What is Water Backflow?

Contaminating the water supply can cause death.

In the same manner as sucking a drink through a straw, contaminants can enter your drinking water line from “cross connections”.

A water cross connection is where a non-drinking water substance (sometimes deadly) has the ability to come in contact with drinking water. Water cross connections such as these can easily enable contaminants to enter the water lines through a process known as backflow.

Backflow is:

• Water flowing in the opposite direction of its normal flow and caused by a drop in pressure in a water system (opening a fire hydrant?).
• Undesirable reversal of flow of non-drinking water substance through a cross connection and into the piping of a public water system.
• Can allow bacteria, chemicals or physical contaminants to enter the water system and contaminate the water supply of not only at the contamination site but also for those who might drink water from water sources down the line from the contamination site.

Sewer Backflow Valve Can Prevent A Big Mess.

Protect your property from flooding, especially sewage:

In some flood-prone areas, flooding can cause sewage from sanitary sewer lines to back up into homes or businesses through drain pipes. These backups not only cause damage that is difficult to repair but also create health hazards.

A good way to protect your building from sewage backups is to have PDM Plumbing install sewer backflow valves, which are designed to block drain pipes temporarily and prevent flow into your house or business.

Sewer backflow valves are available in a variety of designs that range from the simple to the complex. Call PDM for free help.
