Backflow Prevention

Not everyone is aware of the importance of a backflow prevention solution in a residential plumbing system. They are an important part of the system because they prevent adverse health effects that can be caused by wastewater going the wrong direction and entering the “fresh” water supply.

Backflow is the reverse flow of contaminants into your potable water supply. Essentially, backflow prevention solutions safeguard drinking water from becoming contaminated by backflow. Old World Plumbing offers backflow prevention services to keep our clients safe and clean water flowing in the right direction.

While most public water supply systems offer enough pressure to keep water flowing to faucets, showerheads and other water-using appliances, that pressure can be compromised during times of high demand or if a water main fails. It’s during these moments that wastewater can be drawn into the system from leaking sewage, soil or storage tanks and other sources, creating a health risk.

The actual backflow prevention device provides an air gap in an open vertical space between devices that are part of a plumbing system. This could be a valve or a faucet or any part of the system where contaminated water could find its way in.

What is an RPZ backflow preventer device and why do you need it tested?

RPZ stands for reduced pressure zone, which are assembly valves that protect water supplies from being contaminated. Generally speaking, these are devices put in place to prevent drinking water and the municipal water supply from being contaminated.

The way they work is that when the normal pressure that feeds water to a home is reduced, the RPZ kicks in to prevent any backflow from occurring. For example, let’s say you have a water leak in the house or the municipal water supply fails for one reason or another – that reduced pressure can cause contaminates from irrigation systems, which might contain toxic pesticides or fertilizers, to back up into the drinking water supply. The RPZ is there to stop that from occurring.

To ensure that the RPZ is in working order and will perform as advertised in times of need, it should be inspected and tested. Illinois law mandates that a plumber who is licensed with Cross-Connection Certification carry out the backflow preventer inspections on the RPZ device every year. If your RPZ device passes, the plumber will fill out the necessary paperwork and pass it on to your municipality. If it does not pass inspection, the plumber should have the necessary skills to repair or replace the RPZ device.
