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): T

his 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.
