Total Alkalinity
|
(TA) A measurement of the ability of the water to resist changes in pH. Water with a TA of 80-120 PPM is sufficiently buffered, so as to resist rapid changes in pH. This makes pH management easier. Additions of sodium bicarbonate are used to raise the total alkalinity: 1.5 pounds will raise the TA of 10,000 gallons by about 10 PPM. High TA can be lowered by the addition of dry acid (sodium bisulfate).

T-handle Sliding Valve
|
A plumbing device used to stop water flow in order to perform maintenance. T-handle sliding valves keep the spa water in the spa while allowing you to change out other parts such as heaters and pumps.

Temperature Probe
|
The electrical component that measures water temperature.
|
|
Topside Control
|
The user-interface panel that connects to the control box and controls various spa functions such as jet pumps and heater.
|
|
Total Dissolved Solids
|
(TDS) A measurement of the total PPM of all dissolved minerals and compounds. High TDS can lead to water clarity problems, loss of sanitizer effectiveness and other issues.
|
|
Ultraviolet
|
(UV) A form of light energy used in spa sanitizers used to reduce the overall population micro-organisms. Because UV rays from the Sun can destroy bromine, cyanuric acid conditioner/stabilizer is used to minimize the negative effect of sunlight on the bromine concentration.

Union
|
A plumbing device that quickly allow connection or disconnection of a pipe.

|
Water Chemistry
|
In order to minimize the possibility of spa water problems and to maximize the bathing pleasure, it is important to maintain or balance common water parameters. These parameters include: sanitizer level, pH, total alkalinity, calcium hardness, and the control phosphates, nitrates, and trace heavy metals.

|
Water Mold
|
A catch-all phrase that describes the problem of a bacterial or microorganism bloom that can cover broad areas and can cloud the water. Can be pink or white in appearance. Sometimes, present in a form that is describing as resembling "floating, shredded toilet tissue." It is usually caused by the development of a resistant strain and is more common in pools or spas that have been maintained on biguanide for long periods of time.
|
|
Water Quality
|
Refers to the state of the overall spa water conditions, regarding such factors as: sanitation, water chemistry, water clarity, water color, and the appearance of the underwater surfaces. Water quality can become an issue in a variety of spa problems that detract from the goal of sparkling crystal clear water.

|
Weir Door
|
The pivoting door between the filter area and the spa water. When the water level is proper (within 1/4" of the top of the vertical door), this door automatically flops into the filter area when the pump turns on and returns to vertical (upright) when the pump turns off.

Winterizing
|
A series of steps taken in order to protect the equipment and prepare the spa for the inactive winter period.
