Gaithersburg Backflow Prevention
Nearly Three Decades of Quality Service in Maryland
Backflow is the unintentional reversal of the flow of water through your plumbing system, which allows stale water to mix with the fresh drinking water supply. Backflow preventers are generally found on appliances such as boilers, radiators, and shower heads, and you can have backflow valves installed. Mallick Plumbing & Heating, Inc. provides backflow prevention in Gaithersburg and surrounding areas of Maryland.
If you have questions about backflow prevention and want to learn about the options, call (301) 804-6759 to speak with a knowledgeable member of our staff.
Causes of Backflow
While relatively uncommon, backflow occurs more often than most people think. Generally, it is caused by either an increase in pressure on the wastewater side of the plumbing system or a drop in pressure on the supply side, which is the most common.
The supply side pressure may drop suddenly due to:
- A broken water main
- Increased demand on the water supply as a result of firefighting efforts
- A widespread power outage
- Plumbing work requiring draining the entire house
- New equipment causing a significant pressure change
Regardless of the cause, the last thing you want is wastewater in the drinking water supply. The places where backflow is most likely to occur include plumbing fixtures such as handheld shower heads, appliances such as boilers and radiators, and lawn irrigation systems. The water from these appliances can flow backward due to pressure changes.
