Swimming pool pumps help to circulate water in the pool to remove impurities and mix chemicals used for cleaning. The pump works by pulling water from the main drain and skimmers and pushing it through a series of systems for filtration, heating and sanitisation. The water is then pumped back into the pool where the process starts all over again. Therefore, the pump is integral to the proper functioning of a swimming pool.  This article highlights some basic facts about pool pumps that first-time pool owners might want to know.

Leaky Pumps -- Several factors can contribute to leaking pumps including worn out threads and damaged shaft seal among others. The threaded fitting that moves water from the pump might shrink due to excessive heat thereby allowing water to leak. A plumber can replace the fitting with a high-temperature variant while using an appropriate sealant. Notably, damaged shaft seals can cause water to drip down a pump's seal plate. Therefore, replace the worn out parts with ozone/salt service seals made using materials that are resistant to salt and chlorine. Note that disassembling and putting back the pump together is a complicated affair that is best done by an experienced pool specialist. 

Pool Pump Motors -- Pump motors are designed to withstand harsh outdoor environment while delivering continuous service for years. On average, and with proper maintenance, a motor can last for 8-10 years before requiring replacement. However, the service life can be extended if you house the device accordingly while ensuring proper air flow. Also, during winter you can uninstall the pump to prevent rusting. There is no need to lubricate pool pump motor bearings because they are sealed.     

Energy Efficient Pool Pumps -- Pool owners spend a considerable sum of money per year to keep their pools sparkling clean. Furthermore, the cumulative emission levels from such an energy-consuming process are staggering. Therefore, it is vital that pools continue to operate, but with energy saving technology in mind. It is recommended to use a small, high-efficiency pump that costs less to purchase and maintain. However, you would have to modify other components of the pool for efficient pool circulation through reduced hydraulic resistance. Also, consider using a filter with a high flow rate while increasing the size of pipes or decreasing pipe length.

Overheating Pool Pump -- Pool pumps can run too hot because increased rotations exert pressure on the pump's mechanical components. Friction and electrical malfunction can lead to the overheating problem. If the pump is too hot when you touch it, then that is a telltale sign that it is overheating. Ensure that you install the pump in an area where it can draw adequate fresh air. If you must enclose your pool pump, then use a sunshade as opposed to an enclosed room. Before you upgrade your pump, try improving the flow dynamics and fixing all the leaks to prevent the overheating problem.
