The Virginia Graeme Baker Pool & Spa Safety Act of 2007—Summary
This new federal law was enacted to help prevent suction entrapment
injuries and becomes effective December 19, 2008. The requirements for
public swimming pools, spas, and wading pools are summarized below
and must be met before these facilities can be operated after that date.
Drain Cover Requirements - New drain covers certified to ASME/ANSI
A112.19.8–2007 must be installed.
Backup System Requirements - Suction piping for each pump must be
inspected and will be considered in compliance with the federal law if:
1) no submerged drains connect to the pump, or 2) there are two drains
at least 3 feet apart, or 3) there is a single “unblockable” drain. An
unblockable drain includes a sump under the cover that is larger than 18
inches by 23 inches, or a channel type drain with a diagonal open area of
at least 29 inches.
Single-and two-drain systems less than 3 feet apart that fail to
meet one of the above requirements must be updated by adding,
1) Safety Vacuum Release System (SVRS), 2) Suction-Limiting Vent
System, 3) Gravity Drainage System, 4) Automatic Pump Shut-Off
System, 5) Drain Disablement, or 6) Other Systems determined by
Consumer Product Safety Commission to be equally effective.
Another option is to split the single drain into a dual-drain system
with at least 3 feet of separation.

and Spa Safety Act and how to comply, review the U.S.

Two key technology innovations drive
significant energy savings
IntelliFlo VS
+
SVRS pump includes exclusive, breakthrough motor
technology and controllable, variable-speed technology that
combine to drive down energy use and cost. And the savings
potential may be measured in thousands of dollars over its
long life.
First, the IntelliFlo
VS+SVRS pump uses an exclusive permanent
magnet motor—like those used in hybrid cars—in place of a
traditional induction motor. Permanent magnet motors are
fundamentally more energy efficient.
Second, the IntelliFlo VS
+
SVRS pump includes a variable speed
capability, along with digital controls and proprietary software
that allow custom programming of optimum pump speeds for
specific tasks—filtering, heating, cleaning, spa jets, etc.
Traditional pumps’ one pre-set speed are almost always greater
than that needed to meet the health department turnover
requirements.
With a variable speed pump, the optimum speed will almost
always be lower than the pre-set, unchangeable speeds of older
pumps. IntelliFlo
VS+SVRS pump’s eight settable, changeable
speeds (ranging from 1100 to 3450 RPMs) mean you can program
the exact flow requirements for each task, assuring the lowest
energy use possible…adding to your savings. Plus with IntelliFlo
VS+SVRS pump, you may be able to further reduce energy costs by
reducing flow rates during non-pool use hours while maintaining
24 hour-a-day filtration…at a much lower cost. Check with your
local health department for requirements in your area.
Here’s just one comparative example:
Pump Annual Kilowatts Use Annual Electric Cost Savings Difference*
@ 24 hr/day Run Time @.15 Kwh
2 HP 19,272 $2,891

Actual savings can vary. Example reflects savings for an average 30,000 gallon commercial pool operating 24 hours per day
at a flow rate sufficient to perform a minimum 6 hour turnover.

Pump Motor Speed vs. Power Consumption
100
Why slower is better
The surprising secret to minimizing pump energy costs is to
operate at the lowest speed needed to accomplish a job. It takes
far less energy to move water slowly than quickly. Why? Because
there’s lower resistance in the filter, accessories and plumbing
system. Even with only modest pump speed reductions, the effect
on electricity usage can be dramatic. In fact, reducing pump motor
speed by 25% actually reduces the power needed by 58% of
what’s consumed at the higher speed. A good analogy is your car:
you get much better gas mileage at 30 mph than at 90 mph. The
same is true with pool pumps—run slower to reduce energy used.

Engineered for exceptionally long life
IntelliFlo VS
+
SVRS pump’s permanent magnet motor produces far
less heat and vibration than traditional induction motors. This not
only results in less stress and wear on pump components, but on
other equipment, too. Exclusive load-sensing software provides
nearly instant priming which saves energy and reduces wear and
tear on the pump. Plus, built-in diagnostics protect the IntelliFlo
pump from the most common causes of premature pump failure—
overheating, freezing, and voltage irregularities. The result is you
can expect dramatically longer life and an even greater return on
your investment.
Other valuable features
IntelliFlo VS
challenges:
• Easy to program and monitor: simple push-button controls and
clear LCD readouts show status and text alerts to make
operation a cinch.
• Ability to set minimum and maximum speeds: IntelliFlo will only
operate within the ranges you set to help assure safe operation
and long equipment life.
• Built-in clock and timer: Obsoletes the need for an added time
clock or expensive controller.
