Backflow Services

The plumbing pipes that lead from your drain to the sewer line are only supposed to flow in one direction — away from your house. However, plumbing damage, flooding, or heavy rains can sometimes cause water to flow back up your sewer line and into your home.

The resulting sewage backup is unpleasant, but fortunately, there is a solution — backflow preventers. These devices seal off your pipes, preventing water from forcing its way back through. The team at Roto-Rooter Plumbing & Water Cleanup of St. George and Cedar City is here to discuss more about these devices and our backflow installation services in St. George & Cedar City!

Backflow Service

There are several different types of backflow irrigation mechanisms, but all of them work by keeping the water supply from reversing direction:

  • Air gaps work by creating a gap of air between the hose running dirty water and the drain. Separating the two hoses ensures dirty water doesn’t contaminate drinking water.
  • Check valves typically have a flap or some other physical mechanism that shuts off the pipe when water starts flowing opposite the intended direction.
  • Vacuum breakers open special air vents when the system loses pressure and seal off the water supply line.

Basically, backflow devices keep drinking water from becoming contaminated with dirty water and keep dirty water out of your property.

Below are some common questions we receive about our backflow services.

Are Backflow Devices Necessary?

What Causes Backflow?

Backflow can result from many things, most often flooding and heavy rains. The excessive water increases the pressure in municipal sewers, causing an undesirable reversal of wastewater back up into your plumbing system.
