RATE
OF FLOW: Quantity of water
flowing past a designated point within
a specified time period, measured in
gallons per minute (gpm).
REAGENT: The chemical
indicators used in testing water balance. (All the little bottles
or tablets in your test kit).
RE-BAR: Reinforcement bar, used to add strength to a
concrete. After excavation of an in ground pool, a steel cage is
formed out of re-bar, and the gunite shell is shot over and surrounding
it.
RESIDUAL: Usually
refers to free available chlorine levels
remaining in the pool after initial treatment
or activity with contaminants.
RESTRICTED FLOW: The term used to describe a condition
preventing full flow of water. Restriction can occur with full skimmer
or strainer baskets, obstructions in the plumbing, dirty filter,
undersized plumbing or equipment , or placing devices like, heaters,
cleaners or fountains in the circulation system. Restriction on the
suction side creates higher vacuum, (or suction) while on the pressure
side creates higher pressure.
SAND
FILTER: A filter tank, usually
fiberglass or ABS plastic, filled with
sand and gravel. The pump diffuses water
over the top of the sand bed, and forces
it through the sand and into the laterals
on the bottom.
SANITIZER: A chemical agent used to remove unwanted
contaminants.
SCALE: Usually
whitish in color, scale forms
on pool surfaces and equipment when mineral salts are forced out
of solution. A scaling condition is one in which calcium hardness,
pH and/or alkalinity levels are out of balance.
SEQUESTERING AGENT: A
sequestering agent ties-up minerals tightly in solution, preventing
their precipitation, which colors the water and/or stains the pool.
Synonymous to chelators, these are commonly called stain & scale chemicals.
SKIMMER: A
surface skimmer is a plumbing fitting set at water level, containing
a weir mechanism and a debris basket. The skimmer is part of the
suction side circulation system.
SKIMMER
BASKET: Beneath the lid, the
basket strains debris, as the first line
of defense in filtering the water.
SKIMMER
NET: Attached to a telescopic
pole, a leaf rake is a very useful tool
in keeping the pool clean. Also called
a skimmer net are the flat, "dip
and flip"
nets, which aren't so useful.
SHOCK: As
a noun it loosely describes the products
used in shocking, such as hypochlorites,
potassium permonysulfate or hydrogen peroxide.
As a verb it describes the act of bringing
the sanitizer level up so high that breakpoint
chlorination is reached. When breakpoint
is reached, a "shock" or perhaps
a "lightning bolt" is a better
analogy, is sent through the water, tearing
apart molecules and slashing through cell
walls. Ultimate purification, man.
SHOTCRETE: A different type of application of the concrete
and sand mix which is used to "shoot the shell". Gunite
is pumped dry and mixed with water at the gun, whereas shotcrete
is pumped wet.
SNOWBELT: The
northern half of the United States where
freezing temperatures are particularly
common.
SODA
ASH: A base, used to counteract
an acidic condition by raising pH.
SODIUM
BICARBONATE (baking soda): Another
base, however its properties will increase
alkalinity more than pH. Used to raise
Total Alkalinity levels.
SODIUM
BISULFATE: An granular form
of acid, used to counteract a scaling
condition by lowering pH and/or alkalinity.
SODIUM
HYPOCHLORITE: Liquid chlorine
used in pools, identical yet stronger
than Clorox bleach.
SODIUM
TETRABORATE: New technology
that renders algae incapable of processing
carbon dioxide, which they need to
live.
SODIUM
DICHLOR: A granular form of
chlorine that is stabilized with cyanuric
acid. Used for shocking and super-chlorination.
SOFT
WATER: Water that has low calcium
and/or magnesium content. Soap lathers
easily in soft water.
SOLAR SYSTEM: Black mats of miniature plastic tubes
through which water is pumped, absorbing the heat as it passes through.
These mats are roof mounted with up & down plumbing connecting
it.
SOURCE: Refers to the origination of electrical power.
The source for your filter pump (load) is probably a timer clock.
SPA: A filtered, hot water vessel with hydrotherapy
jets and air induction. Can be portable or installed permanently.
Jacuzzi is a brand name. |
