Sec. 19.
(a) "Total discharge head" means the value in feet (meters) of water that a pump will raise water above its center line.
(b) "Total dynamic head" or "TDH" means the arithmetical difference between the total discharge head and total suction head (a vacuum reading is considered as a negative pressure). This value is used to develop the published performance curve.
(c) "Total dynamic suction lift" or "TDSL" means the arithmetical total of static suction lift, friction head loss, and velocity head loss working on the suction side of the pump.
(d) "Total suction head" means the value in feet (meters) of water that a pump will lift by suction.
(e) "Toxic" means having an adverse physiological effect on man.
(f) "Trap" means a fitting or device so designed and constructed as to provide, when properly vented, a liquid seal that will prevent the back passage of air without materially affecting the flow of sewage or wastewater through it.
(g) "Trimmer valve" means a flow adjusting device that is used to proportion flow over the skimming weir and flow through the main suction line from the main outlet or the vacuum cleaning line.
(h) "Turnover time" means the period of time required to circulate a volume of water equal to the pool capacity.
