Backflow Prevention in Silver Spring, MD & Montgomery County

A basic but important part of residential plumbing is backflow prevention. Backflow is the accidental reverse flow of water through the plumbing. This may not sound like it’s a serious problem, but when backflow happens in residential plumbing, stale water can mingle with the freshwater drinking supply—and that’s not something you want to happen!

Your home should have a number of backflow preventers attached to appliances that might allow backflow. These include handheld showerheads, boilers, radiators, and especially irrigation systems. Count on the professional plumbers at Mallick Plumbing & Heating to take care of your residential backflow preventer needs. We can install backflow valves on the household fixtures that need them so your family’s health is protected. Simply give us a call to schedule a plumber in Silver Spring, MD and the surrounding Montgomery County area.

We are the Service Contractor of Choice!

What Causes Backflow?

Backflow isn’t common, but it still occurs more often than people think. What causes it is either an increase in pressure on the wastewater side or a drop in pressure on the supply side. The second scenario is more frequent, and there are a number of reasons for it to happen:

  • A broken water main
  • Work on a home’s plumbing that requires draining down the entire house
  • A widespread power outage
  • Firefighters placing a large demand on the local water supply to put out a fire
  • A new piece of water–using equipment that causes a large pressure change

Backflow Prevention

Regardless of the cause, the outcome is similar: non–potable (i.e. water you can’t drink) moves the wrong direction through the home’s plumbing. The places in a house where backflow can occur are hand–held shower heads, lawn irrigation (such as sprinklers), radiators, and boilers. Water from any of these appliances can potentially flow backward in the plumbing because of pressure changes. This places stale water from the common residential system in the fresh drinking water. One of the major areas of concern where a house needs backflow prevention devices installed is on irrigation systems, such as sprinklers and hose bibs.

When a backflow prevention device detects a change in pressure in the plumbing, a check valve shuts to stop water from flowing in the wrong direction. The check valve isn’t the only type of backflow preventer available. If you’re a homeowner and are unsure if you need to have backflow prevention or which backflow preventers will do the job, call on our certified plumbers for assistance.
