Home Safety Council® Research Reveals The Majority of Families Overlook Drowning Dangers at Home

National Nonprofit’s New Interactive Tool Will Help Families Stay Safer In and Around the Pool This Summer

Home Safety Council research shows that drowning is one of the leading causes of unintentional injury-related death across all age groups, yet a recent study commissioned by the national, nonprofit organization found that only six percent of respondents have taken any action to prevent drowning incidents at home. Of those polled, fewer than 10 percent have put in a four-sided fence that goes all around the pool or installed a gate that closes and locks by itself – two of the key water safety tips recommended by the Home Safety Council.

As the temperatures rise and families begin to spend their time in and around the pool, the Home Safety Council is working to make parents and caregivers aware of water-related dangers and encouraging them to take an active role in protecting their children from those risks.

“No one should swim alone. Close, active adult supervision is particularly vital when children are around water,” said Meri-K Appy, president of the Home Safety Council. “Drowning can occur in just seconds without noise or sign of struggle, so adults need to stay within arm’s reach and remain entirely focused on children when they are around any body of water.”

In addition to drowning, pools and spas also introduce the risk of injuries from falls, poisoning, scalds, entrapment and electric shock. The Home Safety Council’s new, online destination, MySafeHome.org (link to http://www.mysafehome.org/), lets users explore all the areas of a virtual home to understand where potential dangers may be found in their own homes. MySafeHome.org includes an interactive pool and spa area that illustrates the most common injury risks found around backyard pools and spas and demonstrates the safety devices and practices needed to reduce the risk of injury.

Water Safety Tips:

The Home Safety Council offers the following water safety tips for activity in and around pools, spas, ponds and irrigation ditches, bathtubs and buckets.

  • Install four-sided fencing with self-locking and self-closing gates around pools and spas. Fencing should completely isolate the pool from the home and be at least five feet high.
  • Always keep gates closed and latched. Never prop a gate open or disable the lock.
  • Always practice constant adult supervision around any body of water, including pools and spas. Never leave your child alone or in the care of another child.
  • When hosting a pool party, assign specific adults to keep an eye on the pool at all times.
  • Enroll non-swimmers in swimming lessons taught by a qualified instructor.
  • Remember that regardless of age or skill level, no one is “drown proof.” Children should always be supervised by an adult while they are swimming.
  • Never swim alone. Even adults should swim with a buddy.
  • Learn and practice basic lifesaving techniques, including First Aid and CPR. Insist that anyone who cares for your children learn CPR.
  • Keep poolside rescue equipment close to the pool area at all times, and bring a cordless telephone outside while using the pool.
  • Post emergency numbers and CPR instructions near the pool area.
  • Entrapment underwater can be deadly. Teach children that drains, grates and filters are not toys. Never stick fingers or toes in these openings and stay away from suction devices.
  • Install anti-entrapment drain covers and replace drain covers immediately if they are broken or damaged.
  • Always remove toys from the pool area when not in use.
  • Establish pool safety rules and make sure children are familiar with them.
  • Keep spas and hot tubs covered and locked when not in use.
  • Completely remove pool and spa covers prior to use.
  • Stay out of the pool during severe weather and thunderstorms, especially if lightning is forecast or present.
  • If a child is missing, check the pool area first.

Calculate your swimming pool water loss in gallons per hour

Tuesday, September 22nd, 2009

When you suspect your pool is leaking and you want to know how many gallons of water it is losing, by using data from a bucket test and the dimensions of your pool, you can figure out how many gallons per hour or minute your pool is losing.

Use the swimming pool water loss calculator.

Calculation examples:

Example #1:

A pool owner says his 18×27 pool is losing 2 inches per day. How many gallons is the pool losing per day?
The formula is: L (x) W (x) WL (x) .6233 = Gallons Lost

The given values are: L = 32′  W=18′   WL=2″

Plugging the values into the formula we have:
32 (x) 18 (x) 2 (x) .6233 = 718.04 gallons

The 718 Gallons lost also gives you an idea of how big the leak is that you are looking for.  The example also means that they are losing:

  • 29.9 gallons per hour! (718 divided by 24) and …
  • 0.498 gallons per minute! (29.9 divided by 60)

That’s two quarts per minute!  What size stream of water would it take to fill a quart container in one minute?  About the diameter of a pencil.

Example #2:

A spa owner says he has to add 1.5 inches of water daily to his 12′ diameter spa. How many gallons of water is the pool losing?  The formula for round pools and spas is:
Diameter (feet) (x) Diameter (x) WL (x) .48929 = Gallons Lost

The given values are: Diameter= 12 feet   WL=  1.5 inches

So, plugging the values into the formula, we have:
12 (x) 12 (x) 1.5 (x) .48929 = 105.69 Gallons lost in 24 hours

Use the swimming pool water loss calculator at americanleakdetection.com to find out how many gallons per hour your pool is losing due to leakage.

Top 10 In-Ground Swimming Pool Issues

Tuesday, August 18th, 2009

There are many issues that in-ground swimming pool owners can experience during the life of their pool. Below is our top ten:

10: Water table

The level of the water table in the ground can affect your pool’s construction and how it will respond to changing climatic conditions. If the ground water table is high, your pool can be subject to “floating” in the ground. Keeping the water level in the pool stable helps combat the pool from floating up.

In most areas, pools will have a hydrostatic valve installed to help proper equalization of the water table with the pool water level.

If a leak occurs and the ground water table is low, then a leak will be quickly absorbed by the surrounding ground, and possibly wash away the dirt from around the leakage point causing voids around the pool structure.

Gunite Swimming Pool Repair Explained

Thursday, July 23rd, 2009

What is gunite?

Gunite is a mixture of cement, sand, and water that is sprayed on a surface under pneumatic pressure.

Gunite, along with a rebar frame, is used to create the structure of the pool. Plaster is then applied to create a water barrier. Gunite is porous and should not be used by itself to construct a pool. There must be a water barrier between the porous gunite and the water. If the plaster is not thick enough, it could allow water to seep through the gunite. This will result in water loss that is difficult to isolate without draining the pool. There are methods for repairing a pool that is not properly sealed with enough plaster.

What is causing a consistent flow of bubbles from the return pipe to the swimming pool?

Friday, June 12th, 2009

We receive a lot of phone calls asking the same question. In most cases, a pool or spa owner has checked all of his or her pool equipment and even had a pool service technician do the same. Even after tightening every visible screw and lubricating all of the obvious seals, the bubbles continue to flow through the return lines. So what might be happening?

In most cases, air is getting into the system at some point that just might not be discernible to most homeowners or even pool service men. For example, there may be a leak on an underground suction line. As the pump draws water from the pool through this line, it also draws air through the leak. Without x-ray vision, homeowners and most pool service companies cannot detect this kind of leak. It takes specialized testing with modern leak detection equipment, something a good leak detection company can perform.

Besides underground leaks that allow air intrusion into the system, there may even be leaks on above ground equipment that cannot be detected without modern leak detection methods.

There is one other possibility that is not leak related. Sometimes the impeller inside the pump becomes so worn that it actually spins too fast. As a result, the impeller can end up spinning fast enough to break apart water molecules and form air bubbles to be sent through the return lines.
