow in the opposite direction. Backflow can also occur when there is a backflow event in the municipal water supply. This can happen when there is a break in a water main or when there is a sudden increase in demand for water.

Why is Backflow Prevention Important?

Backflow can compromise the quality of your water supply by allowing contaminated water to flow into your home’s clean water supply. This can lead to serious health risks, such as bacterial infections, gastrointestinal illnesses, and even lead poisoning. Backflow prevention devices, such as backflow preventers, can help to prevent backflow and protect your family’s health.

How to Ensure Backflow Prevention in Your Home?

The best way to ensure backflow prevention in your home is to have a backflow preventer installed. A backflow preventer is a device that is installed in your home’s plumbing system to prevent backflow from occurring. There are several types of backflow preventers available, including:

Atmospheric Vacuum Breakers: These are the simplest and most affordable type of backflow preventers. They work by creating an air gap between the water supply and the potential source of contamination.

Pressure Vacuum Breakers: These backflow preventers are more complex than atmospheric vacuum breakers. They use a spring-loaded check valve to prevent backflow.

Double Check Valve Assemblies: These backflow preventers are the most reliable type of backflow preventers. They use two check valves to ensure that there is no backflow.

Backflow prevention is essential to ensure that your family has access to safe and clean water. By installing a backflow preventer in your home’s plumbing system, you can protect your family’s health and prevent the contamination of your water supply. At Cregger Plumbing, Heating, Cooling & Electrical, we offer backflow prevention services to help you keep your water supply safe and clean.

I had a basement drain backup and called several “emergency” plumbers that told me they couldn’t make it out at all today, or it would have to be well after regular hours at a grossly inflated price. Dominick from Cregger really came through for us. He arrived promptly (in about an hour), was professional, knowledgeable and quickly solved the issue. I’m grateful I didn’t have to rearrange my schedule last minute to deal with this. Thank you!

We called in the morning with a shower issue and they had a plumber out before noon. We were shocked they could do the job the same day. Josh did a great job converting our leaking three-handle shower to a new single handler. He also replaced the old galvanized pipes with copper.

Dominick was friendly, knowledgeable, and solved our plumbing issues quickly. This is the second time we’ve used Cregger and, while I hope we won’t have any other plumbing issues soon, Cregger will be our first call if we do.
