Backflow Prevention Devices Help
Safeguard the Water Supply
When water flows backwards through the water supply system, it is
called backsiphonage or backflow. When that water is accidentally
mixed with hazardous chemicals or bacteria, it can be
dangerous...even fatal!
The danger could come from improperly installed pools and sprinkler
systems. In many districts, homeowners are required to have their
water district inspect a new pool or sprinkler system to help
prevent this problem. (Check with your district about specific rules
and regulations governing pools, spas, and irrigation systems.)
Another potential danger to the water system comes from a surprising
source. Did you know that a common garden hose could contaminate the
water supply if it is connected to a harmful substance and the
pressure in the water main line drops while your hose is submerged
in polluted or contaminated water? The water (and whatever is in it)
could be sucked back into your pipes and your drinking water supply.
Water pressure drops can happen when firefighters battle a nearby
blaze or when repairs are made due to a broken water line. This
contamination could come from the chemicals used to fertilize and
kill weeds on your lawn. The cleansers used in your kitchen and
bathroom could be hazardous if swallowed, as could bacteria in the
water from your pool or waterbed.
Fortunately, keeping your water safe from these contaminants is not
that difficult to do. Take the following precautions to protect your
drinking water:
- Buy and install inexpensive backflow prevention devices for all
threaded faucets around your home. They are usually available at
hardware stores and home improvement centers.
- If you install a pool or sprinkler system, have a representative
from your water district inspect the device for proper installation,
whether this is required or not.
- Never submerge hoses in buckets, pools, tubs or sinks.
- Always keep the end of the hose clear of possible contaminants.
- Do not use spray attachments without a backflow prevention device.
The chemicals used on your lawn are toxic and can be fatal if
ingested.
