STABILIZER: See Cyanuric Acid. Stabilizers, also called conditioners, can be added directly to your pool to extend your chlorine efficacy. This will help prevent your chlorine from disappearing on a particularly sunny day. They slow down the chlorine reaction in your pool water and reduce the conversion rate of chlorine. Cyanuric acid is already added to certain "stabilized" products such as Trichlor tablets and Sodium Dichlor.
STANDPIPE: This is a vertical pipe that's purpose is to carry water the lateral assembly and hub to or from the multiport valve on a top mount sand filter system.
STRAINER BASKET: A basket for your pool pump that has smaller holes than those found in a skimmer basket and help prevent the pump impeller from clogging.
STRATOSPHERE: This is the second layer of the Earth's atmosphere, which is directly above the troposphere and just below the mesophere. The warmer layers are at the top of the stratosphere and the cooler temperatures further down.
SUCTION SIDE: The side of the pool pump which is under vacuum pressure. This is the plumbing that carries water to the pump.
SUNBELT: The southern portion of the United States where cold weather is very rare and typically having very high temperatures.
SUPER-CHLORINATION: When you apply seven to ten times the usual amount of chlorine to the pool water to assist in contaminant removal. This is sometimes referred to as "shocking" the pool but is actually slightly less than the amount of chlorine used to normally shock a swimming pool.
TDS: See Total
Dissolved Solids
TEE: Plumbing fitting which is used to combine two separate pipes into one.
TEST
KIT: One of the methods used to test the water balance and chemical levels of swimming pool water.
TIME CLOCK: A clock which controls the timing operation of pool equipment such as your pool filter and booster pumps. Used to automate different processing for your swimming pool systems.
TITRATION: Used for testing of total alkalinity, calcium hardness and acid/base demand by adding a titrant. A single drop of this substance is added to the water until a change can be observed.
TOTAL
ALKALINITY: This is the ability of pool water to fight change in pH levels. Also known as the "buffering" capability of the swimming pool water. Adding Sodium BiCarbonate will increase alkalinity levels, expressed in ppm.
TOTAL DISSOLVED SOLIDS (TDS): This is a measure of anything that has ever dissolved in a certain body of water, all matter that is in the solution. High Total Dissolved Solids (TDS) can leave your water over-saturated which can lead to any number of chemical reactions in the water.
TRICHLORO-S-TRIAZINETRIONE: A white crystalline powder commonly used as an industrial disinfectant, bleaching agent, and a reagent in organic synthesis. It features a strong "chlorine odor" and can be sold in tablet or granular form for both home and industrial uses.
TROWEL: A flat-blade tool with rounded ends that is used to apply viscous or particulate coatings to concrete. Most commonly used on pool decks.
TURBIDITY: This is one of the key tests of water quality. It is the cloudiness or haziness in pool water caused by individual particles (suspended solids) that are usually invisible to the naked eye.
TURNOVER: How long it takes for your swimming pool pump to send all the water in your pool through the filter and back. The most common turnover amount of time for swimming pools is eight hours.
ULTRA VIOLET LIGHT: A frequency of light that is invisible to humans that is emitted by the sun and special lamps. It can cause chemical reactions and causes many different substances to glow (used in black lights).
ULTRA VIOLET LIGHT TREATMENT: Harnessing special UV Light radiation to destroy water contaminants. It is also used to create ozone molecules for the same outcome.
UNDERDRAIN: The lower portion of the collection system in a swimming pool filter - used to direct previously filtered water back into the swimming pool. During backwash treatments it pushes the water in reverse.
VACUUM: The cleaning process for a swimming pool that includes sucking leaves, algae, and other debris from the pool floor. This done by creating a low pressure condition in the suction line.
VALVES: Restricts or obstructs water flow for adjusting hydraulics. Can also be used to only allow water flow in one direction, like a check valve. This device is placed in the plumbing line.
VERMICULITE: This is a special mineral that expands greatly when heat is applied to it. This is an effect that is commonly produced in commercial furnaces.
VENTURI: A method of increasing water velocity in a spa by restricting pipe size. |
