Backflow Prevention

Backflow Prevention

by Nick Gromicko and Kenton Shepard
Backflow is the reversal of the normal and intended direction of water flow in a water system. Devices and assemblies known as backflow preventers are installed to prevent backflow, which can contaminate potable water supplies.
 
Why is backflow a problem?

Backflow is a potential problem in a water system because it can spread contaminated water back through a distribution system. For example, backflow at uncontrolled cross connections (cross-connections are any actual or potential connection between the public water supply and a source of contamination or pollution) can allow pollutants or contaminants to enter the potable water system. Sickness can result from ingesting water that has been contaminated due to backflow.

Backflow may occur under the following two conditions:

back-pressure:
Back-pressure is the reverse from normal flow direction within a piping system as the result of the downstream pressure being higher than the supply pressure. This reduction in supply pressure occurs whenever the amount of water being used exceeds the amount of water being supplied (such as during water-line flushing, fire-fighting, or breaks in water mains).

back-siphonage:

Back-siphonage is the reverse from normal flow direction within a piping system that is caused by negative pressure in the supply piping (i.e., the reversal of normal flow in a system caused by a vacuum or partial vacuum within the water supply piping). Back-siphonage can occur when there is a high velocity in a pipe line, when there is a line repair or break that is lower than a service point, or when there is lowered main pressure due to high-water withdrawal rate (such as during fire-fighting or water-main flushing).
Atmospheric Vacuum Breakers

Backflow prevention for residences is most commonly accomplished through the use of atmospheric vacuum breakers (AVBs). AVBs operate by allowing the entry of air into a pipe so that a siphon cannot form. AVBs are bent at 90 degrees and are usually composed of brass. Compared with backflow preventer assembles, AVBs are small, simple and inexpensive devices that require little maintenance or testing. They have long life spans and are suitable for residential purposes such as sprinkler systems. InterNACHI inspectors can check for the following:

  • The AVB must be at least 6 inches above any higher point downstream of the device. For this reason, they can never be installed below grade. Even if they are installed 6 inches above grade, inspectors should make sure that they are not installed less than 6 inches above some other point in the system downstream of the device.
  • The AVB cannot be installed in an enclosure containing air contaminants. If contaminated air enters the water piping, it can poison the potable water supply.
  • A shut-off valve should never be placed downstream of any AVB, as this would result in continuous pressure on the AVB.
  • AVBs cannot be subject to continuous pressure for 12 hours in any 24-hour period or they may malfunction.
  • Spillage of water from the top of the AVB is an indication that the device has failed and needs to be replaced.

 

Types of Backflow Preventer Assemblies

Some types of assemblies are common in commercial and agricultural applications but are rare for residential uses. The appropriate type of backflow preventer for any given application will depend on the degree of potential hazard. The primary types of backflow preventers appropriate for use at municipalities and utilities are:

  • double check valves:  These are commonly used in elevated tanks and non-toxic boilers. Double check-valve assemblies are effective against backflow caused by back-pressure and back-siphonage and are used to protect the potable water system from low-hazard substances. Double-checks consist of two positive-seating check valves installed as a unit between two tightly closing shut-off valves, and are fitted with testcocks.
  • reduced pressure principle assemblies:  These are commonly used in industrial plants, hospitals, morgues, chemical plants, irrigation systems, boilers, and fire sprinkler systems. Reduced pressure principle assemblies (RPs) protect against back-pressure and back-siphonage of pollutants and contaminants. The assembly is comprised of two internally loaded, independently operating check valves with a mechanically independent, hydraulically dependent relief valve between them.
  • pressure vacuum breakers:  These are commonly used in industrial plants, cooling towers, laboratories, laundries, swimming pools, lawn sprinkler systems, and fire sprinkler systems. Pressure vacuum breakers use a check valve designed to close with the aid of a spring when water flow stops. Its air-inlet valve opens when the internal pressure is one psi above atmospheric pressure, preventing non-potable water from being siphoned back into the potable system. The assembly includes resilient, seated shut-off valves and testcocks.
Requirements for Testers and Inspectors

A number of organizations, such as the American Water Works Association (AWWA) and the American Backflow Prevention Association (ABPA) offer certification courses designed to train professionals to test backflow preventers. Requirements for training vary by jurisdiction. Inspection of backflow preventers requires knowledge of installation requirements, although inspectors are not required to become certified.
In summary, backflow preventers are designed to prevent the reverse flow of water in a potable water system. They come in a number of different types, each of which is suited for different purposes.

Round Rock Home Inspector Discusses How To Save On Energy

Ways to Help Beat The Heat This Summer

As the summer has quickly over taken us and the temperatures already in the mid 100 degree range in Williamson County Texas. We are all looking for ways to help lower our energy costs.

As a licensed home inspector for over twenty years, I always look for ideas and ways to lower monthly bills to help keep the energy bills affordable. I found this information by the U.S. Department of Energy and thought I would pass this along.

The U.S. Department of Energy provided some easy, low-cost and no-cost ways to help save energy this summer:

  • Install a programmable thermostat to lower utility bills and manage your heating and cooling systems efficiently.
  • Air dry dishes instead of using your dishwasher’s drying cycle.
  • Turn things off when you are not in the room such as lights, TVs, entertainment systems and your computer.
  • Plug home electronics, such as TVs and DVD players, into power strips; turn the power strips off when the equipment is not in use—TVs and DVDs in standby mode still use several watts of power.
  • Lower the thermostat on your water heater to 120°F.
  • Take short showers instead of baths and use low-flow showerheads for additional energy savings.
  • Wash only full loads of dishes and clothes.
  • Air dry clothes.
  • Check to see that windows and doors are closed when heating or cooling your home.
  • Drive sensibly; aggressive driving such as speeding, and rapid acceleration and braking, wastes fuel.
  • Look for the ENERGY STAR® label on light bulbs, home appliances, electronics, and other products. ENERGY STAR products meet strict efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy.

These are all good ways to help beat the heat this summer. If I may as a home inspector I would like to offer other way to keep things cool.

That is by changing out you’re a/c filter. Keeping the filter clean will maximize the air flow to your HVAC system and help with the efficiency of the unit.

Keep all bushes and items away from the outside compressor unit at least 2 feet and above by 6 feet, this will keep the air flowing around the unit to cool the coils. Air flow is most important to help keep your utility bills low.

Round Rock Home Inspector Discusses Home Safety With GFCI’s

Home Safety and GFCI Protected Outlets

As a licensed professional home inspector, I test electrical outlets every day during home inspections. Ground fault circuit interrupters or GFCI is an inexpensive electrical device that can either be installed in your electrical system or built into a power cord.

 

These devices are used to protect you from severe electrical shocks, burns and injuries by detecting ground faults.

GFCI Outlet

 

A ground fault is an unintentional electrical path between a power source and a

grounded surface.  Ground faults most often occur when equipment is damaged

or defective, such that live electrical parts are no longer adequately protected

from unintended contact. If your body provides a path to the ground for this

current, you could be burned, severely shocked or electrocuted.

 

Areas that GFCI protection should be in or around all wet areas such as:

Pools, hot tubs, and receptacles that are located:

  • Outdoors
  • Bathrooms
  • Garages
  • Kitchens and island cabinets
  • Wet bars
  • Laundry rooms/utility sinks
  • Crawl spaces/basements

 

Consider using a GFCI protected cord if you are using power equipment outdoors.

 

GFCI receptacles should be tested often. It takes no special equipment or device to test, just simply push the test button. It should trip, and then push the reset button to power up the outlet. If it does not trip you should have the receptacle replaced.

 

Many home injuries can be avoided each year by using and testing these devices.

Round Rock Home Inspector Discovers Dirty Coil

http://www.roundrockhomeinspector.com Round Rock Home Inspector discovers this dirty a/c coil during a home inspection. A dirty a/c coil can reduce the efficiency of the unit and it can cost you money everyday even during the heating cycle. The obstruction on the coil restricts the air flow going back through the unit.

Keeping a clean filter will keep the coil from becoming dirty and by using a higher quality filter will add life and lower utility bills in the future. I recommend using a filter made by AFM Filters, they are made right here in Texas. The link to order the filter is http://afmfilters.com/CharlesSchiller.
