It prevents unpleasant odors from rising and ensures proper water drainage. When a leak occurs, it can cause damage and make the system uncomfortable to use. An effective repair and a few precautions can prevent the problem from recurring.   <\/p>\n\n<h2 class=\"wp-block-heading\">Identifying the cause of a siphon leak<\/h2>\n\n<p class=\"wp-block-paragraph\">Before intervening, it&#8217;s essential to understand why the siphon is leaking. The most common causes are : <\/p>\n\n<ul class=\"wp-block-list\">\n<li>A worn or incorrectly positioned seal, no longer guaranteeing a watertight seal.<\/li>\n\n\n\n<li>Insufficient or excessive tightening of fastening nuts, which can lead to leaks.<\/li>\n\n\n\n<li>A build-up of waste or limescale, causing clogging and water overflow.<\/li>\n\n\n\n<li>A crack in the siphon, due to wear or impact.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">A visual inspection can often pinpoint the source of the problem.<\/p>\n\n<h2 class=\"wp-block-heading\">Repairing a leaking drain<\/h2>\n\n<h3 class=\"wp-block-heading\">Seal replacement<\/h3>\n\n<p class=\"wp-block-paragraph\">In most cases, a leaking siphon is caused by a damaged seal. To replace it : <\/p>\n\n<ol class=\"wp-block-list\">\n<li>Remove the siphon by unscrewing the nuts by hand or with pliers.<\/li>\n\n\n\n<li>Check the condition of the gasket and replace it with a new one of the same diameter.<\/li>\n\n\n\n<li>Clean the bearing surfaces before repositioning the gasket.<\/li>\n\n\n\n<li>Screw the siphon back on, but don&#8217;t overtighten to avoid crushing the seal.<\/li>\n<\/ol>\n\n<h3 class=\"wp-block-heading\">Checking and adjusting tightening<\/h3>\n\n<p class=\"wp-block-paragraph\">An incorrectly tightened siphon can cause leaks. After reassembly, tighten the nuts firmly but lightly. Overtightening can crush the seal and cause leakage, while undertightening can allow water to pass through.  <\/p>\n\n<h3 class=\"wp-block-heading\">Cleaning the siphon and pipes<\/h3>\n\n<p class=\"wp-block-paragraph\">A clogged siphon can cause water to back up, leading to leaks. Regular cleaning is recommended: <\/p>\n\n<ul class=\"wp-block-list\">\n<li>Dismantle the siphon and remove any accumulated residues (hair, grease, waste).<\/li>\n\n\n\n<li>Rinse with hot water to dissolve soap and lime deposits.<\/li>\n\n\n\n<li>Check and clean screw threads before reassembly.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\">Siphon replacement in case of cracks<\/h3>\n\n<p class=\"wp-block-paragraph\">If the siphon is cracked or damaged, simple plugging will not suffice. It must be completely replaced: <\/p>\n\n<ol class=\"wp-block-list\">\n<li>Choose a siphon of the same diameter and compatible with your installation.<\/li>\n\n\n\n<li>Remove the old siphon by unscrewing the fittings.<\/li>\n\n\n\n<li>Fit the new siphon, inserting new gaskets and tightening the nuts.<\/li>\n\n\n\n<li>Test the installation by running water and checking for leaks.<\/li>\n<\/ol>\n\n<h2 class=\"wp-block-heading\">Prevent recurring leaks<\/h2>\n\n<p class=\"wp-block-paragraph\">To prevent the problem from recurring frequently :<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Check seals regularly and replace them at the first sign of wear.<\/li>\n\n\n\n<li>Do not overtighten fittings to avoid damaging threads and seals.<\/li>\n\n\n\n<li>Clean the siphon every three to six months to prevent clogging and residue build-up.<\/li>\n\n\n\n<li>It&#8217;s best to replace with a quality trap, as lower-end models wear out more quickly.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Call on Leader Services<\/h2>\n\n<p class=\"wp-block-paragraph\">If you have recurring leaks or need a lasting repair, Leader Services can intervene quickly to identify and solve the problem efficiently.
