But if the leak is causing the pump to cycle on and off too frequently then the leak should be fixed. The built-in pressure tank will usually be sufficient for a minor leak. Pumps last longer by having longer running times and fewer cycles. This will steadily reduce the pressure until it falls below the pressure switch activation point (Factory Start Pressure Setting) and turns the pump on to bring the pressure back up. The built-in pressure tank holds a certain amount of water and if there is a minor leak in the piping system the water will slowly leave the pressure tank. “What is the purpose of the built-in pressure tank?”Ī. It is designed to help keep the motor from repeatedly cycling on and off due to small flow demand or a minor leak in your water system.

“Can the ‘start pressure setting’ be adjusted?”Ī. The TQ Series pumps are supplied with a factory preset pressure switch and are not designed to be field adjusted. It is imperative to fill the pump with water before operation as dry running causes irreparable damage to the mechanical seal. However, the pump must always be checked for prime if not used for a prolonged period of time. The TQ pumps have a built-in check valve, that will allow the pump to then pump water from depths of 25 feet or less without the worry of priming the pump each time as long as a foot valve is installed at the suction inlet. The TQ Series pumps must be primed before operation. “Are the TQ Series pumps self-priming?”Ī. No. The preset pressure switch activation point for each model is provided in the pump specifications chart listed under “Factory Start Pressure Setting (PSI).” The incoming water pressure must be lower than the preset activation point otherwise the pump will not start. The pump will start when the pressure is BELOW the pressure switch activation point, or the water flow rate is greater than 0.7 GPM. Either one of these will activate the pump depending on water consumption. Frequently Asked QuestionsĪ. The TQ pumps have a built-in pressure switch and internal flow switch.
