STABILIZER:  See Cyanuric Acid. Stabilizers, also called conditioners, can be added directly to your pool to extend your chlorine efficacy. Cyanuric acid is already added to certain "stabilized" products such as Trichlor tablets and Sodium Dichlor.

STANDPIPE: Vertical pipe that carries water from the hub and lateral assembly to or from the multiport valve on a top mount sand filter.

 

STRAINER BASKET:  The second line of defense is a basket at the pump. The holes in this are smaller than those in a skimmer basket, and prevent the pump impeller from clogging up.

 

STRATOSPHERE: The second layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. It is stratified in temperature, with warmer layers higher up and cooler layers farther down. This is in contrast to the troposphere near the Earth's surface, which is cooler higher up and warmer farther down

SUCTION SIDE:  The plumbing prior to and carrying water to the pump. This side is under vacuum pressure.

 

SUNBELT: The southern half of the United States where freezing temperatures rarely occur, and high temperatures are particularly common.

 

SUPER-CHLORINATION:  Applying 7 - 10 times the normal amounts of chlorine to the pool as an added "boost" for contaminant removal. Some refer to super-chlorinating as being less than shocking, in that breakpoint thresholds are not reached, or the terms may be used synonymously. 

 


 

TDS: See Total Dissolved Solids

 

TEE:  A plumbing fitting used to bring two pipes together into one, or vice-versa.

TEST KITA method used to test the water balance and sanitizing level of your pool water.

TIME CLOCK:  A mechanical device that controls the timed operation of your electrical equipment, primarily your filter and booster pumps.

 

TITRATION:  A method of testing for total alkalinity, calcium hardness and acid/base demand by adding a titrant, drop by drop until a color change is observed.

 

TOTAL ALKALINITYThe ability of the pool water to resist changes in pH. The "buffering" capacity of the water. Additions of Sodium Bicarbonate will increase the levels, expressed in ppm.

 

TOTAL DISSOLVED SOLIDS (TDS):  A measure of everything that has ever dissolved in the water; all the matter that is in solution. High TDS levels can oversaturated your water, causing all sorts of reactions.

 

TRICHLORO-S-TRIAZINETRIONE: a chemical compound used as an industrial disinfectant, bleaching agent and a reagent in organic synthesis. This white crystalline powder, which has a strong "chlorine odour," is sometimes sold in tablet or granule form for domestic and industrial use.

 

 

TROWEL: A pool trowel is a flat-bladed tool with rounded ends used to apply viscous or particulate material coatings to concrete, especially on pool decks.

 

TURBIDITY:  Cloudy, dull, hazy water, due to micro particle suspension.

TURNOVER:  The amount of time it takes your pump to move all the water in your pool through the filter and back again. Usually, pools are designed for an eight hour turnover.



ULTRA VIOLET LIGHT: Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It is so named because the spectrum starts with wavelengths slightly shorter than the wavelengths humans identify as the color violet (purple).

 

ULTRA VIOLET LIGHT TREATMENT:  Using UV wavelength radiation to destroy contaminants in water. UV light is also used to create ozone molecules for the same purpose.

UNDERDRAIN:  The lower collection system in a filter which directs filtered water back towards the pool. It also distributes water in reverse during backwashing. See laterals.



VACUUM:  Refers to the low pressure condition created in the suction line. Also refers to the cleaning process of sucking leaves, algae and debris from the pool floor.

VALVES:  A device placed in the plumbing line which restricts or obstructs water flow to create desired hydraulics, or may permit flow in one direction only (as in a check valve).

Vermiculite: A natural mineral that expands with the application of heat. The expansion process is called exfoliation and it is routinely accomplished in purpose-designed items. Vermiculite is formed by hydration of certain basaltic minerals.

 

VENTURI:  Increasing water velocity by restricting pipe size usually accomplished by a spa jet.
