Rapid on-off cycling — short cycling — is one of the fastest ways to wear out a pump. Every start puts mechanical and electrical stress on the motor.<\/p>\n
Waterlogged pressure tank.<\/strong> The most frequent cause. The air charge in the tank has been lost, so there is no cushion and the pump reacts to every small pressure change. Check and restore the pre-charge.<\/p>\n A leak in the system.<\/strong> A dripping tap or a leaking pipe bleeds pressure continuously, so the pump restarts to compensate.<\/p>\n Faulty check valve.<\/strong> If water flows back after the pump stops, pressure drops immediately and it restarts.<\/p>\n Oversized pump.<\/strong> A pump delivering far more than the system needs reaches cut-out pressure almost instantly, then stops.<\/p>\n Pressure switch set too narrow.<\/strong> A small gap between cut-in and cut-out forces frequent starts.<\/p>\n A smart pump with variable-speed control avoids the problem by modulating speed to match demand instead of switching on and off.<\/p>","protected":false},"template":"","faq_cat":[38],"class_list":["post-2626","faq","type-faq","status-publish","hentry","faq_cat-orders"],"_links":{"self":[{"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/faq\/2626","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/faq"}],"about":[{"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/types\/faq"}],"wp:attachment":[{"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/media?parent=2626"}],"wp:term":[{"taxonomy":"faq_cat","embeddable":true,"href":"https:\/\/niagarapumps.ca\/it\/wp-json\/wp\/v2\/faq_cat?post=2626"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}A longer-term fix<\/h2>\n
