A bad location or incorrect distance from the filter and the pool causes common problems such as loss of suction, air intake, overpriming, noise and increased wear of the motor.<\/p>\n\n<!--more-->\n\n<p class=\"wp-block-paragraph\">As professionals in installation and maintenance of filtration systems, we are going to explain you how the correct installation scheme of pump and filter should be, what is the right distance and at what height the pool pump should be placed to ensure performance, durability and safety.<\/p>\n\n<h2 class=\"wp-block-heading\">Swimming pool pump and filter installation drawing<\/h2>\n\n<p class=\"wp-block-paragraph\">The correct order of the hydraulic system is always the same:<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Pool (skimmer and\/or bottom) \u2192 Pump \u2192 Filter \u2192 Filter \u2192 Pool returns.<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">This pool pump installation diagram should not be altered. The pump is never installed after the filter, since its function is to drive the water into the filter media, not to suck it from it.<\/p>\n\n<p class=\"wp-block-paragraph\">In a correct installation, the pump works in suction from the pool and in return to the filter, maintaining a continuous and stable flow.<\/p>\n\n<h3 class=\"wp-block-heading\">Where to install the pool pump<\/h3>\n\n<p class=\"wp-block-paragraph\">The location of the pump directly influences its suction capacity and ease of priming. It is best to install the pump:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>As close as possible<\/strong> to the pool.<\/li>\n\n\n\n<li>On a <strong>firm, level surface<\/strong>.<\/li>\n\n\n\n<li>In a <strong>ventilated and accessible area<\/strong> for maintenance.<\/li>\n\n\n\n<li><strong>Protected<\/strong> from floods and direct rain.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">The shorter and straighter the suction pipe, the lower the head loss and the better the pump will work.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"919\" height=\"720\" src=\"https:\/\/poolcomet.com\/wp-content\/uploads\/2025\/11\/bomba-piscina-bajo-consumo-hayward-max-flo-vs-sp1811vs-piscina.jpg\" alt=\"Consumption of swimming pool pump in kWh and watts according to HP\" class=\"wp-image-406074\" style=\"width:600px\" title=\"\" srcset=\"https:\/\/poolcomet.com\/wp-content\/uploads\/2025\/11\/bomba-piscina-bajo-consumo-hayward-max-flo-vs-sp1811vs-piscina.jpg 919w, https:\/\/poolcomet.com\/wp-content\/uploads\/2025\/11\/bomba-piscina-bajo-consumo-hayward-max-flo-vs-sp1811vs-piscina-300x235.jpg 300w, https:\/\/poolcomet.com\/wp-content\/uploads\/2025\/11\/bomba-piscina-bajo-consumo-hayward-max-flo-vs-sp1811vs-piscina-768x602.jpg 768w, https:\/\/poolcomet.com\/wp-content\/uploads\/2025\/11\/bomba-piscina-bajo-consumo-hayward-max-flo-vs-sp1811vs-piscina-600x470.jpg 600w, https:\/\/poolcomet.com\/wp-content\/uploads\/2025\/11\/bomba-piscina-bajo-consumo-hayward-max-flo-vs-sp1811vs-piscina-80x63.jpg 80w\" sizes=\"auto, (max-width: 919px) 100vw, 919px\" \/><\/figure>\n<\/div>\n<h3 class=\"wp-block-heading\">How high should the pool pump be?<\/h3>\n\n<p class=\"wp-block-paragraph\">One of the most important aspects of the pool pump installation scheme is the head.<\/p>\n\n<p class=\"wp-block-paragraph\">From a technical point of view, <strong>the pump works best when it is below the water level of the pool<\/strong>. In this situation, water arrives by gravity and priming is simpler and more stable. Depending on the height, the following occurs:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Below<\/strong> water level: <strong>optimal<\/strong> suction, less air risk and higher efficiency.<\/li>\n\n\n\n<li>At the <strong>same level<\/strong>: <strong>correct<\/strong> operation, but requires good sealing.<\/li>\n\n\n\n<li><strong>Above<\/strong> the water level: possible, but <strong>increases the risk<\/strong> of de-priming and air ingress<a href=\"https:\/\/poolcomet.com\/en\/blog\/how-to-remove-air-from-the-pool-pump-how-to-bleed-it-and-when\/\" target=\"_blank\" rel=\"noreferrer noopener\">(here we explain how to remove it<\/a>).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">If the pump is elevated, it is essential that the entire suction is perfectly sealed and that priming is carried out correctly.<\/p>\n\n<h3 class=\"wp-block-heading\">How far the pump should be from the swimming pool<\/h3>\n\n<p class=\"wp-block-paragraph\">There is no single distance, but there are clear technical criteria. The pump must be placed:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Close enough to minimize<\/strong> load <strong>losses<\/strong>.<\/li>\n\n\n\n<li><strong>Avoiding long stretches<\/strong> of suction.<\/li>\n\n\n\n<li>With <strong>well dimensioned pipes<\/strong> (usually 50 or 63 mm).<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">As a practical reference, the greater the distance, the more effort the pump must make to aspirate, which translates into higher electrical consumption and wear.<\/p>\n\n<h3 class=\"wp-block-heading\">Correct installation of pump and filter<\/h3>\n\n<p class=\"wp-block-paragraph\">In the <a href=\"https:\/\/poolcomet.com\/en\/blog\/how-to-connect-the-pool-pump-filter-and-electrical-connection-correctly\/\" target=\"_blank\" rel=\"noreferrer noopener\">connection between pump and filter<\/a> it is essential to maintain correct alignment.
