The issue is often related to a buildup of food waste or debris.<\/p>\r\n<h2>What \"not draining\" usually means.<\/h2>\r\n<p>If water is sitting in the sink or draining very slowly when using the waste disposal, it usually indicates a restriction somewhere in the system.<\/p>\r\n<p>This restriction prevents water from flowing away as it should.<\/p>\r\n<h2>The most common causes<\/h2>\r\n<h3>Buildup inside the disposal unit<\/h3>\r\n<p>Food waste, grease, or debris can collect inside the unit over time.<\/p>\r\n<p>This can reduce how effectively it breaks down waste and allow material to build up.<\/p>\r\n<h3>Blocked trap under the sink<\/h3>\r\n<p>The trap is the curved section of pipe beneath the sink.<\/p>\r\n<p>It can collect debris and become partially or fully blocked, restricting flow.<\/p>\r\n<h3>Blockage further down the drain<\/h3>\r\n<p>If the pipe beyond the disposal is blocked, water will not be able to drain away properly.<\/p>\r\n<p>This can cause water to back up into the sink.<\/p>\r\n<h3>Grease and food residue<\/h3>\r\n<p>Grease can solidify inside pipes and combine with food particles.<\/p>\r\n<p>This creates a buildup that slows or blocks drainage.<\/p>\r\n<h2>Why the disposal may still run<\/h2>\r\n<p>In many cases, the disposal unit will still operate even if the drain is blocked.<\/p>\r\n<p>This can make it seem like the unit is working when the problem is actually in the pipework.<\/p>\r\n<h2>What you can try<\/h2>\r\n<p>There are a few basic steps you can take:<\/p>\r\n<ul>\r\n<li>Run water while operating the disposal to help flush debris<\/li>\r\n<li>Check for obvious blockages near the sink outlet<\/li>\r\n<li>Avoid putting additional waste into the system until the issue is resolved<\/li>\r\n<\/ul>\r\n<p>If the blockage persists, further investigation may be needed.<\/p>","ptb_mjr_ask_mj":"<p><strong>If it's not draining, something's stopping the water from getting away.<\/strong><\/p>\r\n<p>The issue is usually in the pipework rather than the unit itself.<\/p>","ptb_mjr_service_text_2":"<h2>How MJ Robertson approaches waste disposal issues<\/h2>\r\n<p>MJ Robertson is a maintenance company specialising in plumbing across Christchurch.<\/p>\r\n<p>When a waste disposal is not draining, the focus is on identifying where the blockage is occurring.<\/p>\r\n<p>This may involve:<\/p>\r\n<ul>\r\n<li>Checking the disposal unit and connections<\/li>\r\n<li>Inspecting the trap and pipework<\/li>\r\n<li>Clearing any blockages affecting the flow<\/li>\r\n<\/ul>\r\n<p>The aim is to restore normal drainage and prevent recurrence.<\/p>\r\n<h2>When to arrange help<\/h2>\r\n<p>It is worth arranging assistance if:<\/p>\r\n<ul>\r\n<li>The sink remains blocked or slow to drain<\/li>\r\n<li>You cannot locate the blockage<\/li>\r\n<li>The issue continues after basic checks<\/li>\r\n<\/ul>\r\n<p>Prompt attention can help avoid further buildup.<\/p>\r\n<h2>Final thought<\/h2>\r\n<p>A waste disposal that is not draining in Christchurch is usually caused by a blockage somewhere in the system.<\/p>\r\n<p>Identifying and clearing that blockage is the key to restoring normal flow.<\/p>"},"ptb_taxonomy":{"category":[{"term_id":30,"name":"Waste Disposals","slug":"waste-disposals","term_group":0,"term_taxonomy_id":30,"taxonomy":"category","description":"Waste disposal problems in Christchurch.
